More than Milk Thistle! Liver support with a difference. Developed for reducing liver oxidative stress. Silybin is the most active component of silymarin, derived from the milk thistle. The silybin in Marin is in a phosphatidylcholine complex to increase bioavailability, reaching levels up to 10 times more than 80% standardized milk thistle formulas. Marin also contains both Vitamin E and Zinc at recommended amounts to help support the liver.
