Sports Nutrition

Creatine, protein, and performance supplements — what actually works for training and recovery.

📖 The Story (click to collapse)

Meet Jake, Sarah, and Marcus​

Jake runs 3-4 times a week — nothing crazy, just staying active. He saw an ad for a pre-workout with "explosive energy" and a recovery formula with 15 ingredients. He spent $120 on supplements last month and isn't sure what's actually helping.

Sarah goes to the gym 5 days a week, mixing strength training and cardio. She's trying to build muscle but struggles to eat enough protein with her busy schedule. She bought whey protein but also grabbed BCAAs because the store associate said they're "essential for recovery." Between protein, BCAAs, a fancy pre-workout, and a post-workout formula, she's spending $80-100/month.

Marcus is training for a marathon. He read that elite athletes use supplements, so he bought creatine, protein, electrolytes, beta-alanine, glutamine, and a recovery drink. His supplement drawer is full, but he's not sure what's actually making a difference or if he's taking the right things for endurance training.

The Reality They All Need to Hear​

The sports nutrition industry thrives on confusion and false promises. Pre-workouts claim explosive energy, protein powders promise rapid muscle gain, and countless "performance enhancers" fill store shelves. Most of it is marketing.

But a handful of supplements have decades of research proving they actually work:

  • Creatine — The most studied, most effective ergogenic supplement
  • Protein — Convenient way to meet elevated needs
  • Caffeine — Proven performance enhancer
  • Electrolytes — Essential for hydration and function

What Jake needs: Simple caffeine before runs (coffee works), electrolytes for longer runs. That's it. Save $100/month.

What Sarah needs: Protein powder to hit her daily target (1.6-2.2 g/kg), creatine for strength gains. Skip the BCAAs and complicated formulas. Save $40/month.

What Marcus needs: Electrolytes for long runs, protein for recovery, caffeine for occasional performance boost. Creatine offers minimal benefit for pure endurance. Save $50/month.

These aren't magic. They support hard training — they don't replace it. But when used correctly, they provide measurable benefits without draining your wallet.

🚶 The Journey: Your First Month with Sports Nutrition​

🚶 The Journey: Your First Month with Sports Nutrition

Week 1: Starting Out​

Creatine Loading (Optional) OR Standard Approach:

  • Loading protocol: 20g/day split into 4 doses (5g each) for 5-7 days
  • Standard protocol: 3-5g daily (skip loading; takes 3-4 weeks to saturate)
  • Track: Bodyweight (expect 1-3 lbs water retention), strength performance, recovery

Protein Timing:

  • Calculate your target: 1.6-2.2 g/kg bodyweight
  • Track daily intake for 7 days to establish baseline
  • Add protein powder only if consistently falling short of targets

What to expect:

  • Creatine: If loading, may notice fuller muscles and slight weight gain within days
  • Protein: Better satiety, easier to hit targets
  • Energy: No immediate changes (creatine isn't a stimulant)

Week 2-4: Adjusting & Building​

Creatine adjustments:

  • If loaded: Switch to 3-5g daily maintenance
  • If standard dosing: Continue 5g daily; muscles still saturating
  • Monitor: Strength in key lifts, workout performance, rep capacity
  • Weight gain 1-3 lbs is normal (intramuscular water, not fat)

Protein optimization:

  • Fine-tune timing: 20-40g post-workout, spread rest throughout day
  • Experiment with flavors and types (whey vs. plant-based)
  • Track: Are you hitting 1.6-2.2 g/kg daily consistently?

Performance milestones to watch:

  • Week 2-3: May notice 1-2 extra reps on key lifts
  • Week 3-4: Power output improving (sprints, jumps, explosive movements)
  • Recovery: Feeling fresher between training sessions

Red flags:

  • Significant GI upset from creatine → Switch to Creapure (highest purity) or reduce dose
  • Protein causing bloating → Try whey isolate (lactose-free) or plant-based
  • No water weight gain on creatine → May be a non-responder (rare) or need more time

Month 2+: Optimization & Performance Gains​

Creatine saturation complete:

  • Muscles fully saturated by week 3-4
  • Strength gains should be measurable: 5-15% improvement in key lifts
  • Maintain 3-5g daily indefinitely (no need to cycle)

Protein habits solidified:

  • Hitting targets should feel automatic now
  • Body composition changes visible (if training and diet support it)
  • Post-workout recovery improved

Caffeine strategy (if using):

  • Pre-workout: 200-400mg 30-60 min before training
  • Monitor tolerance: If effects diminishing, cycle off for 5-7 days
  • Track: Performance, energy, sleep quality (avoid afternoon dosing if sleep-sensitive)

Electrolyte timing (for endurance/long sessions):

  • Sessions >60 min: Start using during training
  • Heavy sweaters: Increase sodium replacement (500-1500mg/hour)
  • Track: Cramping, energy levels, recovery

Long-term optimization:

