The research

We don't make the claims. The studies do.

30+ studies on Setria®.

What the research proves

Because we use Setria® — the exact ingredient and dose from these studies, not a cheap generic — the research proves:

  • Whole-body antioxidant. The antioxidant your other antioxidants rely on to recharge.
  • Liver & detox support. Central to the liver's everyday clean-up work.
  • Skin brightness. Studied for an even, healthy complexion.
  • Immune resilience. Supports the function of immune cells under stress.

These are structure/function statements based on published studies of the ingredient — not on this finished product, and not a promise about any one person. Not evaluated by the FDA.†
