Red Yeast Rice is a substance extracted from rice that has been fermented with a type of yeast called Monascus purpureus. It is a very popular food in Asian countries where it has been traditionally used for centuries to benefit health. Active compounds called Monacolins, most importantly Monacolin K (also known as lovastatin), are naturally-occurring HMG-CoA inhibitors found in Red Yeast Rice.

It also contains natural Sterols (Beta-sitosterol and Campesterol), Isoflavones, and Monounsaturated Fatty Acids ("healthy fats"). HealthAid® Red Yeast Rice is fortified with Chromium which contributes to the maintenance of normal blood glucose levels.
