Sona Red Yeast Rice provides a standardized source of Monacolin K, a natural substance that contributes to the maintenance of normal blood cholesterol levels. This beneficial effect is obtained with a daily intake of 10mg of Monacolin K from fermented Red Yeast Rice preparations. Commercial Red Yeast Rice products have variable levels (if any at all) of Monacolin K. Each Sona capsule is standardized to contain 5mg of Monacolin K per capsule. Taking just two capsules daily of Sona Red Yeast Rice provides the level of Monacolin K recommended to help maintain normal cholesterol levels.
