Benefits
Antioxidant and anti-inflammatory
In one small manufacturer-run randomized, placebo-controlled trial of 24 adults with rheumatoid arthritis, CuroWhite at 250 or 500 mg per day lowered the inflammatory markers CRP and ESR over three months. Beyond that single small trial, the antioxidant and anti-inflammatory activity attributed to tetrahydrocurcumin comes from laboratory work on curcumin and its metabolites, not from human studies of this product.
Stable, near-colorless form
Hydrogenation is intended to make the curcuminoids more stable and near-colorless. No human study of this product has compared its absorption against ordinary curcumin, so better absorption is a formulation goal rather than a measured result.
Skin and cosmetic use
Its near-colorless form makes it easy to blend into topical cosmetic products without turmeric's yellow tint. That is a formulation property of creams applied to the skin, not an oral benefit, and no human study has tested swallowed CuroWhite for any skin outcome.
Mechanism of action
Tetrahydrocurcumin activity
Tetrahydrocurcumin neutralizes free radicals and inhibits inflammatory enzymes, often more stably than curcumin itself.
Enhanced absorption
Structural modification improves solubility and uptake, raising the amount of active curcuminoid reaching tissues.
Clinical trials
Randomized, double-blind, placebo-controlled trial of CuroWhite in rheumatoid arthritis patients. (Jacob et al. 2019, Journal of Traditional and Complementary Medicine)
24 adults with rheumatoid arthritis, randomized to 250 mg, 500 mg, or placebo once daily for 3 months.
Both CuroWhite doses produced significant reductions in DAS28, ESR and CRP versus placebo over three months. The trial was small (n=24) and conducted by the manufacturer, Aurea Biolabs.
