Evidence, with the
right boundaries.
Important distinctionThe sources below examine individual ingredients, different preparations or non-equivalent doses. They are not clinical trials of the complete White Curcuminoid Glutathione formula.
GlutathioneRandomised human study
Oral glutathione and body glutathione stores
A six-month placebo-controlled study evaluated 250 mg or 1,000 mg of glutathione daily. It concerns standalone glutathione at different doses, not this finished formula.
GlutathioneRandomised human study
Oral glutathione and skin melanin index
A four-week trial evaluated 500 mg daily and reported changes in melanin indices at several sites. The dose and preparation differ materially from this product.
GlutathioneRandomised human study
Reduced and oxidised glutathione and skin properties
A 12-week placebo-controlled study evaluated 250 mg daily of reduced or oxidised glutathione. It used standalone glutathione at a different dose, not this yeast-extract formula.
TetrahydrocurcuminScientific review
Identity and preclinical research landscape
The review describes tetrahydrocurcumin as a pale hydrogenated curcumin metabolite and maps predominantly preclinical research. It does not establish a skin outcome for this product.
TetrahydrocurcuminoidsEFSA safety assessment
A safety assessment with a defined boundary
EFSA assessed a standardised >95% tetrahydrocurcuminoid novel food and concluded it was safe at 140 mg/day for adults excluding pregnancy and lactation. That material is not automatically equivalent to this finished formula.
Curcumin & piperineHuman pharmacokinetic study
Piperine and curcumin bioavailability
A small human study examined 2 g curcumin with 20 mg piperine. It supports the ingredient-pairing rationale but uses conventional curcumin and doses far above this reduced-turmeric formula.
