Main highlights

OUTSTANDING VALUE: Our Organic Milk Thistle contains 7500 mg strength per capsule AND 120 capsules per bottle - an amazing value! A single bottle contains up to a 4-month supply. Compare this to other leading brands that require 2 capsules per serving, do not provide a 7500 mg strength dosage, and are not Certified USDA Organic. Our Organic Milk Thistle is a bargain not be found elsewhere!

80% SILYMARIN FLAVONOIDS: The "good stuff" in Milk Thistle is called Silymarin Flavonoids. The more Silymarin Flavonoids, the better the Milk Thistle! Our Organic Milk Thistle has been standardized to 80% Silymarin Flavonoids, which means that each capsules contains 200 mg of Silymarin Flavonoids from a 30:1 extract - the highest dosage available!

30:1 EXTRACT FOR MAXIMUM STRENGTH DOSAGE: Our Organic Milk Thistle is made from a potent, concentrated 30:1 extract. A 30:1 extract means that the herb itself has been condensed, so that 30 grams of the original herb are concentrated into a single gram. By using a 30:1 extract, we have created a powerful supplement that is 30X stronger than standard Milk Thistle capsules.
