How Much Creatine Should You Take? The Complete Dosage Guide (By Weight & Goal)

The standard creatine dose is 3–5 g/day of creatine monohydrate, taken every day, indefinitely. That's the number the International Society of Sports Nutrition's (ISSN) position stand lands on after reviewing the dosing research, and it barely moves whether you're 130 lb or 230 lb, male or female, or brand new to training.¹ Everything below is the detail underneath that one number: how to adjust it by body weight, whether you should load, whether men and women differ, and what changes if you're taking a form other than monohydrate.

The Short Answer

3–5 g of creatine monohydrate, once a day, every day — no cycling, no days off, no need to time it around a workout. The 2021 ISSN-affiliated review that addressed dosing head-on put it plainly: "accumulating evidence indicates that you do not have to 'load' creatine. Lower, daily dosages of creatine supplementation (i.e. 3-5 g/day) are effective for increasing intramuscular creatine stores, muscle accretion and muscle performance/recovery."² The ISSN's broader position stand backs the same range as the standard maintenance dose.¹

Quick reference:

That table covers almost everyone. The rest of this guide is the reasoning and the edge cases underneath it.

Dosing by Body Weight

Body weight matters less than most online calculators imply. You're not scaling a dose to total muscle mass — you're mainly replacing the roughly 1–2 g of creatine your body breaks down and excretes every day, a rate that stays fairly flat across adult body sizes.¹ That's why a flat 3–5 g/day works for nearly everyone, rather than a sliding per-kilogram formula.

The commonly cited weight-anchored reference dose is about 0.03 g/kg/day — the same figure our women's dosing guide uses. Here's what that looks like against the practical range:

Notice the gap between the two columns, especially at higher body weights — the per-kilogram math consistently lands below the practical dose. That's expected: 0.03 g/kg approximates the daily breakdown rate, not the larger total creatine pool a bigger frame has to fill and defend. Use the practical dose column. If you're at either extreme — well under 120 lb or well over 220 lb — nudge to the low or high end of 3–5 g. Everyone in between just needs 3–5 g and can stop doing math.

Monohydrate vs. Other Forms — Does the Dose Change?

The 3–5 g/day number above is specifically for creatine monohydrate — it's the form nearly all of the dosing research, including the ISSN position stand, was actually run on.¹ If your tub says "monohydrate" or "micronized monohydrate," the dose doesn't change: 3–5 g/day, same serving as everywhere else on this page.

Other forms market a different — usually smaller — number. Creatine HCl is marketed on a much smaller "micro-dose" claim; we cover why that doesn't hold up in our CON-CRET Creatine HCl review. For the full form-by-form breakdown — buffered creatine, citrate, nitrate, ethyl ester, gummies — see types of creatine compared rather than us re-deriving that table here.

Loading vs. No-Loading

Loading gets you to full muscle saturation in about a week; skipping it gets you to the same saturation in about four weeks.² The 2021 ISSN-affiliated review that compared the two directly concluded that ~3–5 g/day for a minimum of four weeks produces creatine stores similar to a traditional loading protocol.² Neither route gets you more saturated than the other — loading just gets you there faster, at the cost of four doses a day and more GI upset along the way.

If you have a competition or deadline inside 30 days, loading is worth it. Otherwise, just start at 3–5 g/day and be patient. For the exact loading protocol, the research behind it, and who genuinely should still load: creatine loading phase.

Can You Split Your Dose?

You don't need to. At a 3–5 g/day maintenance dose, a single serving is small enough to take all at once — split dosing solves a problem you don't have at this dose size.

Splitting earns its keep in two situations: during a loading phase, where the daily total (~20 g) is large enough that dividing it into 3–4 servings genuinely reduces GI upset, and if a single scoop bothers your stomach even at maintenance — some people do get mild discomfort from monohydrate regardless of dose size. If that's you, see does creatine cause bloating? for the full mechanism and fixes. Otherwise, one scoop, once a day, is the simpler and equally effective option.

Dosing for Men and Women

Same dose, same 3–5 g/day. The variable that actually moves the number is body weight and baseline creatine stores — not sex.¹

For men: 3–5 g/day, same as the table above. Guidance sometimes nudges toward the higher end of that range for men, but that's because men average more total body and muscle mass — a body-size effect, not a sex-based one. A 130 lb man and a 130 lb woman need the same dose.

For women: the dose doesn't change either — but the reasons to take it shift across a woman's life, from performance and lean mass in your training years to muscle, bone, and mood support through the menopause transition. That's a big enough topic to deserve its own page: creatine dosing across a woman's life.

Who Should Adjust Their Dose

Most people just take 3–5 g/day and never think about it again. A few groups have a real reason to lean toward one end of that range:

• Vegetarians and vegans. Diet supplies a meaningful share of most omnivores' daily creatine; plant-based eaters get essentially none of it from food. The ISSN position stand notes they start with lower intramuscular creatine stores and may see greater gains from supplementing.¹ Start at the higher end — 5 g/day.
• Older adults. The standard 3–5 g/day dose still applies; there's no evidence establishing a different dose by age alone. What matters more here is consistency — missing doses is the more common failure mode, not an undersized dose.
• Body-weight extremes. If you're well under 120 lb or well over 220 lb, use the low or high end of the body-weight table above (2–3 g or 5 g) rather than the flat 3–5 g midpoint everyone else can default to.

Nobody else needs to adjust anything. If you're not in one of these three groups, 3–5 g/day is the whole answer.

A Quick Word on Timing

Whether you take your 3–5 g in the morning, post-workout, or before bed barely moves the needle — what predicts results is taking it every day, not when. Timing matters far less than consistency; for the actual before/after/anytime research, see creatine timing: before or after your workout?

Bottom Line

3–5 g of creatine monohydrate, once a day, every day, indefinitely. Adjust toward 5 g if you're on the larger end of body weight, vegetarian or vegan, or you'd rather load fast before a deadline; otherwise, don't overthink it. Sex doesn't change the number, timing doesn't change the number, and the form on the label only changes it if you've picked something other than monohydrate.

Frequently Asked Questions

How much creatine should I take per day?

3–5 g of creatine monohydrate, every day, indefinitely.¹ That's the maintenance dose from the ISSN position stand, and it applies to nearly every adult regardless of body weight, sex, or training experience.

Does creatine dosage depend on body weight?

Only at the extremes. A flat 3–5 g/day covers nearly every adult body size, since you're mainly replacing a roughly fixed 1–2 g/day breakdown rate rather than scaling to total muscle mass.¹ Under about 120 lb, 2–3 g/day is usually enough; over about 220 lb, use the top of the range, 5 g/day. Everyone in between doesn't need to run the math.

Can I split my creatine dose?

You can, but you don't need to at 3–5 g/day. Splitting earns its keep during a loading phase, where the daily total (~20 g) is large enough that dividing it into 3–4 servings reduces GI upset, or if a single scoop bothers your stomach even at maintenance. See does creatine cause bloating? if that's you.

Does creatine HCl need a different dose?

Creatine HCl is marketed on a much smaller "micro-dose" claim, often 1–1.5 g/day, based on higher solubility. The 3–5 g/day standard applies to creatine monohydrate specifically, the form nearly all of the dosing research was run on — HCl's lower-dose claim hasn't held up in head-to-head comparisons at equal creatine content. More in our CON-CRET Creatine HCl review.

Do men and women need different creatine doses?

No. Men and women use the same 3–5 g/day maintenance dose.¹ Body weight and baseline creatine stores move the number; sex doesn't. See creatine dosing across a woman's life for how the reasons to take it shift for women specifically.