  • Monthly check: Are supplements still providing value?
  • Creatine: Continue indefinitely (excellent safety profile)
  • Protein: Adjust based on training volume and goals
  • Pre-workout: Use strategically, not daily, to prevent tolerance

Cost check:

  • Budget approach: Creatine ($5-7/month) + coffee ($5) = $12/month
  • With protein: +$25-30/month = $40/month total
  • Are results worth it? Creatine almost always yes; protein depends on whether you'd hit targets without it

🧠 The Science: How Performance Supplements Work​

🧠 The Science

Mechanisms of Action​

Creatine Monohydrate:

  • ATP regeneration: Creatine phosphate donates phosphate group to ADP, rapidly regenerating ATP (immediate energy system)
  • How it helps strength: More ATP available = more reps, more weight, more total volume
  • Cellular hydration: Draws water into muscle cells, creating anabolic signaling environment
  • mTOR activation: Cell swelling triggers protein synthesis pathways
  • Timeline: Saturates muscles in 3-4 weeks (or 5-7 days with loading)
  • Effect: 5-15% strength/power improvement, 1-2 kg lean mass gain

Protein Supplementation:

  • Muscle protein synthesis: Provides amino acids (especially leucine) to trigger mTOR pathway
  • Leucine threshold: ~2.5-3g leucine per meal to maximally stimulate MPS
  • Digestion speed matters:
    • Whey: Fast (peaks in 60-90 min) — ideal post-workout
    • Casein: Slow (6-8 hours) — ideal before bed for sustained amino acid delivery
  • Protein quality: PDCAAS and DIAAS scores measure bioavailability
  • Optimal total intake: 1.6-2.2 g/kg for muscle building (beyond this shows diminishing returns)

Caffeine:

  • Adenosine receptor antagonism: Blocks adenosine (fatigue signal), increasing alertness and reducing perceived effort
  • Catecholamine release: Stimulates epinephrine/norepinephrine release → mobilizes fat, increases heart rate, improves focus
  • Calcium release: Enhances calcium release in muscles → stronger contractions
  • CNS stimulation: Improves motor unit recruitment and power output
  • Metabolic boost: 3-11% increase in metabolic rate (modest: ~50-100 cal/day)
  • Effective dose: 3-6 mg/kg bodyweight (200-400mg for most people)

Beta-Alanine:

  • Carnosine buffering: Beta-alanine combines with histidine to form carnosine in muscle
  • Hydrogen ion buffering: Carnosine buffers hydrogen ions (acid) produced during high-intensity exercise
  • Performance benefit: Delays fatigue in efforts lasting 1-4 minutes (e.g., 400m sprints, intense CrossFit WODs)
  • Saturation: Takes 2-4 weeks of daily dosing to saturate muscles
  • Side effect: Harmless tingling sensation (paresthesia) at doses >800mg

Electrolytes (Sodium, Potassium, Magnesium):

  • Sodium: Primary electrolyte lost in sweat; critical for nerve signaling and muscle contraction
  • Fluid balance: Sodium holds water in bloodstream, maintaining blood volume during exercise
  • Performance impact: Sodium depletion → cramping, fatigue, reduced cardiac output
  • Sweat losses: 500-2000mg sodium per hour depending on sweat rate
  • Potassium/Magnesium: Support muscle contraction and nerve function; losses smaller than sodium

Evidence Tiers​

BCAAsWeakN/ARecovery (only if protein intake low)Unnecessary if eating adequate protein
GlutamineWeakN/ARecovery, immune (endurance athletes)Minimal benefit for most

Why Creatine Is So Effective​

The phosphocreatine system:

ATP (energy) → ADP (spent energy) + Phosphate
Creatine-P (stored) → Creatine + Phosphate
Phosphate + ADP → ATP (energy regenerated)

Why this matters for training:

  • Heavy lifting uses ATP system (lasts 8-10 seconds without regeneration)
  • Creatine supplementation increases phosphocreatine stores by ~20%
  • More phosphocreatine = faster ATP regeneration = more reps at heavy weight
  • Over time: more volume = more muscle growth

Genetic variability:

  • ~20-30% of people are "non-responders" (already have high muscle creatine saturation)
  • Vegetarians/vegans respond better (lower baseline creatine from diet)
  • Responders typically see 20-40% increase in muscle creatine; non-responders <10%

Warning Signs (Need to Adjust)​

Red FlagAction Required
GI upset, bloating (creatine)Switch to Creapure (highest purity), take with food, or split dose to 2.5g twice daily
Protein powder causing gas/bloatingTry whey isolate (lactose-free) or plant-based protein; may be lactose intolerance
Anxiety, jitters from caffeineReduce dose by 50%; avoid stacking with other stimulants; check total daily caffeine
Heart palpitations (pre-workout)Stop immediately; likely too much caffeine or other stimulants; see doctor if persists
Weight gain >5 lbs in week 1 (creatine)Some excess water retention; ensure adequate hydration; weight will stabilize
No strength gains after 4 weeks (creatine)May be non-responder (rare); ensure taking 5g daily; check training program
Dehydration despite water intakeCreatine increases water needs; drink more water (especially in hot conditions)
Caffeine tolerance (no energy boost)Cycle off caffeine for 5-7 days to reset tolerance
Muscle cramps despite electrolytesIncrease sodium intake (some people need >1500mg/hour); ensure adequate fluid

