Trans-resveratrol and quercetin are studied for their antioxidant properties and potential to support metabolic health, though clinical evidence in humans remains limited. Red wine polyphenols provide additional polyphenolic compounds that may support cardiovascular function. These ingredients generally demonstrate a high safety profile based on available research.
