evidence for creatine monohydrate
Our honest take
ON's micronised creatine monohydrate with flavouring and sweeteners. Each 4.5 g scoop gives 3 g of creatine, the amount the authorised claim is based on. It is fairly priced for a flavoured creatine, but the unflavoured version is cheaper per dose.
- You want a flavoured creatine from a trusted brand
- You find sweet drinks too sweet: some buyers do
- You want the lowest cost per dose: unflavoured is cheaper
The science
Creatine monohydrate· evidence: Strong
Creatine monohydrate is the most studied sports supplement there is, with hundreds of controlled trials in people over more than 30 years. It is also the form used in almost all of that research, which is why we treat it as the benchmark other creatine forms have to beat.
The effect builds up as your muscle creatine stores fill, which takes roughly three to four weeks at a steady daily dose, or about a week if you choose to load. You do not need to load or to cycle off.
Research into other uses, such as effects on the brain or on mood, is at an early stage and not established, so we make no claims about them.
Creatine increases physical performance in successive bursts of short-term, high intensity exercise. The beneficial effect is obtained with a daily intake of 3 g of creatine.
Daily creatine consumption can enhance the effect of resistance training on muscle strength in adults over the age of 55 years. The beneficial effect is obtained with a daily intake of 3 g of creatine, together with resistance training that increases in workload over time and is repeated at least three times a week for several weeks, at an intensity of at least 65–75% of one repetition maximum.
Typical dose: 3–5 g a day, taken every day
Safety: Well tolerated by healthy adults at 3–5 g a day. Expect a small gain in body weight (water held in muscle) in the first weeks. Larger doses taken at once can upset the stomach. Creatine can raise creatinine on a blood test, so tell your doctor you take it. Speak to your GP first if you have a kidney condition.
