In June 2021, an American food supplement company (NOW) conducted multiple standard tests on the efficacy, heavy metals, label accuracy and potential synthetic curcumin addition amount of 23 curcumin products on the market through market research, and the results were less than satisfactory.

The efficacy test was performed by HPLC assay based on curcumin content per particle. This test was performed by NOW in-house laboratory and Eurofins Laboratory. 12 of the 23 products failed the potency test, containing synthetic curcumin, heavy metals, or using gelatin instead of the claimed vegetable source. The company said 11 of the 23 products passed all tests, though the labels contained slightly misleading information.Synthetic curcumin. For example, is made from petrochemicals and is relatively cheap. Some of the products, which are labeled as vegetarian, actually contain gelatin capsules of animal origin.