Troubleshooting by Pattern​

Pattern: "Creatine causing bloating or stomach issues"

  • Signal: Low-quality creatine or taking too much at once
  • Action: Switch to Creapure (German-manufactured, highest purity), take with food, split dose (2.5g AM + 2.5g PM), ensure adequate water intake

Pattern: "No weight gain on creatine after 2 weeks"

  • Signal: Possible non-responder, not taking enough, or need more time
  • Action: Verify you're taking 5g daily consistently; vegetarians/vegans usually respond strongly; give 4 weeks total; if still no response, may be in the 20-30% non-responder category

Pattern: "Gaining weight too fast on creatine (concerned about fat gain)"

  • Signal: Water retention (normal), not fat gain
  • Action: Understand this is intramuscular water (beneficial for performance); typically 1-3 lbs in first 2 weeks, then stabilizes; not fat; muscles may look fuller (positive)

Pattern: "Protein powder not helping with muscle gains"

  • Signal: Likely not the protein—check total daily intake and training
  • Action: Track total protein (food + powder); ensure hitting 1.6-2.2 g/kg; check training program (progressive overload?); adequate calories for muscle building?

Pattern: "Pre-workout works great first time, then nothing"

  • Signal: Caffeine tolerance developing rapidly
  • Action: Don't use pre-workout daily; reserve for key workouts only; cycle off caffeine 1 week per month; reduce dose to 100-200mg

Pattern: "Cramping during long runs despite taking electrolytes"

  • Signal: Sodium needs may be higher than product provides OR you're a "salty sweater"
  • Action: Increase sodium (try 1000-1500mg/hour); check for white salt residue on skin/clothes after runs (sign of high sodium loss); consider salt tablets for ultra-endurance

Example 3: David, Powerlifter​

His situation:

  • 32 years old, competing in powerlifting
  • Training 4x/week (heavy, low-rep focus)
  • Goal: Maximize strength in squat, bench, deadlift
  • 200 lbs bodyweight (91 kg)

His protein target:

Budget-Friendly Approach: Essentials Only​

For someone on a tight budget:

The stack:

  • Creatine monohydrate (bulk powder): ~$15-20 for 3-4 months supply = $5-7/month
  • Coffee for caffeine: $5-10/month
  • Total: $12-17/month

What you get:

  • The most effective supplement (creatine)
  • Performance-enhancing caffeine
  • Everything else can come from food

When to add protein powder:

  • Only if consistently falling short of 1.6-2.2 g/kg from food
  • Budget option: Unflavored whey concentrate in bulk (~$25/month)

Total cost with protein: $40/month maximum

What Doesn't Work: The Expensive "Stack"​

Meet Jake, who spent $150/month on supplements:

His stack (before correction):

  • Pre-workout formula: $45/month
  • BCAAs: $30/month
  • Glutamine: $25/month
  • Testosterone booster: $40/month
  • Creatine (in pre-workout): Underdosed
  • Protein: $35/month

Results: Marginal to none beyond what creatine and protein alone would provide

The correction:

  • Creatine monohydrate: $7/month
  • Caffeine pills: $5/month
  • Protein powder: $25/month
  • New total: $37/month

Savings: $113/month

Results: Nearly identical to the $150/month stack. Realized the expensive pre-workout was mostly caffeine, BCAAs were redundant with protein, glutamine had no benefit, testosterone booster didn't work.

Lesson: The supplement industry profits from complexity. Stick to evidence-based basics.

💪 Creatine: The Gold Standard​

Why Creatine Works​

Creatine is the most researched and most effective sports supplement available. It's not a steroid, not a stimulant — it's a naturally occurring compound found in meat and fish that your body also produces.

What creatine does:

Evidence-Based Benefits​

BenefitEvidence LevelMagnitude
Increased strengthVery strong (100+ studies)5-15% improvement
Increased power outputVery strong5-15% improvement
Muscle mass gainsStrong1-2 kg additional lean mass
Sprint performanceStrongImproved repeated sprints
Brain health/cognitionEmergingBenefits for vegetarians, sleep-deprived
Bone healthEmergingMay support bone density

Who Benefits Most​

  • Strength/power athletes — Weightlifters, sprinters, CrossFit
  • Athletes in intermittent sports — Soccer, basketball, hockey
  • Vegetarians/vegans — Lower baseline creatine stores
  • Older adults — Combats age-related muscle loss
  • Those seeking cognitive support — Especially vegetarians

Forms of Creatine​

The standard — and still the best

AspectDetails
Research500+ studies; most-studied form by far
EffectivenessGold standard; all other forms compared to it
CostCheapest per serving
PurityLook for "Creapure" for highest purity

Bottom line: Unless you have a specific reason to use another form, creatine monohydrate is the best choice.

