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.
Magnesium StearateLubricant
A salt of stearic acid used as a lubricant in tablet and capsule production
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
1 capsule 3–6 times per day with meals or as directed by a health professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
