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
On the label
As a dietary supplement, take 1 capsule, 1-4 times daily, between 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.
