Tetrahydrocurcumin(THC) was first discovered in 1978 and is the key bioactive metabolite of curcumin. Our tetrahydrocurcumin powder is validated by advanced scientific techniques such as high performance liquid chromatography (HPLC) and high performance thin layer chromatography (HPTLC).
The molecular structure of THC is very similar to curcumin except that it has four additional hydrogen atoms.
In appearance, curcumin exhibits a bright orange color, while THC is colorless.
We have our own factory and can provide customized services based on customer requirements, including OEM and OEM.
We can create tablets, capsules, and powder.
Curcumin is a very popular ingredient in the supplement industry. THC is its natural metabolite. It is considered to have better absorption and studies have found it to be more stable than curcumin in 0.1 phosphate buffer at pH 7.2 and 37°C. This stability makes it more easily absorbed in the intestine than curcumin.
Studies have shown that THC has superior biological activity compared to other metabolites of curcumin.

Compared to curcumin, tetrahydrocurcumin is a stronger antioxidant, a better blood sugar regulator, and is more effective in regulating blood lipid levels.
THC is more water soluble and has better protection against nitrogen, hydrogen, and low-density lipoprotein. Therefore, it is more effective in inhibiting H2O-induced lipid peroxidation triggered by N2O.
In skin and hair care product formulations. The anti-inflammatory properties of THC make it used in skin whitening and anti-aging products.
As a food additive. THC has the ability to prevent the oxidation of fats and oils, which can extend the shelf life.
