Creatine Dosage Calculator: Loading & Maintenance Doses (2026)

How much creatine should you take per day? For most adults, 3–5 g/day of creatine monohydrate is the standard maintenance dose, which reaches full muscle saturation in 3–4 weeks. Want it faster? A loading phase of 20–25 g/day, split into 4–5 doses for 5–7 days, gets you there in about a week. Same endpoint, quicker route. The 1996 Hultman trial (n=31) showed the equivalence directly: 20 g/day for 6 days raised muscle creatine 20%, and 3 g/day for 28 days produced the same 20% rise. So loading is optional, not better. By body weight, the math is 0.3 g/kg/day during loading and 0.03–0.05 g/kg/day for maintenance. One recent finding complicates the picture. A 2025 UNSW trial used a one-week wash-in to separate water retention from real muscle gain, and at 5 g/day it found no measurable muscle beyond what training delivered. Its researchers suggest 10 g/day may be the better target for hypertrophy. For most users, though, 5 g/day still hits the strength and ATP-recycling benefits creatine is known for.

What Is a Creatine Loading Phase?

A creatine loading phase means taking a high dose of creatine monohydrate, typically 20 to 25 grams per day, for 5 to 7 days. You split that into four or five 5-gram servings across the day. Doing so blunts gastrointestinal discomfort and saturates intramuscular creatine stores fast.

Your muscles store creatine naturally, but diet alone fills only 60–80% of their capacity, mostly from red meat and fish at roughly 1–2 grams per day. Supplementing pushes intramuscular creatine to near 100%. That fuller pool matters: phosphocreatine is what regenerates ATP for short, explosive efforts, and a saturated pool does it about 10–40% faster than baseline.

According to Dr. Richard Kreider, Professor at Texas A&M University and lead author of the International Society of Sports Nutrition position stand on creatine, the loading protocol of approximately 0.3 g per kg of body weight per day for 5–7 days is the most well-supported rapid-saturation method.

Creatine loading vs maintenance: what do the numbers show?

The most rigorous direct comparison comes from Hultman et al. (1996, J Appl Physiol), who measured muscle creatine concentration in 31 male subjects across different dosing protocols. Two regimens reached the same destination:

• Loading protocol: 20 g/day for 6 days produced a 20% increase in muscle total creatine concentration. Saturation in under a week.
• Maintenance-only: 3 g/day for 28 days produced the same 20% increase. Same destination, four weeks instead of one.

The ISSN position stand (PMID: 28615996) recommends 3–5 g/day of creatine monohydrate for maintenance, which saturates muscle stores in about 28 days. A loading protocol of 20 g/day (4 × 5 g) for 5–7 days reaches full saturation within a week instead. Both land at the same endpoint, roughly 160 mmol/kg dry muscle weight. Loading just gets there faster; it is not superior over the long run.

How Much Creatine Per Day? Body-Weight Dosing

Most people need 3 to 5 g of creatine daily, the dose set in studies averaging 70 to 80 kg participants. Larger people above 100 kg may benefit from the upper end, around 5 to 8 g. There's no need to scale precisely; a steady daily dose that keeps muscle saturated is what matters.

Body mass affects optimal creatine dosing. The 5 g/day standard was established in studies averaging 70–80 kg participants. Individuals above 100 kg may benefit from 7–10 g/day to reach full muscle saturation, while those under 60 kg can typically achieve saturation at 3 g/day. During loading, the evidence-based range is 0.3 g/kg/day for 5–7 days, which works out to 21 g for a 70 kg individual.

What does that mean in practice? For the vast majority of adults, 3–5 g/day works regardless of exact body weight. Above 5 g the dose-response curve flattens, and anything past saturation leaves in your urine. Body weight earns its keep mainly during loading, where 30 g/day for a 100 kg lifter versus 18 g for a 60 kg runner is a real split.

The Hagstrom 2025 Question: Is 5 g/day Even Enough?

The standard 5 g/day dose has been the default for two decades. In March 2025, a UNSW-led trial published in Nutrients challenged whether that dose actually adds muscle on top of resistance training.

Desai, Pandit, Smith-Ryan, Simar, Candow, Kaakoush, and Hagstrom (2025) randomized 63 adults (34 women, 29 men, average age 31) to either 5 g/day creatine monohydrate or no supplement. Critically, they added a one-week wash-in phase where the creatine group took the supplement but did not exercise. This separated any fluid-driven weight change from real muscle accrual. Then both groups completed 12 weeks of supervised resistance training (three sessions/week).