How to Take Creatine​

Daily maintenance (no loading):

FactorRecommendation
Dose3-5 grams daily
TimingAnytime (consistency matters more)
With foodMay improve absorption slightly
DurationSafe for long-term daily use

Saturation timeline: 3-4 weeks to fully saturate muscles

Who Should Be Cautious​

  • Those with pre-existing kidney disease (consult doctor first)
  • Those taking nephrotoxic medications

For everyone else: Creatine has an exceptional safety profile after decades of research.

🥤 Protein Supplements​

Why Protein Powder Exists​

Protein powder isn't magic — it's just a convenient source of protein. Whole foods are generally superior, but protein powder helps when:

  • You struggle to meet elevated protein needs through food
  • You need quick post-workout nutrition
  • You're traveling or have limited food access
  • You prefer liquid calories around training

How Much Protein Do You Need?​

GoalDaily Protein
General health0.8 g/kg body weight (RDA minimum)
Active individuals1.2-1.6 g/kg
Muscle building1.6-2.2 g/kg
Fat loss (preserve muscle)1.8-2.4 g/kg
Endurance athletes1.2-1.6 g/kg

Example: 80 kg (176 lb) person building muscle: 128-176g protein daily

Types of Protein Powder​

The gold standard for most people

TypeDescriptionBest For
Whey Concentrate70-80% protein; contains lactoseBudget-friendly, tastes best
Whey Isolate90%+ protein; minimal lactoseLactose-sensitive, lower calories
Whey HydrolysatePre-digested; fastest absorptionPost-workout (marginal benefit)

Advantages:

  • Complete amino acid profile
  • High in leucine (muscle-building trigger)
  • Fast absorption (ideal around training)
  • Most research support
  • Generally best taste

Disadvantages:

  • Not suitable for dairy-free/vegan
  • Some experience bloating (try isolate)

Quality Considerations​

FactorWhat to Look For
Third-party testingNSF Certified for Sport, Informed Sport
Protein per serving20-25g+ with minimal fillers
Amino acid profileListed on label (watch for amino spiking)
Added ingredientsAvoid excessive sugars, artificial ingredients
Heavy metalsThird-party tested products minimize risk
Amino Spiking

Some companies add cheap amino acids (glycine, taurine) to boost "protein" content without providing muscle-building benefits. Look for products that list the full amino acid profile or are third-party tested.

How to Use Protein Powder​

TimingPurposeAmount
Post-workoutRecovery, muscle protein synthesis20-40g (25-40g for larger individuals)
Between mealsMeet daily protein target20-30g
Before bedOvernight recovery (casein or blend)30-40g

The 40g threshold: For maximizing muscle protein synthesis, 40g may be superior to 20g for larger individuals or after full-body training. More than 40g shows diminishing returns per meal.

⚡ Pre-Workout Supplements​

What Actually Works​

Most pre-workout formulas are overpriced combinations of caffeine with underdosed "proprietary blends." Here's what the evidence actually supports:

The proven performance enhancer

AspectDetails
Effective dose3-6 mg/kg body weight (200-400 mg for most)
Timing30-60 minutes before training
BenefitsReduced perceived effort, increased power, improved endurance
Effect size2-4% performance improvement

Cautions:

  • Don't exceed 400-600 mg/day total
  • Tolerance develops; consider cycling
  • Avoid afternoon/evening if sleep-sensitive
  • Some are genetic slow metabolizers (feel jittery, can't sleep)

DIY Pre-Workout Stack​

More effective than most commercial products:

IngredientDosePurpose
Caffeine200-400 mgPerformance, focus
Citrulline malate6-8 gBlood flow, pump
Beta-alanine (optional)3-5 gEndurance (take daily; timing doesn't matter)

Cost: Significantly cheaper than pre-made formulas at proper doses.

🏃 Post-Workout & Recovery​

What Actually Matters​

The "anabolic window" has been exaggerated. You don't need to slam protein within 30 minutes or lose your gains. But post-workout nutrition does matter:

Post-Workout Recommendations​

FactorRecommendation
Protein20-40g within 2-3 hours (not urgent)
Carbs0.5-1 g/kg if training again within 24 hours
Hydration16-24 oz per pound lost during training
TimingTotal daily intake matters more than timing

Recovery Supplements​

SupplementEvidenceWhen It Helps
ProteinStrongMeeting daily protein needs
CreatineStrongStrength, power, recovery
Tart cherry juiceModerateReducing DOMS, inflammation
Omega-3sModerateInflammation, possibly recovery
MagnesiumModerateSleep quality, muscle function
BCAAsWeakUnnecessary if eating adequate protein
BCAAs Are Usually Unnecessary

BCAAs (branched-chain amino acids) are the most overhyped recovery supplement. If you're eating adequate protein from food or whey, you're already getting plenty of BCAAs. They only make sense for fasted training or very low protein intakes.

