Product Description
Tetrahydrocurcumin (4-HC) is a premier bioactive metabolite of curcumin, widely recognized as the key active component that delivers curcumin's core benefits. It not only offers equivalent or even stronger biological activity than curcumin, but also effectively solves curcumin's inherent drawbacks of low bioavailability and poor solubility.
What's more, 4-HC is colorless and non-staining, greatly expanding its application range in cosmetics, food supplements and pharmaceuticals.
