Other Ingredients (2)

Rice FlourFiller

Rice-based ingredients carry risk of inorganic arsenic contamination (FDA and Consumer Reports). Rice accumulates arsenic from soil at higher rates than other grains. Used as a cheap filler — adds nothing beneficial.

GelatinCapsule

Protein derived from collagen, used in traditional capsule shells

How to Take It

Take it anytime

Silymarin barely dissolves in water — a fat-containing meal meaningfully improves absorption.

With a meal containing fat
Split into 3 doses across the day

On the label

Take 1 capsule 3 times daily, as a dietary supplement, or as directed by a physician.

General guidance based on the ingredients, not a substitute for the label or your doctor.