💧 Electrolytes & Hydration​

Why Electrolytes Matter​

Electrolytes are minerals that conduct electrical impulses in your body. They're critical for:

  • Muscle contraction
  • Nerve function
  • Fluid balance
  • Heart rhythm
  • Blood pressure

The main exercise-relevant electrolytes: sodium, potassium, magnesium, calcium

When You Need Electrolyte Supplementation​

SituationNeed Level
<60 min moderate exerciseWater usually sufficient
>60 min exerciseSodium replacement beneficial
Heavy sweatingSodium + possibly potassium
Hot/humid conditionsHigher electrolyte needs
Endurance events (2+ hours)Full electrolyte replacement
Low-carb/keto dietHigher sodium needs
Cramping issuesMay indicate electrolyte deficit

Sweat Rate and Sodium Loss​

Sweater TypeSodium LossSweat Sodium Concentration
Light sweater500-1000 mg/hour300-600 mg/L
Moderate sweater1000-1500 mg/hour600-1000 mg/L
Heavy/salty sweater1500-3000+ mg/hour1000-2000 mg/L

Salty sweater signs: White residue on skin/clothes, excessive cramping, sweat tastes very salty

Electrolyte Products​

TypeBest ForNotes
Tablets (Nuun, etc.)Convenience, moderate trainingUsually lower sodium
Powders (LMNT, etc.)Higher sodium needs, customizationMix to preference
Sports drinks (Gatorade)Carbs + electrolytesOften high sugar; dilute if needed
Salt capsulesUltra-endurance, heavy sweatersPrecise sodium dosing

Hydration Guidelines​

TimingRecommendation
Before exercise16-20 oz 2-3 hours before
During exercise4-8 oz every 15-20 min
After exercise16-24 oz per pound lost

Color check: Pale yellow urine = well hydrated. Dark yellow = drink more.

🔧 Troubleshooting​

Common Problems & Solutions (click to expand)

Problem 1: Creatine Causes Bloating or Stomach Discomfort​

Why it happens:

  • Taking too much at once (especially during loading)
  • Taking on empty stomach
  • Poor quality product with impurities

Solutions:

  • Skip loading; use 3-5g daily instead of 20g loading dose
  • Take with food to slow absorption
  • Switch to Creapure (highest purity creatine monohydrate)
  • Split dose (2.5g twice daily)
  • Ensure adequate hydration

When to be concerned: Persistent GI issues after trying these adjustments (rare; consider medical evaluation)

Problem 2: Pre-Workout Makes Me Jittery, Anxious, or Unable to Sleep​

Why it happens:

  • Too much caffeine for your tolerance
  • Genetic slow caffeine metabolizer
  • Taking too late in the day
  • Other stimulants in formula

Solutions:

  • Reduce caffeine dose by 50% and reassess
  • Try stimulant-free pre-workout (citrulline + beta-alanine)
  • Cut off caffeine 6-8 hours before bed (some need 10+ hours)
  • Switch to simple caffeine to avoid mystery stimulants
  • Consider if you need pre-workout at all (many workouts don't require it)

Alternative: Use caffeine only for key workouts, not every session

Problem 3: Protein Powder Upsets My Stomach​

Why it happens:

  • Lactose intolerance (whey concentrate)
  • Milk protein sensitivity
  • Artificial sweeteners (sucralose, acesulfame K)
  • Poor quality protein with additives

Solutions:

  • If using whey concentrate: Switch to whey isolate (99% lactose-free)
  • If whey isolate still bothers you: Try plant-based (pea + rice blend)
  • If sweeteners are the issue: Find unsweetened or naturally sweetened versions
  • Try taking with food rather than alone
  • Reduce serving size and increase frequency

Last resort: Egg white protein or just focus on whole food protein sources

Problem 4: Not Seeing Results from Supplements​

Why it happens:

  • Unrealistic expectations (supplements enhance training, don't replace it)
  • Not taking consistently (especially creatine)
  • Not taking enough time (creatine takes 3-4 weeks to saturate)
  • Diet and training aren't dialed in
  • Taking ineffective supplements

Solutions:

  • Check basics first: Are you training consistently? Eating adequate protein? Sleeping enough?
  • Creatine: Ensure 3-5g daily for at least 4 weeks before evaluating
  • Protein: Track intake — are you actually hitting 1.6-2.2 g/kg?
  • Be realistic: Creatine adds 5-15% performance, not 50%
  • Assess what you're taking: If it's not creatine, protein, caffeine, or electrolytes, consider dropping it

Reality check: Supplements provide 5-10% optimization. If results aren't happening, look at the other 90%: training, nutrition, sleep, consistency.