The result: both groups gained roughly 2 kg of lean body mass over the 12 weeks. The creatine group's additional gain beyond the control group was not statistically significant.

According to senior author Dr. Mandy Hagstrom, who heads the resistance training research program in UNSW's School of Health Sciences: "We've shown that taking five grams of creatine supplement per day does not make any difference to the amount of lean muscle mass people put on while resistance training. The benefits of creatine may have been overestimated in the past, due to methodological problems with previous studies."

Her team's recommendation is 10 g/day, which they think may better support hypertrophy beyond what training alone delivers. No one has tested that dose in a head-to-head wash-in RCT yet. For now it is a hypothesis built on dose-response logic, not direct evidence.

What this means for users: 3–5 g/day still saturates muscle creatine stores, still supports phosphocreatine regeneration, and still has strong evidence for strength and short-burst performance. If your goal is visible muscle gain on top of hard training, the Hagstrom team's argument is that you may need 10 g/day to see it consistently. For more on this topic, see our creatine gummy dosing guide.

When Loading Makes Sense, and When to Skip It

Loading (20 g/day for 5 to 7 days) saturates muscle creatine stores in about one week instead of the three to four weeks that maintenance dosing (3 to 5 g/day) requires. Loading makes sense when you need performance gains within days, such as before a competition or training camp. For most recreational users starting a long-term supplementation plan, skipping the loading phase and going straight to 3 to 5 grams daily is simpler and avoids the GI discomfort and water bloat that higher doses can cause.

Loading is a tool, not a requirement. It exists for situations where the speed of saturation has practical value.

Load when:

• You have a competition or training peak in 2–3 weeks and want the strength benefit before then
• You've been off creatine for months and want to resaturate quickly
• You don't mind GI experimentation and want to skip the slow ramp

Skip loading when:

• You have a sensitive stomach or history of GI issues with supplements
• You want the simplest possible protocol. One scoop daily forever
• You're using creatine for long-term health (cognitive, bone, age-related muscle preservation) rather than a short performance window
• You're new to creatine entirely; start at 3–5 g/day and observe how your body responds before considering higher doses

For most people, especially those starting creatine for general health rather than competitive performance, skipping the load is the cleaner path. Same destination. Less GI risk. One fewer protocol to remember.

What's the maintenance creatine dose after loading?

Once your loading week ends, or from day one if you skipped loading, your maintenance dose is 3–5 g/day. One scoop. Any time. With or without food. Consistency day to day matters far more than the hour you take it.

Muscle creatine stores deplete slowly. Once you stop entirely, intramuscular creatine takes 4–6 weeks to fall back to its pre-supplementation baseline. Miss a day, or even a few, and you lose nothing. The 2025 Antonio et al. Part II review in J Int Soc Sports Nutr puts timing in its place as a tertiary factor; what produces and sustains the effect is consistency over weeks.

For ongoing use over years, the data continues to support safety. The 2017 ISSN Position Stand reviewed long-term studies up to five years at doses as high as 30 g/day and found no adverse effects on kidney function markers, liver markers, or cardiovascular outcomes in healthy adults.

Who Should Be Cautious With High-Dose Creatine Loading

For healthy adults, the safety profile of creatine is one of the strongest in the supplement category. A few groups should still consult a healthcare professional before starting, particularly before attempting a 20+ g/day loading phase:

• People with reduced kidney function. Creatine is metabolized to creatinine, which is filtered by the kidneys. Healthy kidneys handle the increased load without issue. Compromised kidneys may not. If you have any history of impaired renal function, talk to your nephrologist before loading.
• Anyone with elevated creatinine on routine bloodwork. Creatine raises serum creatinine, which can confound the standard eGFR estimate and look worse than reality. Tell your physician you're on creatine before your next lab draw.
• People prone to GI sensitivity. Loading at 20+ g/day pushes the gut's absorption capacity. If you've had issues with osmotic laxatives, magnesium citrate, or sugar alcohols, skip the loading phase entirely.
• People taking diuretics. The combination is understudied and the theoretical interaction (water shifts) suggests caution.
• People in heavy heat training without consistent hydration. Creatine increases intracellular water demand. If you're already cramping or running low on fluids, address that before starting.
• Pregnant or breastfeeding individuals. No clear adverse signals exist, but no large RCTs have been run in these populations either.

