Turmeric and curcumin supplements in capsules, tablets, softgels, liquids, gummies and powders. Curcumin is the best-known group of compounds in turmeric root, and supplements present it in several ways: whole turmeric root powder, standardised extracts (often labelled 95% curcuminoids), and enhanced forms such as phytosome curcumin (for example Meriva) or products that add black pepper extract (piperine, sometimes branded BioPerine).
Because the forms differ so much, compare the amount of curcumin or curcuminoids per serving rather than the amount of turmeric powder. Brands include NOW Foods, Life Extension, Jarrow Formulas, Doctor's Best, Himalaya, Osavi, Cytoplan and KIKI Health, and some products combine turmeric with ingredients such as boswellia, bromelain or vitamin D. There are no authorised health claims for turmeric or curcumin, so we describe these products by form and strength only. Some labels advise against use in pregnancy or alongside blood-thinning medication; follow each label's warnings and speak to a healthcare professional if unsure.
How to compare turmeric supplements
Curcumin content: check curcuminoids per serving on the label.
Form: root powder, 95% extract, phytosome or with black pepper extract.
Formula: single ingredient or blended with boswellia, ginger or bromelain.
Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
FAQs
What is the difference between turmeric and curcumin?
Turmeric is the root; curcumin (part of a group called curcuminoids) is a compound found in it. Extracts concentrate the curcuminoids, while root powder contains much less.
Why do some turmeric supplements contain black pepper?
Some products add black pepper extract (piperine). Check the label to see whether a product contains it.
What does 95% curcuminoids mean?
It means the extract is standardised so that 95% of its weight is curcuminoids. Compare the milligrams of extract per serving to see how much you get.
Who should avoid turmeric supplements?
Labels often advise against use in pregnancy or alongside blood-thinning medication. Speak to a healthcare professional if you take medication.
