Turmeric used in food is different from a concentrated curcumin supplement. Research on one health outcome should not be treated as proof that turmeric prevents disease or reliably improves memory. Evidence and safety depend on the formulation, dose, and the person taking it.
Turmeric and curcumin: what to know
Turmeric is commonly used as a spice. Supplements may contain concentrated extracts or formulations designed to increase absorption. Evidence for one use or formulation does not automatically apply to another, and a study on one symptom should not be generalized into a claim that turmeric prevents illness or improves memory for everyone.
Safety considerations
The U.S. National Center for Complementary and Integrative Health (NCCIH) notes that taking turmeric by mouth may cause gastrointestinal symptoms. Liver problems have also been reported with some formulations designed to increase absorption. People who take medicines, are pregnant, or have a health condition should ask a healthcare professional before using concentrated extracts.
Check whether a product is a culinary spice or a supplement, and review its amount and other ingredients. Do not use a supplement as a substitute for prescribed medicine, and do not assume that “natural” means safe.
Practical steps
- Take the product label and a list of your medicines to a pharmacist or clinician.
- Ask for advice if you develop an unusual symptom after starting a product.
- Use evidence only for the specific health use it supports; do not treat it as a guarantee of disease prevention.