None of these are absolute contraindications. They are reasons to skip the loading phase and start at 3–5 g/day, with a conversation with your physician first.

How YourHealthier's Creatine Dose Compares

Our Creatine delivers 5 g of monohydrate per serving, matching the dose used in most strength, lean-mass, and cognitive research. It's the standard maintenance amount, with no loading required. Five grams daily keeps muscle stores saturated for nearly everyone, which is why we use it rather than a token underdose.

Five creatine forms dominate the market, but only monohydrate has the evidence base. Creatine HCl, buffered creatine (Kre-Alkalyn), creatine ethyl ester, and creatine nitrate all claim superior solubility or absorption, yet none has outperformed monohydrate in any published human trial measuring muscle creatine content, strength, or power output. The ISSN explicitly endorses only monohydrate.

All five deliver the same 5 g/day dose used in most RCTs, and the same dose Hagstrom 2025 flagged as suboptimal for muscle hypertrophy specifically. What sets YourHealthier's formulation apart is the electrolyte blend. Creatine pulls water into muscle cells, and that fluid has to come from somewhere. Pairing it with sodium, potassium, and magnesium supports whole-body hydration through the saturation phase.

Why YourHealthier Added Electrolytes to Creatine

Most creatine on the market is pure monohydrate with nothing added. That works, but it ignores what creatine actually does physiologically. By pulling intracellular water into muscle, creatine slightly reduces extracellular fluid volume. For users in hot climates, heavy training cycles, or anyone who under-hydrates, this can amplify cramps and fatigue during the first 1–2 weeks of supplementation.

We added sodium, potassium, and magnesium to address that, not because the creatine itself needs help, but because the body it's loaded into often does. The dose is 5 g monohydrate per scoop, matched to the most-studied range. See our Creatine Hydration Powder, our batch-level Certificates of Analysis, and our Editorial Policy for how every claim here was sourced.

Which creatine protocol should you follow?

Option A, with loading (fastest path): Take 5 g of creatine monohydrate four times a day (20 g total) for 5–7 days, split with meals to ease GI effects. After the first week, drop to 3–5 g daily and stay there.

Option B, without loading (simplest path): Take 3–5 g daily from day one. Give it 3–4 weeks for full muscle saturation. Then just keep going.

Mix creatine with water, juice, or a protein shake. Taking creatine with a carb-containing meal may slightly improve uptake via insulin-mediated transport. For timing details: when to take creatine. For results timeline: how long does creatine take to work. For the weight-gain question: creatine weight gain.

What does creatine stack well with?

Creatine works on the phosphocreatine/ATP system, a distinct cellular energy pathway. It pairs naturally with supplements targeting other systems: NMN 500 mg : for NAD+-driven mitochondrial energy. See NMN benefits and NMN vs NAD . Ashwagandha KSM-66 , for cortisol management during heavy training.

Watch: Layne Norton on Creatine Dosing and Why Loading Is Optional

Dr. Layne Norton (PhD nutritional sciences, University of Illinois) and Dr. Andrew Huberman discuss why creatine monohydrate remains the most cost-effective and well-studied form, why the loading phase is optional rather than required, and how 5 g/day reaches the same intramuscular saturation as a 7-day load over the longer timeline shown in Hultman 1996.

What's new in creatine research (2025–2026)?

Creatine crossed into neurodegenerative territory in 2025 with the first pilot trial in Alzheimer’s patients. Published in Alzheimer’s & Dementia: Translational Research, the single-arm study gave 20 participants 20 g/day for 8 weeks, confirmed feasibility, and reported increased brain phosphocreatine on MRS imaging.

What creatine does at the cellular level and why dosing protocol matters

Creatine monohydrate is the most extensively studied ergogenic supplement in sports nutrition, with over 500 published human trials. Its mechanism is straightforward: creatine phosphate serves as the fastest ATP regeneration pathway during high-intensity, short-duration efforts. When muscle creatine stores are saturated, you can produce more ATP per unit of time, which translates to measurably more force output, more reps before failure, and faster recovery between sets.

