Other Ingredients (3)
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.
Rice ConcentrateAnti-caking
A rice-derived blend used as a natural flow agent and anti-caking aid
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
As a dietary supplement, take one capsule three times per day with water before meals.
The label says to take it on an empty stomach, but what's in this absorbs poorly without dietary fat. Take it with a meal that has some.
General guidance based on the ingredients, not a substitute for the label or your doctor.
