How to Take It
Take it anytime
Silymarin barely dissolves in water — a fat-containing meal meaningfully improves absorption.
With a meal containing fat
NAC does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
On the label
Take 2 capsules per day or as directed by your healthcare professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
