Creatine safety: evidence and practical precautions

Research on creatine monohydrate generally supports its safety for healthy adults using appropriate amounts. That does not mean it is suitable for every person or that side effects are impossible.

What effects might people notice?

Weight can increase because of water retention. Some people report digestive discomfort. Individual responses differ, and taking larger amounts does not guarantee better results.

Kidneys and existing conditions

Evidence from healthy participants should not be applied automatically to people with kidney disease or other medical conditions. If you have a relevant condition, take medication or have questions about a blood test, ask a clinician before using creatine. Tell them which supplements you take.

What about dehydration or hair loss?

Do not treat social-media claims as a diagnosis. Questions about hydration, cramps or hair loss need a careful look at the evidence and your own circumstances. This store cannot determine the cause of symptoms. New or persistent symptoms should be discussed with a qualified professional.

A practical checklist

• Buy clearly labelled, sealed products from an identifiable retailer.
• Follow the current label and do not exceed its recommended amount.
• Do not use a supplement to replace meals, sleep or medical care.
• Seek advice first during pregnancy or breastfeeding, for under-18s, or when managing a medical condition.
