Supports gastrointestinal health. Hypoallergenic. Gluten and casein free. Capsules are plant based. Ultra Tested. Milk thistle consists of three potent liver protective flavonoids: silybin, silydianin and silychristin. Collectively these are known as silymarin. To be effective, milk thistle products must be standardized to contain this active blend. Kirkman's milk thistle is standardized to contain 80% silymarin. Recent research has indicated that silymarin helps to protect against the depletion of glutathione in liver cells.Dietary Considerations Wheat Free Dairy/ Milk Free Gluten Free Soy Free Yeast Free Sugar Free Starch Free Preservative Free Corn Free Free of Artificial Colors/Flavors Egg Free Shellfish FreeSuggested UseOne to two capsules daily or as directed by a physicianServing Size:1 Capsule Servings Per Container: 100 Amount Per Serving Calcium (from DiCalcium Phosphate) 45 mg Phosphorus (from Dicalcium Phosphate) 35 mg Milk Thistle (Silybum marianum)(fruit) Extract, containing Silymarin 100 mg Other IngredientsVegetarian Capsule (hypromellose and water), Silicon Dioxide, Magnesium Stearate (plant based)Warnings Free of: Sugar, starch, soy, wheat, casein, gluten, mikl, corn, egg, preservatives, yeast, gelatin, flavorings, colorings, peanuts, tree nuts or fish Store in a cool dry place and tighly capped.
