Creatine is a naturally occurring compound that supplies energy to muscles. According to the International Society of Sports Nutrition (ISSN), creatine monohydrate is one of the “most effective ergogenic nutritional supplements currently available to athletes with the intent of increasing high-intensity exercise capacity and lean body mass during training”. But it’s not just for elite athletes – people who regularly work out can benefit too and not just those who do power sports, such as weightlifting.

“There are many benefits of creatine,” including “increases in muscle mass and muscle strength, improved brain function, maintenance of muscle mass in an injured limb after injury, adenosine triphosphate increases to improve repeated sprint effort performance, improved recovery periods and endurance capacity, and body composition benefits (increase in lean body mass),” says Aimee O’Keeffe, senior performance nutritionist for England Senior Women’s Rugby. “Creatine supplementation combined with resistance training in elderly populations has also demonstrated some favourable effects on muscle mass, strength, physical performance and bone mineral density.”

Your body produces some creatine but the rest is gained through diet – it’s found in red meat and fish. However, the amount of food you’d need to consume to improve performance is too great, which is where supplementation steps in.

The most extensively studied and effective form is creatine monohydrate. Most brands sell it as pure, unflavoured powder, which can be mixed into drinks such as water or shakes, and it’s generally well tolerated. “When loading with creatine (which is 15-20g of creatine split between two to three doses in a day for five to seven days), there can be an initial gain in weight on the scale due to water retention, but this is temporary and doesn’t last for the duration of supplementing and doesn’t occur in everybody,” explains O’Keeffe.

The recommended daily dosage is between 3g and 5g. “There are no significant differences between pre- or post-training session supplementation,” O’Keeffe explains. “The first step to supplementing is being consistent with creatine once per day”. The ISSN adds that ingesting creatine with carbohydrate or carbohydrate and protein has been reported to more consistently promote greater creatine retention. O’Keeffe adds: “The research suggests there is no need to cycle on and off creatine and it can be consumed daily for long durations.” It is important to note, however, that if you have a health condition or are taking medication, you should check with your doctor before taking any supplement.

Six creatine monohydrate supplements to try

If you’re looking to try creatine monohydrate supplements, we’ve rounded up a selection below. All of the ones we have selected are unflavoured, have no added ingredients and mix well into liquid (apart from the capsules). From experience, warm water or using a mixer such as a Nutribullet works best for mixing them. Similarly, creatine is naturally vegan-friendly but capsules sometimes contain gelatin.

Optimum Nutrition micronised creatine: £26.61,


The particles in this unflavoured creatine monohydrate have been made smaller so the powder mixes more easily into liquid. We found that it does mix well into water although still doesn’t dissolve completely, but this doesn’t matter with any of these supplements as you drink it quickly and can swill the glass around at the end to get the last particles of the product. Each serving provides 3.4g creatine.
