How to use it
- Enter body weight to get your loading and maintenance doses. Loading phase: 0.3g/kg/day for 5–7 days splits into 4–5 doses. Maintenance: 3–5g/day as a single dose. You can skip loading entirely and reach saturation in 3–4 weeks at maintenance dose.
- Creatine monohydrate is the only form with sufficient evidence. Forms marketed as superior (HCL, ethyl ester, buffered, nitrate) show no advantage in peer-reviewed research at equivalent doses — buy the cheapest monohydrate.
- Expect 1–3 lbs of water weight gain in the first 1–2 weeks as muscle cells draw in water alongside creatine. This is intracellular fluid, not fat, and it may slightly improve muscle protein synthesis.
- Documented effects of creatine supplementation: 3–8% improvement in maximal strength, 1–2% improvement in sprint/power output, faster recovery between high-intensity sets. It does not directly cause fat loss or aerobic improvement.
- Take creatine consistently including rest days — daily consistency matters more than timing. Post-workout delivery shows marginal advantage in some studies but the difference is minor compared to simply taking it daily.
Questions people usually ask
Do I need a loading phase?
No. Loading can saturate stores faster, but many people do fine with a steady maintenance dose and a little more patience.
When should I take creatine?
Timing matters less than consistency. The best time is the time you will actually remember to take it every day.
Why does body weight matter here?
Because bigger athletes often respond better to slightly higher doses, especially during a loading phase.
Is more always better?
No. Past a sensible dose, extra creatine does not keep adding benefit and may only increase stomach discomfort.
Is this tool free and private to use?
Yes. AI Fit Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.
Do these tools replace medical guidance?
No. These outputs are general fitness estimates — not medical advice.
