Evidence notes
Black rice anthocyanins have shown promise in cell and animal studies for antioxidant activity. Human clinical data is limited. Cyanidin 3-glucoside is well-characterized but human efficacy data remain preliminary.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
