Introduction
Creatine's best-proven benefit is more strength and lean muscle from resistance training, at 3 to 5 g a day. Here's what the research supports, how to take it, what happens to your weight and who should check with a doctor first.
Creatine monohydrate, at a usual dose of 3 to 5 grams daily, is proven to increase strength, power, and lean muscle gain when combined with resistance training.
The primary benefit of creatine is to top up a fast energy reserve in muscles, supporting short, hard efforts like lifting, jumping, and sprinting.
While creatine can lead to a slight weight gain of 2 to 4 lbs in the first week, this is due to water retention within muscle cells, not fat gain.
The evidence for benefits like sharper thinking or fat loss is considered weak or unsupported, with significant cognitive improvements primarily observed in adults aged 66 to 76.
Creatine works the same way in women as in men, with the same recommended dose of 3 to 5 grams daily, though research specifically on women is less extensive.
