Creatine helps supply rapid energy to muscles and occurs naturally in meat and fish. The body also makes some itself. A normal mixed diet supports baseline needs, although the amounts used in supplement studies are higher than a typical meal provides.
Creatine monohydrate has good evidence for improving performance in repeated high-intensity exercise and may have selected uses in older adults, but it does not replace training, sleep or adequate food. Products with numerous added ingredients are not necessarily better.
Children, pregnant people and anyone with kidney disease or relevant medication should seek professional advice first. Choose a batch-tested product if you compete in sport, and discuss unexplained weakness or fatigue with a clinician rather than self-treating.
This article offers general information and does not replace advice from someone who knows your medical history. If you are pregnant, take regular medicine or live with a long-term condition, speak to your GP, nurse, pharmacist or a registered dietitian before making a major change to the way you eat.
Creatine in everyday food
Creatine occurs naturally in meat and fish, with smaller amounts in a mixed diet and little in plant foods. The body also makes its own creatine.
This does not mean everyone needs more meat. Tinned fish and modest meat portions can fit an omnivorous plan, while plant-based diets can still provide adequate protein without providing much creatine.
When supplements enter the conversation
Creatine monohydrate has good evidence for some strength and power goals, and research is exploring uses in older adults and particular conditions. It is different from proprietary pre-workout blends.
A steady dose is often used instead of a loading phase, but dosing should not come from this article. Ask a pharmacist, dietitian or clinician if you have kidney disease, take regular medicine or are unsure whether it is suitable.
Cooking without turning dinner into chemistry
Dinner does not need to become a chemistry experiment. Plan satisfying protein foods and treat a supplement as a separate decision rather than an ingredient to add to family meals.
Lentils can stretch chilli, fish works well with frozen vegetables, and recipe panels can help compare protein without relying on expensive bars.
Plant-based and pescatarian kitchens
Pescatarians obtain some creatine from fish. Vegans generally have lower dietary intake, but that is separate from whether overall protein needs are met through soya, seitan, pulses and grains.
People training intensively may wish to discuss creatine monohydrate with a sports dietitian. Front-of-pack athletic branding is not a reliable guide to dose, purity or value.
Safety and who should ask first
Pregnancy, breastfeeding, adolescence, kidney disease and significant dehydration require individual advice. Creatine can increase body weight through water held in muscle, which is an expected effect rather than fat gain.
Keep all supplement tubs away from children and stop using a product if it causes concerning symptoms while seeking appropriate advice.
Shop and plan like a kitchen, not a locker room
If you eat animal products, place fish and meat in the week because you enjoy and value the meals, not solely to chase creatine. Vary fish species and follow current advice for pregnancy and mercury where relevant.
Store any supplement dry, use a measured amount and avoid combining multiple unknown pre-workout products.
