Yerba Prima Milk Thistle Extra Strength is more than four times stronger and more bioavailable than Silymarin milk thistle seed extract. It contains clinically proven milk thistle seed extract, plus the assimilation boosting nutrient Bioperine® black pepper extract. Our patented extract has been clinically shown to protect the liver and promote proper liver function.*

Milk Thistle Extra Strength promotes liver health by stabilizing liver cell membranes, by protecting liver cells from damage due to alcohol, chemicals and other toxins through its strong antioxidant effects in the liver, and even by helping to rebuild normal healthy liver tissue.* Milk Thistle Extra Strength contains a patented extract standardized to 33% silybin in a special high-absorption phosphatidylcholine matrix.

Maximum Absorption: Milk Thistle Extra Strength formulas are made with standardized herbal extracts, which are assimilated more completely than common powdered herbs. Bioavailability of our Extra Strength herbs is further boosted by the addition of a patented black pepper extract, Bioperine®.
