What it is
Alternative names and label synonyms: creatine monohydrate, creatine HCl
Creatine is made in the body from amino acids and stored largely in muscle as phosphocreatine. Small amounts also come from animal foods.
Where it comes from
Creatine is a nutrition or performance ingredient that may be food-derived, isolated, fermented, or manufactured depending on the product.
Food sources
Meat and fish contain creatine; plant foods contain little.
Why people use it
Creatine monohydrate can improve repeated high-intensity exercise performance and may support gains in strength or lean mass when combined with resistance training.
Potential benefits and outcome-specific evidence
Ratings apply only to the stated outcome. They are not a grade for the ingredient or proof that a finished product works.
The specific uses described in this profile
Creatine monohydrate can improve repeated high-intensity exercise performance and may support gains in strength or lean mass when combined with resistance training.
What current research says
Evidence for sports performance is stronger than for many supplement ingredients. Findings for cognition, aging, or disease-related outcomes are promising in selected settings but not equally established.
Common forms and differences
Common forms
Creatine monohydrate is the most studied form. Other forms are marketed, but superiority claims often lack convincing comparative evidence.
How forms may differ
Creatine monohydrate is the most studied form. Other forms are marketed, but superiority claims often lack convincing comparative evidence.
Amounts commonly used in research
Amounts used in research vary by outcome, form, population, and study design. A reliable single research amount was not available and no personalized dose is provided.
Important dosage context
Compare creatine amount, serving size, purity testing, and additives. Short-term water-weight gain is not the same as body-fat gain.
Safety and possible side effects
Common concerns include temporary water-weight gain and occasional gastrointestinal discomfort. Evidence in healthy adults is generally reassuring at studied intakes, but individual context matters.
Pregnancy and breastfeeding
Pregnancy and breastfeeding safety has not been independently verified for this ingredient and product form. Use only with qualified professional guidance.
Children and older adults
Children and older adults may have different needs, tolerances, kidney or liver function, and medication risks. Adult marketing directions should not be applied to children.
Potential interactions
Medication interactions
People using medicines that affect kidney function or fluid balance should discuss use with a clinician.
Supplement interactions
Combining supplements can duplicate ingredients, increase total exposure, or create interactions. Check every label and avoid assuming that separate products are safe together.
Who should be cautious
Kidney disease, pregnancy, breastfeeding, adolescence, or medical fluid restrictions warrant individualized guidance.
Product-quality considerations
Quality checks
Prefer a complete label with identity, exact amount, serving, other ingredients, allergen information, lot number, expiry, manufacturer contact, and storage instructions.
Third-party testing
Third-party certification must be verified with the certifier or product record. A badge or seller statement alone is not proof that every lot was tested for identity, potency, contaminants, or banned substances.
How to read the product label
Look for “Creatine” and its synonyms (creatine monohydrate, creatine HCl), the exact form, amount per serving, serving size, proprietary blends, warnings, and certification details.
