Tetrahydro curcuminoids have been medically recognized as being the most bio-active (hydrogenated) metabolites of curcumin from Curcuma longa (Turmeric extract). Unlike other curcuminoids which are usually yellow in color, tetrahydro curcumin has a beige-white appearance - also popularly known as the “white curcumin”. 

Standardized Curcumin is hardly absorbed in the intestines (1). Tetrahydro curcumin is significantly superior to curcumin both in terms of bio-absorption and anti-inflammatory effect, requiring much lower doses but with a much more concentrated and diversified effect (2).

Curcumin C3 Reduct® provided in our product is a patented extract with a verified purity of 98% and manufactured by Sabinsa Corporation, USA. Sabinsa holds multiple patents with clinical data that shows significant efficacy and bio-availability.


BioPerine® is a standardized extract of Piper nigrum, also manufactured by Sabinsa Corporation USA.  In the right proportion, it has been shown to further and significantly increase the bioavailability of Tetrahydro curcuminoids.


  • A highly bio-available patented formula
  • Standardized Curcumin is hardly absorbed in the intestines (1)
  • Significantly superior bio-absorption and anti-inflammatory effect
  • Requires lower doses but with a more concentrated and diversified effect (2)
  • Potentiated by the association with BioPerine®


  • Anti-cancer activity superior to curcumin (3), (4)
  • Protective effects against diabetes and vascular dysfunction by relieving oxidative stress (5), (6)
  • Anti-inflammatory activity superior to curcumin (7)
  • Anti-inflammatory activity at the brain level with positive effects against Alzheimer's and Parkinson's as well as against the oxidative stress induced by Glutamate in the cells of the hippocampus (8), (9), (10)
  • Protective effect in neuropathy by improving the conductivity of motor nerves (11)
