Sorghum bicolor Extract (Leaf) with Polyphenols
Also known as: ReDaxin™, Red Sorghum Bioflavonoid Complex, Sorghum leaf extract, Red sorghum extract
ReDaxin™ is a standardized sorghum leaf extract rich in polyphenols and bioflavonoids traditionally used in Asian cuisines for potential antioxidant and metabolic support. Limited clinical research exists on this specific extract in humans, though sorghum is recognized as a polyphenol-rich grain with antioxidant properties.

Evidence notes
While sorghum is recognized as a polyphenol-rich food source with in vitro antioxidant capacity, clinical human trials specifically evaluating ReDaxin™ or sorghum leaf extract at standardized doses are limited. Evidence relies primarily on in vitro studies, traditional use, and general polyphenol biology rather than robust RCT data.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
