How much creatine should you take? Your exact dose, done right.

The dosing rules that actually matter

1. Daily, including rest days. Creatine works by keeping your muscles saturated. It is not a pre-workout; skipping rest days slowly drains the tank.
2. 3–5 g is the dose. 5 g is the default. The research uses 3–5 g for maintenance; heavier or very muscular people sit at the top of that range. Above ~5 g the extra is excreted.
3. Loading is speed, not strength. 20 g a day for a week and 3–5 g a day for a month land in the same place. Choose loading if you want the effect this week and your stomach tolerates it. Details: Do you need to load? and Loading phase guide.
4. Timing barely matters. Take it with a meal (carbs or protein slightly improve uptake) at a time you'll remember. Before vs after training: here's the evidence. Morning vs night, and creatine before bed: no difference either.
5. Monohydrate, plain. It's the form used in nearly all research, the cheapest, and the most reliable. HCL, "buffered," liquid or gummy forms are fine only if they deliver a real dose; many gummies don't. See Gummies vs powder.

How much creatine for women

Women typically store less creatine in muscle and respond at least as well to supplementation. The dose is the same range, usually at the lower end by body weight: 3 g for most women under ~65 kg, 5 g above that. Loading is optional and can be scaled to 15–18 g a day rather than a flat 20 g. Everything women ask about (water weight, bloating, hair, cycle, menopause) is answered in Creatine for women and How much creatine should a woman take.

How much creatine is too much?

There's no toxicity at sensible doses, but there's a point of no return on benefit: after saturation, anything over ~5 g a day (or ~0.1 g/kg for very large people) is excreted. During loading, 25–30 g a day is the practical ceiling; above that you're buying stomach upset, not results. "Too much" shows up as bloating, cramps and loose stools, always from the size of a single dose, not the daily total. Split doses fix it. See Loading phase side effects.

What about brain health, aging, vegetarians?

• Brain and mood: studies exploring cognitive effects often use higher doses (5–10 g/day, sometimes 20 g short-term) because the brain saturates more slowly than muscle. 5 g daily is a reasonable place to start; the dose-by-scenario table is on creatine for brain health.
• Over 50: creatine plus resistance training helps preserve muscle and strength; doses in studies are typically 3–5 g/day, sometimes 0.1 g/kg. Creatine without training does much less.
• Vegetarians and vegans: you get almost no creatine from food (natural sources of creatine shows how little even meat-eaters get), so your baseline is lower and the response to 3–5 g a day is often larger.

Water: how much do you need?

Less than the internet says. Creatine pulls water into muscle, so add roughly one or two extra glasses a day, spread out. You don't need to double your intake, and peeing every half hour means too much water, not too much creatine.

Common mistakes

• Taking creatine only on training days.
• Taking 20 g in one go and blaming creatine for the bloating.
• Buying "women's" or "advanced" formulas that deliver 1–2 g per serving.
• Stopping because nothing "felt" different in week one. Creatine shows up in your training log over weeks, not as a sensation.
• Expecting fat loss. It helps you train harder; it doesn't burn fat.

What to expect

Week one: possibly 1–2 lb of water inside muscle and slightly fuller muscles (faster if you loaded). Weeks 2–4: hard sets feel a rep easier. Month 2 and on: strength and lean gains that outpace training alone. Photos and timelines: Creatine before and after.

Safety

Creatine monohydrate at 3–5 g/day is one of the most studied supplements and is considered safe for healthy adults. It raises blood creatinine, a kidney marker, so tell your clinician you supplement before lab tests. If you have kidney disease, take medications that affect the kidneys (some blood pressure drugs, NSAIDs, diuretics), are pregnant or breastfeeding, or are under 18, talk to a clinician first. Thyroid medication (levothyroxine) has no known interaction with creatine, but the same rule applies: ask.
