Free creatine calculator: find your optimal dose.

Most adults do well with 3–5 g of creatine monohydrate per day for maintenance. During a loading phase, 15–20 g split into 3–4 doses for 5–7 days is common. Our calculator personalizes these numbers to your body weight and goal.

Loading is optional. It saturates muscle creatine stores faster (about 5–7 days vs 3–4 weeks). Skipping loading and starting with a daily maintenance dose leads to the same final saturation; it just takes longer.

In healthy adults, creatine supplementation at recommended doses is well tolerated and does not harm kidney function. People with pre-existing kidney or liver disease should consult a clinician before use.

Creatine monohydrate has the strongest evidence base, is the most cost-effective, and is equally effective as newer forms for most people. Creatine HCl may be easier on the stomach for some users but typically requires a smaller dose.

Yes. Women can benefit from creatine for strength, bone health, and cognitive support. Dosing recommendations are based on body weight, not gender, so the calculator works for everyone.

Yes, and they often see the biggest improvements because dietary creatine intake from meat and fish is low or absent. A slightly higher maintenance dose may be beneficial.

Timing is flexible. The total daily dose matters most. Many people take it around workouts or with a meal to reduce stomach discomfort, but consistent daily use is more important than the clock.

No. Long-term studies show no need to cycle creatine. Continuous daily supplementation at 3–5 g is safe and effective for maintaining muscle creatine stores.

Use our free creatine calculator to find your personalized dose. Enter your body weight, activity level, goal, and creatine type to get a research-backed loading and maintenance plan.

Aim for about 30–35 ml of water per kg of body weight daily, plus an extra 300–500 ml for every 5 g of creatine. Our calculator includes a water target based on your dose and weight.

A creatine dosage calculator converts your body weight, training goal, and creatine form into a personalized loading and maintenance dose. It follows ISSN guidelines of roughly 0.3 g/kg for loading and 3–5 g/day for maintenance.

Yes. Our calculator works for everyone, including men. Dosing is based on body weight and muscle mass, not gender, so a 70 kg man and a 70 kg woman with similar muscle mass receive the same recommendation.

Creatinine clearance is usually estimated with the Cockcroft-Gault formula or eGFR from a blood test. If you take creatine, tell your clinician, because supplements can slightly raise serum creatinine without harming kidneys.

It is a tool that calculates your creatine dose based on body weight. The standard loading formula is 0.3 g per kg per day, and maintenance is roughly 0.03 g per kg per day.

Yes. A creatine loading calculator gives you a 5–7 day loading protocol based on your weight, then recommends a maintenance dose to keep muscle stores saturated.

It helps you find an appropriate dose for creatine hydrochloride, usually 1.5–3 g per day. HCl is more soluble than monohydrate but does not have stronger evidence for better results.

Creatine can raise serum creatinine, which may make eGFR appear slightly lower. This is usually not kidney damage. Always discuss lab results with a clinician if you supplement with creatine.
