Microcrystalline CelluloseBinder
Plant-derived cellulose used as a binder and filler in supplements
Capsule ShellCapsule
Generic capsule shell where the label does not specify the material. Common materials are hypromellose (HPMC) for vegetarian capsules and gelatin for traditional capsules — both are GRAS-listed and safe. Fish gelatin and pullulan variants also exist.
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 three times daily with food or water.
General guidance based on the ingredients, not a substitute for the label or your doctor.