The loading versus maintenance debate has a clear answer from the research: both approaches reach the same endpoint. Loading (20 g/day split into 4 doses for 5 to 7 days) saturates muscle stores in about a week. Maintenance-only dosing (3 to 5 g/day from day one) reaches the same saturation by approximately day 28. The practical difference is speed versus convenience. Athletes preparing for a competition in two weeks should load. Everyone else can skip the loading phase and avoid the transient water retention and GI discomfort it sometimes causes.

Creatine's benefits beyond muscle are where dosing gets more interesting. Cognitive studies in sleep-deprived and vegetarian groups used 5 g/day with no loading. The brain leans heavily on phosphocreatine to regenerate ATP during demanding mental work, and topping up stores may blunt the decline that comes with sustained effort or poor sleep. The evidence for women has grown a lot lately. See our creatine for women guide for the latest on bone density, body composition, and hormonal considerations.

The most common dosing mistakes: taking creatine without adequate water (creatine increases intracellular water demand, so dehydration symptoms can emerge), using forms other than monohydrate without evidence justification (creatine HCl vs monohydrate breaks down the comparison), and cycling on and off unnecessarily. The ISSN position stand is clear: continuous daily use at 3 to 5 g/day is safe for all age groups with no documented need for cycling. For the full side effect profile, see is creatine safe.

How should older adults, vegetarians, and teens dose creatine?

The standard 3–5 g/day recommendation was established in studies of trained male subjects averaging 70–85 kg. Three common dosing errors undermine results: taking creatine without food (reduces insulin-mediated uptake by ~25%), skipping rest days (breaks saturation continuity), and using effervescent or liquid creatine (monohydrate degrades to creatinine in solution within hours).

Vegetarians and vegans have lower baseline muscle creatine stores because dietary creatine comes almost exclusively from meat and fish. The Harris 1992 study established that omnivores start with approximately 60 to 80% muscle creatine saturation, while vegetarians start at 40 to 60%. This means vegetarians experience a larger absolute increase from supplementation and may see more pronounced cognitive and physical benefits. The standard 3 to 5 g/day is sufficient, but the time to full saturation without loading may be slightly longer (5 to 6 weeks rather than 4).

Older adults (60+) represent the population with arguably the most to gain from creatine supplementation. Age-related muscle loss (sarcopenia) involves progressive loss of type II fast-twitch fibers, which are the most creatine-dependent. The Candow 2019 systematic review found that creatine combined with resistance training produced significantly greater lean mass gains in older adults compared to resistance training alone. Dosing protocols in these studies ranged from 3 to 5 g/day (maintenance) to 0.1 g/kg/day (body-weight-adjusted). Given that many older adults weigh less than the young adults in standard trials, a body-weight-adjusted dose of 0.05 to 0.07 g/kg/day is a reasonable starting point.

Adolescent athletes often ask about creatine safety. The ISSN 2017 position stand reviewed the available evidence and concluded that creatine monohydrate at 3 to 5 g/day is safe for adolescents engaged in serious training, with the caveat that supervised use and adequate hydration are important. The concern about kidney damage has been specifically addressed and debunked across all age groups in multiple systematic reviews.

What if creatine doesn't seem to work?

Approximately 20–30% of creatine users are classified as non-responders, defined as individuals whose intramuscular creatine levels increase less than 10 mmol/kg after supplementation. Non-response correlates with higher baseline muscle creatine (already near the ~160 mmol/kg ceiling), higher percentage of type I (slow-twitch) muscle fibers, and insufficient carbohydrate co-ingestion to drive insulin-mediated creatine transport.

To start, verify you are using creatine monohydrate specifically. Other forms (HCl, ethyl ester, buffered, liquid) have less evidence and inconsistent bioavailability. If your product does not say "creatine monohydrate" on the label, switch to one that does. Second, check your daily intake: 3 grams per day is the minimum effective maintenance dose, and many people who report non-response are actually taking 1 to 2 grams inconsistently. Third, assess your dietary creatine intake: heavy meat and fish consumers may already have near-saturated muscle creatine stores from food, which means supplementation provides a smaller incremental benefit. Vegetarians and people with low meat intake typically see the largest response.

Beyond that, reconsider your measurement criteria. If you are judging creatine by the scale (weight gain), you may be a responder who is attributing the water retention to failure rather than recognizing it as evidence of muscle saturation. Track strength metrics (1RM or reps at a given weight) over 4 to 6 weeks rather than body weight. Fifth, ensure adequate hydration: creatine increases intracellular water demand, and dehydration limits the muscle volumization effect. A practical target: add 500 mL of daily water intake above your normal baseline when supplementing with creatine.

