Frequently Asked Questions

Q1What is creatine loading and do I need to do it?

Creatine loading involves consuming 20 g per day (split into 4 × 5 g doses) for 5–7 days to rapidly saturate muscle creatine stores. Loading is optional—a daily maintenance dose of 3–5 g achieves the same saturation level in approximately 3–4 weeks without the GI discomfort some people experience at loading doses.

Q2How much creatine should I take daily for maintenance?

The standard maintenance dose is 3–5 g of creatine monohydrate per day. Larger individuals (over 90 kg / 200 lbs) may benefit from the higher end of this range. The Creatine Loading Calculator uses your body weight to generate a personalized loading and maintenance recommendation.

Q3What is the best form of creatine to take?

Creatine monohydrate is the most extensively researched, effective, and affordable form. It consistently outperforms or matches all other forms (ethyl ester, buffered creatine, HCl) in peer-reviewed studies. Micronized creatine monohydrate dissolves more easily but offers no additional efficacy benefit.

Q4Do I need to cycle on and off creatine?

No. Current evidence does not support the need to cycle creatine. Long-term studies of up to 5 years show no adverse effects on kidney or liver function in healthy individuals. Continuous use is safe and maintains consistently elevated muscle creatine stores for sustained performance benefits.

What This Calculator Does

The Creatine Loading Calculator gives daily creatine amounts for a loading phase (typically 5–7 days) and a maintenance phase, scaled to body weight.

Formula Used

Loading Dose (g/day) = 0.3 g/kg × Body Weight (kg)
Maintenance Dose (g/day) = 0.03 g/kg × Body Weight (kg)

Example Calculation

An 80 kg person: loading = 24 g/day (split into 4 × 6 g doses), maintenance = 2.4 g/day.

Limitations

These are reference ranges derived from published research. Individual tolerance and response to creatine varies. Split loading into 4–6 doses per day to minimise GI discomfort.
