How it works
Calculate your optimal creatine dosage based on your body weight. Get recommendations for both the loading phase (0.3g/kg for 5-7 days) and maintenance phase (3-5g/day). Learn whether loading is necessary and how to time your creatine intake.
How to Use This Calculator
- Enter your body weight in kg or lbs.
- Choose between loading phase or daily maintenance dosing.
- Review your recommended daily grams.
- Split loading doses into 4-5 smaller servings for better tolerance.
Example
Inputs: 75 kg lifter, loading phase
Result: Loading: 22.5 g/day for 5-7 days, then 3-5 g/day maintenance
What it means: Load with 22.5 g/day (split into 4 servings) for a week, then drop to 5 g/day indefinitely.
Tips
- Skipping the loading phase still works — you'll just saturate in 3-4 weeks instead of 1.
- Creatine monohydrate is the most studied and cheapest effective form.
- Take it any time of day — timing doesn't meaningfully affect results.
- Expect 1-2 kg of water weight gain in the first two weeks; this is normal and intramuscular.

Frequently Asked Questions
- Do I need to do a loading phase?
- No, loading is optional. Taking 3-5g/day without loading will fully saturate your muscles in about 3-4 weeks instead of 1 week. Loading (0.3g/kg for 5-7 days) just gets you there faster. Both approaches reach the same end result.
- Is creatine safe?
- Creatine monohydrate is one of the most studied supplements in history. Hundreds of studies confirm it's safe for long-term use in healthy adults. It does not damage kidneys in healthy individuals. Stay hydrated, as creatine increases water retention in muscles.