Do you need to cycle creatine?

Cycling creatine (taking it for 8 weeks, stopping for 4 weeks, repeating) was a common recommendation in the 1990s and early 2000s based on the theoretical concern that continuous supplementation might downregulate the creatine transporter (SLC6A8). This concern has been directly addressed and largely dismissed by subsequent research.

The Candow 2011 study measured creatine transporter gene expression in humans after 5 weeks of creatine supplementation and found no significant downregulation. Muscle creatine stores do gradually return to baseline over 4 to 6 weeks after discontinuation, but they refill when supplementation resumes, confirming that the transporter remains functional. The ISSN 2017 position stand explicitly states that there is no demonstrated need for creatine cycling, and continuous daily supplementation at 3 to 5 g/day is safe indefinitely based on current evidence.

The only scenario where cycling makes practical sense: competitive athletes in weight-class sports who want to shed the 1 to 2 kg of water weight that creatine produces during a pre-competition cut. Discontinuing creatine 3 to 4 weeks before weigh-in allows the intracellular water to normalize while preserving the strength gains accumulated during the supplementation period. Outside of weight-class competition, cycling is unnecessary complexity that interrupts the continuous saturation your muscles need to maintain the performance benefit.

A final point on creatine quality: the European standard for pharmaceutical-grade creatine monohydrate is marketed as Creapure (manufactured by AlzChem in Germany). It is tested to contain fewer contaminants (dicyandiamide, dihydrotriazine) than many generic creatine sources. Whether this purity difference translates to meaningful safety or efficacy advantages is debated, but for people who want the most thoroughly tested raw material, Creapure is the reference standard. Most products that use it will display the Creapure logo on the label. For budget-conscious consumers, any reputable creatine monohydrate with third-party testing is sufficient; the compound itself is simple enough that manufacturing quality differences are small compared to, say, the variation in herbal extracts.

What does creatine do, and why does the dose matter?

Creatine refills phosphocreatine stores in muscle cells, the fastest ATP regeneration pathway during high-intensity efforts lasting 2 to 10 seconds. Every explosive rep, every sprint, every jump pulls from this pool. Saturate it through supplementation and you hold peak power for more reps before fatigue hits. Dosage matters because those stores have a ceiling. Once you reach saturation, around 160 mmol/kg dry muscle weight, the extra is simply excreted. Loading gets you there in a week; maintenance, in a month. Same ceiling either way.

Does creatine make you gain weight?

Yes, but the weight gain is primarily intracellular water, not fat. Creatine is an osmolyte that draws water into muscle cells, increasing total body water by 1 to 3 kg during the first week of a loading protocol. This water is inside your muscle fibers, contributing to muscle volumization rather than subcutaneous bloating. Over subsequent weeks, genuine lean mass accrual adds additional weight if you are training consistently. The Lanhers 2017 meta-analysis measured approximately 1.4 kg of additional lean mass gain over 4 to 12 weeks of creatine supplementation versus placebo in resistance-trained individuals. For more detail, see creatine weight gain.

Is creatine bad for you?

No. Creatine monohydrate is the most thoroughly studied sports supplement in history. The ISSN 2017 position stand concluded it is safe for all age groups at 3 to 5 g/day, with no credible evidence of kidney damage, liver toxicity, or other organ harm. The kidney worry traces back to creatine's metabolite, creatinine, which doctors use as a kidney-function marker. Supplementation raises creatinine, and that bump can look like kidney impairment on a standard blood panel. Telling your physician you take creatine clears up the false alarm. For the complete safety data, see is creatine safe.

What does the ISSN position stand say about creatine loading?

The International Society of Sports Nutrition (ISSN) position stand on creatine is the most authoritative summary of 500+ studies. Their loading recommendation: 5 grams four times daily (20 g/day) for 5 to 7 days, followed by 3 to 5 g/day maintenance. This protocol saturates muscle creatine stores in approximately one week.

The alternative: skip loading entirely and take 3 to 5 g/day from day one. This reaches the same saturation level by week 4. The ISSN acknowledges both approaches as effective; the only difference is the speed to full saturation. No performance or body composition advantage has been demonstrated for loading versus maintenance-only dosing at any timepoint beyond week 4.

