UNDERSTAND THE METHOD

How to use this calculator

Enter adult body weight and select a published protocol to check its arithmetic. Loading uses 0.3 g/kg/day for 5–7 days, commonly divided into four servings. Maintenance uses 0.03 g/kg/day. Loading is optional.

What the result can tell you

This is a published-rate conversion, not an individual supplement prescription. It does not assess kidney function, medication interactions, pregnancy, or suitability for a medical condition. Review those questions with a clinician before use.
