Quick answer
Creatine monohydrate is creatine bound to one molecule of water, and it is the form behind almost all the research showing creatine improves high-intensity training. Myprotein Impact Creatine in Unflavoured is 100% creatine monohydrate, so “Impact Creatine vs creatine monohydrate” is the same thing under a brand name, and it costs 14p per 5g in the 1kg bag at £27.99, checked 3 October 2026. WheyWise read the ingredients on myprotein.com: take 3g to 5g a day and buy the cheapest tested monohydrate you can find.
Creatine monohydrate is the standard form of creatine sold as a supplement: creatine paired with one water molecule, which is what “monohydrate” means. The ISSN creatine position stand calls it the most commonly studied form of creatine, and Myprotein Impact Creatine Unflavoured is 100% creatine monohydrate, checked on myprotein.com on 3 October 2026.
What is creatine monohydrate?
Creatine monohydrate is a supplement form of creatine, a compound found mainly in red meat and seafood, where about 95% of the body's store sits in skeletal muscle. According to the ISSN position stand by Kreider et al., 2017, a normal diet supplies 1g to 2g of creatine a day and leaves muscle stores about 60% to 80% full, and supplementing raises muscle creatine and phosphocreatine by 20% to 40%. Creapure is one branded creatine monohydrate, made in Germany; whether it is worth paying for is covered in Creapure vs generic creatine monohydrate.
Is Impact Creatine the same as creatine monohydrate?
Yes. Myprotein Impact Creatine is creatine monohydrate under a brand name: the Unflavoured version lists one ingredient, creatine monohydrate (100%), and the flavoured versions are 74% to 76% creatine monohydrate with flavouring and sweetener. Myprotein says each serving delivers 3g of creatine monohydrate and that the product is Informed Choice certified.

How much creatine monohydrate should you take?
Take 3g to 5g a day. The ISSN position stand says that dose keeps muscle stores topped up once they are full, and that 3g to 5g a day from the start fills them over 3 to 4 weeks. The fastest route is a loading phase of 5g four times a day, about 0.3g per kg of bodyweight, for 5 to 7 days, then 3g to 5g a day. Timing matters far less than taking it every day.
Is creatine monohydrate worth taking?
For anyone lifting weights or doing repeated sprints, yes. The ISSN concludes that creatine monohydrate is the most effective nutritional supplement available for increasing high-intensity exercise capacity and lean body mass during training, and that it is safe in healthy people. Skip it if you do no high-intensity training. For our picks, see the best creatine UK guide, and compare every creatine by cost per 5g on the creatine price comparison.
Frequently asked questions
What is the difference between Impact Creatine and creatine monohydrate?
There is none in the Unflavoured version: Myprotein lists its ingredients as creatine monohydrate (100%). The flavoured versions are 74% to 76% creatine monohydrate, with flavouring, citric acid and sucralose making up the rest, according to myprotein.com, checked 3 October 2026. Myprotein says each serving gives 3g of creatine monohydrate.
Do you need a creatine loading phase?
No. The ISSN position stand (Kreider et al., 2017) says loading with about 0.3g per kg of bodyweight a day for 5 to 7 days fills muscle stores fastest, but 3g to 5g a day without loading raises them over 3 to 4 weeks. Loading is a shortcut, not a requirement.
Is creatine monohydrate safe?
For healthy people, the ISSN position stand (Kreider et al., 2017) concludes that short- and long-term creatine supplementation, up to 30g a day for 5 years, is safe and well tolerated. Normal doses are 3g to 5g a day. If you have a medical condition, check with your GP first.
