Creatine Dosage Calculator

How This Calculator Works

Our creatine dosage calculator uses evidence-based formulas derived from the International Society of Sports Nutrition (ISSN) Position Stand on creatine supplementation (Kreider et al., 2017). The calculator considers your body weight to determine personalized loading and maintenance doses.

The Science Behind Creatine Dosing

Loading Phase (Optional)

The loading protocol (approximately 0.3g/kg/day for 5-7 days) was established by Harris et al. (1992) and Hultman et al. (1996). This rapidly increases muscle creatine stores by approximately 20% within one week. The daily loading dose is typically split into 4 equal doses taken throughout the day to improve absorption and reduce potential GI discomfort.

Maintenance Phase

After loading (or from day one if you skip loading), a maintenance dose of 3-5g/day (approximately 0.03-0.05g/kg/day) is sufficient to maintain elevated muscle creatine levels indefinitely. There is no need to cycle creatine — continuous daily use is safe and effective.

Water Intake

Creatine increases intracellular water retention. The calculator recommends a baseline water intake of approximately 35ml/kg body weight plus an additional 500ml to account for creatine supplementation, with more on training days. Adequate hydration supports optimal creatine function.

Cost Estimates for Malaysia

Monthly cost estimates are based on the Malaysian market price range of RM0.017-0.083 per gram of creatine monohydrate, reflecting the range from budget options like PharmaNutri (~RM40/300g) to premium products like Optimum Nutrition (~RM150/300g). Actual costs vary by brand and retailer.

Frequently Asked Questions

How accurate is this creatine dosage calculator?

This calculator uses ISSN (International Society of Sports Nutrition) guidelines from Kreider et al. (2017). The standard 3-5g/day maintenance dose is appropriate for most adults. Body weight-based dosing (0.03-0.1g/kg) provides more personalized recommendations. Individual responses may vary.

Should I use the loading phase option?

Loading (20g/day for 5-7 days) saturates muscle creatine stores in about 1 week, while skipping loading takes 3-4 weeks to reach the same level. Both approaches work equally well long-term. Loading may cause mild GI discomfort in some people.

Does the dosage change based on my goal?

The effective dose (3-5g/day) is the same regardless of whether your goal is muscle building, brain health, or longevity. Your body uses the ATP-phosphocreatine system across all these functions. Consistency matters more than exact dose within this range.