Problem 5: Creatine Causing Weight Gain​

Why it happens:

  • Water retention in muscle cells (this is normal and beneficial)
  • Typically 1-3 lbs in first few weeks

Solutions:

  • Understand this is GOOD: Increased muscle cell hydration is part of how creatine works
  • Not fat gain: It's intramuscular water, which supports performance
  • If competing in weight-class sport: May need to stop creatine 1-2 weeks before weigh-in
  • For aesthetic concerns: Slight fullness in muscles is generally positive; give it 4-6 weeks to assess

When to reconsider: If you're in a weight-class sport or need to make weight for an event

Problem 6: Supplements Too Expensive​

Why it happens:

  • Buying fancy brands and formulations
  • Taking unnecessary supplements
  • Shopping at retail stores instead of online

Solutions:

  • Creatine: Buy bulk creatine monohydrate online ($15-20 for 3-4 months)
  • Protein: Compare price per serving; bulk unflavored is cheapest
  • Caffeine: Coffee or caffeine pills (~$5/month vs $40 pre-workout)
  • Electrolytes: DIY formula (costs pennies vs $30+/month)
  • Cut the fluff: BCAAs, glutamine, proprietary blends — eliminate these
  • Shop online: Amazon, Bulk Supplements, MyProtein often 50% cheaper than GNC/Vitamin Shoppe

Budget approach: Creatine ($15) + protein if needed ($25) + coffee = $40/month maximum for most people

❓ Common Questions (click to expand)

Do I need protein powder to build muscle?​

No. You can absolutely build muscle eating only whole foods. Protein powder is a convenient tool for meeting elevated protein needs, nothing more. Food first; powder if it helps you hit your targets.

Is creatine safe long-term?​

Yes. Creatine has been studied for decades with an excellent safety profile. No evidence of harm in healthy individuals with normal kidney function. It's one of the most-researched supplements available.

Should I take BCAAs?​

Probably not. If you're eating adequate protein (especially from animal sources or whey), you're already getting plenty of BCAAs. They only make sense for fasted training or very low protein intakes. Save your money.

Do pre-workouts work?​

The caffeine in them works. Most other ingredients are either underdosed or unsupported by evidence. You're usually better off with simple caffeine and optionally citrulline/beta-alanine at proper doses.

How much protein can I absorb at once?​

The "30g limit" is a myth. Your body can absorb more; it just takes longer. For muscle protein synthesis optimization, 20-40g per meal is typical, with larger individuals or post-full-body training potentially benefiting from 40g. Total daily intake matters more than per-meal optimization.

Do I need to cycle creatine?​

No. There's no evidence that cycling creatine provides any benefit. It's safe for continuous daily use. Some people cycle to reset water weight, but it's not necessary for effectiveness or safety.

Key Assessment Questions:

  1. "What's your primary training goal?" (muscle building, endurance, fat loss, general fitness)

    • Muscle building → Creatine + protein (1.6-2.2 g/kg)
    • Endurance → Electrolytes + protein (1.2-1.6 g/kg); skip creatine
    • Fat loss → Protein (1.8-2.4 g/kg) + optional caffeine
    • General fitness → Protein if needed; minimal supplements required

  2. "Are you currently hitting protein targets?" (calculate: 1.6-2.2 g/kg for muscle, 1.2-1.6 g/kg for endurance)

    • If yes → Protein powder not needed
    • If no and struggling → Protein powder is useful tool

  3. "What supplements are you currently taking and how much are you spending monthly?"

    • Identify waste (BCAAs, glutamine, testosterone boosters, overpriced blends)
    • Opportunity to simplify and save money

Recommendations by Goal:

GoalPriority 1Priority 2SkipRed Flags
Build muscleCreatine 5g dailyProtein if needed for targetsBCAAs, glutamine, test boostersTaking 5+ supplements; spending >$80/month
Increase strengthCreatine 5g dailyCaffeine pre-workoutBCAAs, most pre-workout blendsNot tracking strength progress
Improve enduranceElectrolytes (>60min)Protein for recoveryCreatine, BCAAsNeglecting sodium replacement
Lose fatProtein 1.8-2.4 g/kgCaffeine (optional)Fat burners, most weight loss supplementsRelying on supplements vs. deficit

Common Mistakes:

  1. Spending $150/month on supplements as recreational athlete → "Let's simplify to creatine ($7) + protein if needed ($25) + caffeine ($5) = $37/month maximum."

  2. Taking BCAAs while already using protein powder → "BCAAs are redundant if you're eating adequate protein. You're wasting $20-30/month."

  3. Expecting creatine to help marathon performance → "Creatine is excellent for strength and power, but provides minimal benefit for pure endurance. Focus on electrolytes for long runs."

  4. Not taking creatine due to fear of weight gain → "The 1-3 lbs weight gain is intramuscular water, not fat. This is part of how creatine works and is beneficial for performance."

  5. Buying "natural testosterone boosters" → "Over-the-counter testosterone boosters (Tribulus, fenugreek) have weak evidence and minimal effect. Focus on creatine and adequate protein—proven to work."