Who might benefit from loading: athletes with a competition in 2 to 3 weeks who want maximal creatine stores as quickly as possible. People who want subjective confirmation that creatine is "working" (the rapid water weight gain during loading provides early feedback). Who should skip loading: people prone to GI discomfort (20 g/day can cause bloating and diarrhea), anyone concerned about rapid scale weight increase, and people who plan to take creatine indefinitely (why rush if you have months ahead?). See creatine bloating for the GI management strategies.

How Much Creatine per Day to Build Muscle?

The ISSN position stand recommends 3 to 5 g of creatine monohydrate daily for ongoing muscle-building support (Kreider et al., 2017). A loading phase of 20 g/day split into four doses for 5 to 7 days saturates stores faster but is optional; 3 g/day reaches the same saturation in about 28 days. Body weight above 90 kg may warrant 5 g daily. Timing relative to meals or workouts has minimal impact on long-term results.

How Much Creatine Is Too Much?

There is no established toxic dose in healthy adults, but doses above 10 g in a single sitting commonly cause GI discomfort, bloating, or diarrhea. The well-studied maintenance range is 3 to 5 g/day; exceeding this does not further increase muscle creatine stores because excess is excreted by the kidneys. Chronic megadosing above 20 g/day has not been studied for safety beyond short loading phases.

The Science · Lab Results · Ingredients · Editorial Policy

Does Creatine Make You Sweat More?

Creatine does not directly stimulate sweat glands or raise body temperature. It increases total body water by 1–2 liters, giving your body more fluid for thermoregulation. A 2006 study (PMID: 16416332) found no difference in core temperature or sweat rate during exercise in heat. If you feel sweatier, the likely cause is increased training intensity from creatine's performance benefits.

Does Creatine Make Your Muscles Look Bigger?

Yes, but initially through water, not fiber growth. Creatine pulls water into muscle cells via osmosis, creating a fuller look within 1–2 weeks. A 2003 study (PMID: 12945830) measured a 6.6% rise in thigh muscle volume after 7 days of loading, entirely from water. Over 8–12 weeks of training, creatine supports real protein synthesis, so gains become genuine tissue.

Does Creatine Make Your Butt Bigger?

Creatine alone will not selectively enlarge your glutes. It helps you train harder—more sets, heavier loads—which, combined with targeted glute work (hip thrusts, squats, Romanian deadlifts), accelerates growth there. The initial 2–4 pound water gain distributes across all muscle, not just glutes. Over 8–12 weeks, real hypertrophy grows glutes proportional to training. Creatine is a training amplifier, not a spot-targeting agent.

What Does a High Creatine Level Mean?

High creatinine (above 1.3 mg/dL men, 1.1 women) can indicate impaired filtration, dehydration, high protein intake, recent exercise, or creatine supplementation—significance depends on context. If you supplement creatine, the elevation is an expected artifact since creatinine is its muscle breakdown product. A 2008 study (PMID: 18188581) confirmed elevated creatinine without changed filtration. Tell your doctor to order cystatin C.

What Does High Creatine Kinase Mean?

High creatine kinase (CK) indicates muscle cell damage. Benign causes include intense exercise (CK can spike past 10,000 U/L), trauma, or injections; pathological causes include rhabdomyolysis, heart attack, and muscular dystrophy. Normal resting CK is 22–198 U/L and normalizes within 3–5 days post-exercise. Persistent elevation without exercise warrants investigation. Creatine supplementation does not raise CK—it raises creatinine, a different biomarker.

What Does it Mean if your Creatine is Low?

Low serum creatinine (below 0.6 mg/dL) can indicate reduced muscle mass, malnutrition, severe liver disease, or excessive fluid intake diluting blood. In elderly or bedridden patients, it often reflects muscle wasting (sarcopenia). It can also mask kidney disease by making eGFR appear artificially high. Your doctor interprets it alongside age, muscle mass, and other labs.

Is Creatine Illegal in High School Sports?

No. Creatine is legal in high school sports—no state athletic association bans it. However, some states and districts prohibit school staff and coaches from distributing or recommending supplements to student athletes, which is a liability policy, not a safety ban. Students can legally buy and use creatine on their own. Parents and pediatricians should be involved in the decision.
