Creatine monohydrate


Creatine is a substance in the body that helps produce energy. It can be taken as a pill or powder. Creatine has been used to improve athletic performance and muscle strength.


10 to 20 grams once daily

What Research Shows

Likely Effective

  • Athletic performance —likely to improve muscle mass, strength, and function B1-B4
  • Muscular dystrophy —likely to improve muscle strength G1

May Be Effective

  • Mental Function —may improve short-term memory and intelligence/reasoning E1

May Not Be Effective

  • Amyotrophic Lateral Sclerosis (ALS) —may not improve symptoms A1
  • Mitochondrial disorders —may not have benefit as an intervention F1

Unlikely to Be Effective

  • Chronic Obstructive Pulmonary Disease (COPD) —unlikely to improve exercise capacity, muscle strength, or quality of life D1
  • Parkinson disease —unlikely to prevent development H1-H3

Not Enough Data to Assess

  • Cardiovascular disease C1

Safety Notes

It is likely safe to take creatine in small doses for a short time. Not enough studies have been done to say whether it is safe to use for a long period. It is also not known whether it is safe to take by women who are pregnant or breastfeeding.


Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse such as:

  • People with kidney or heart problems should talk to their doctors before taking creatine. It may interrupt proper function.