Coaching Scenarios:

  • "I want to build muscle fast. What supplements?" → "Creatine monohydrate (5g daily) and adequate protein (1.6-2.2 g/kg) are your only proven options. Creatine provides 5-15% strength gains, allowing more training volume = more muscle over time. If you're hitting protein targets from food, you don't need powder. Total cost: $7-40/month depending on protein needs."

  • "Training for marathon. Should I take creatine?" → "Creatine has minimal benefit for pure endurance like marathon training. Focus on: 1) Electrolytes for runs >60 min (500-750mg sodium/hour), 2) Protein for recovery (1.2-1.6 g/kg daily), 3) Caffeine for race day if helpful. Save your money—skip the creatine for this goal."

  • "I'm not seeing results. Should I add more supplements?" → "Before adding supplements, let's check fundamentals: Are you training consistently? Eating adequate protein? Sleeping 7-9 hours? In a caloric surplus (for muscle) or deficit (for fat loss)? Supplements optimize a solid foundation—they don't create results on their own. Fix basics first."

Red Flags:

  • Kidney disease or nephrotoxic medications + creatine → Medical consultation required
  • Stacking multiple high-caffeine products (>600mg/day) → Cardiovascular risk; reduce immediately
  • Under 18 asking about testosterone boosters → Do not recommend; refer to basics
  • Spending >$100/month as recreational athlete → Opportunity to simplify and save

Common Mistakes to Catch​

Red Flag: User taking too many supplements

  • Example: "I'm taking protein, BCAAs, creatine, glutamine, pre-workout, post-workout formula, multivitamin, and testosterone booster"
  • Response: "That's a lot of overlap and unnecessary expense. Let's simplify: creatine and protein are your core. BCAAs are redundant if you're taking protein. Glutamine isn't well-supported. Most testosterone boosters don't work. Let's cut this down to save you $50-80/month."

Red Flag: Unrealistic expectations

  • Example: "I just started taking creatine yesterday and haven't noticed anything yet"
  • Response: "Creatine takes 3-4 weeks to fully saturate muscle stores (or 1 week if loading). Give it a month of consistent use before evaluating. Results will be subtle — 5-15% strength improvement, not dramatic overnight changes."

Red Flag: Buying into marketing hype

  • Example: "I saw this new pre-workout with a proprietary blend that promises explosive energy and massive pumps"
  • Response: "Proprietary blends hide actual doses, usually because ingredients are underdosed. You're better off with simple caffeine (200-400mg) and optionally citrulline (6-8g) at known, effective doses. It'll be cheaper and more effective."

Red Flag: Wrong supplement for goal

  • Example: "I'm training for a marathon. Should I take creatine?"
  • Response: "Creatine is excellent for strength and power, but provides minimal benefit for pure endurance like marathon training. Focus on electrolytes for long runs, protein for recovery (1.2-1.6 g/kg), and caffeine for key workouts. Save your money."

Red Flag: Neglecting basics

  • Example: "I'm not seeing results. Should I add more supplements?"
  • Response: "Let's check the fundamentals first: Are you training consistently? Sleeping 7-9 hours? Eating adequate protein? Supplements optimize an already-solid foundation — they don't fix poor training or nutrition. They're the last 5-10%, not the first 90%."

Red Flag: Falling for "natural testosterone boosters"

  • Example: "Will this testosterone booster help me build muscle faster?"
  • Response: "Over-the-counter 'testosterone boosters' (Tribulus, fenugreek, etc.) have weak evidence and minimal effect on testosterone levels. The only legal supplements proven to build muscle are creatine and adequate protein. Focus on those, plus solid training and sleep."

Example Coaching Scenarios​

Scenario 1: New Lifter Wants to Build Muscle​

User: "I just started lifting weights 3 months ago. I want to build muscle. What supplements should I take?"

Mo Response: "Great work starting your lifting journey! Here's what will actually help:

Essential:

  • Creatine monohydrate: 5g daily. This is the most effective, researched supplement for building strength and muscle. Start here.
  • Protein: Aim for 1.6-2.2 g/kg body weight daily. If you're hitting this through food (chicken, fish, eggs, dairy, legumes), you don't need powder. If you struggle to eat enough, protein powder is a convenient tool.

Optional:

  • Caffeine: 200-400mg before workouts can improve performance. Coffee works great.

Skip:

  • BCAAs (redundant if eating protein)
  • Testosterone boosters (don't work)
  • Mass gainers (just eat more food or make your own: oats + protein powder + banana)
  • Complicated pre-workout formulas

Budget: $15-20/month for creatine, $25-30/month if adding protein powder.

At 3 months in, your biggest gains will come from consistent training, eating enough total calories and protein, and sleeping well. Supplements are the cherry on top, not the foundation."

Scenario 2: Endurance Athlete Overspending​

User: "I'm training for a half-marathon. I'm currently taking creatine, protein, BCAAs, glutamine, beta-alanine, and a pre-workout. Am I missing anything?"

Mo Response: "You're actually taking too much for endurance training. Let's streamline:

Keep:

  • Protein: 1.2-1.6 g/kg daily for recovery is good. Keep this.
  • Caffeine from pre-workout: Useful for key workouts. But you probably don't need the whole pre-workout — coffee or caffeine pills are cheaper and equally effective.

Add:

  • Electrolytes: This is what you're missing. For runs >60 minutes, sodium replacement is crucial. DIY electrolyte drink (1/4-1/2 tsp salt + lite salt in water) costs pennies.

Drop:

  • Creatine: Minimal benefit for pure endurance. Save $15/month.
  • BCAAs: Unnecessary if you're eating protein. Save $20-30/month.
  • Glutamine: Weak evidence for endurance. Save $20/month.
  • Beta-alanine: Only helps efforts 1-4 minutes, not sustained running. Save $20/month.

Savings: $70-90/month. Put that toward race entry fees or new running shoes!

Focus on hydration (with electrolytes), adequate carbs for fueling long runs, and protein for recovery."

Scenario 3: User Experiencing Side Effects​

User: "I started taking creatine a week ago and I've gained 4 pounds. Is this normal? I'm worried it's fat."

Mo Response: "Completely normal — and actually a sign creatine is working!

What's happening: Creatine increases water retention inside muscle cells. This is intramuscular water, not fat. You'll typically gain 1-3 lbs in the first 1-2 weeks.

Why this is good:

  • Increased muscle cell hydration is part of how creatine improves performance
  • Muscles may look slightly fuller (this is positive)
  • It's not fat gain, not bloating — it's a functional adaptation

What to do:

  • Continue taking 3-5g daily
  • Stay well-hydrated
  • Give it 4-6 weeks to fully assess strength and performance gains
  • The initial water weight will stabilize

When to reconsider:

  • If you're in a weight-class sport and need to make weight
  • If you experience persistent stomach discomfort (try taking with food, or switch to Creapure for purity)

Otherwise, this is exactly what should happen. Focus on performance improvements — more reps, more weight, better recovery."

Scenario 4: Budget-Conscious User​

User: "I can only afford about $30/month for supplements. I lift 4x/week and do cardio 2x/week. What should I prioritize?"

Mo Response: "$30/month is plenty for the essentials. Here's your best bang-for-buck approach:

Tier 1: Must-haves (~$20/month)

  • Creatine monohydrate: Buy in bulk online (~$15-20 for 3-4 months supply). This is $5-7/month. Non-negotiable for lifting.
  • Caffeine: Coffee or caffeine pills (~$5/month). Use before key lifting sessions.

Tier 2: If room in budget (~$10/month)

  • Protein powder: Only if struggling to hit 1.6-2.2 g/kg from food. Buy bulk unflavored whey online — can find for $25-30/month.

What to skip:

  • Pre-workout formulas ($40-50/month) — caffeine does 90% of the work
  • BCAAs — unnecessary waste
  • Most other supplements

Budget breakdown:

  • Minimal approach: Creatine ($5-7) + coffee ($5) = $12/month. Spend the rest on quality whole foods.
  • With protein: Creatine ($5-7) + coffee ($5) + protein ($20-25) = $30-37/month

Money-saving tips:

  • Buy bulk online (Amazon, Bulk Supplements, MyProtein)
  • Unflavored is cheaper than flavored
  • DIY electrolytes (salt + lite salt) instead of buying tablets
  • Watch for sales (protein powder often 30-50% off)

You don't need a lot of supplements. Focus on training hard, eating well, and sleeping. These essentials will cover you."

Red Flags to Watch For​

Immediate concern — recommend medical consultation:

  • User has kidney disease or takes nephrotoxic medications (creatine caution)
  • User reports severe GI distress, allergic reactions, or other serious side effects
  • User is under 18 asking about testosterone boosters or aggressive supplement stacks
  • User mentions disordered eating patterns combined with supplement use

Caution/Education needed:

  • User buying expensive proprietary blends instead of proven basics
  • User taking same supplement multiple times (e.g., creatine in pre-workout + standalone)
  • User expecting supplements to replace training and nutrition
  • User cycling creatine unnecessarily
  • User taking potentially dangerous stimulants (DMAA, DMHA)
  • User combining multiple high-caffeine products (>600mg/day)

Opportunity to simplify/save money:

  • User taking 5+ supplements
  • User spending >$80-100/month on supplements as recreational athlete
  • User taking BCAAs, glutamine, or other low-evidence supplements
  • User buying retail instead of online bulk

Educational moment:

  • User doesn't know their protein intake (g/kg)
  • User thinks "natural" supplements can boost testosterone significantly
  • User believes in the "30-minute anabolic window"
  • User thinks they need to load creatine or cycle it
  • User believes protein powder is superior to whole food protein
