How to Take It
Take it anytime
What's in this absorbs poorly without a fat-containing meal — take it with one.
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 1 capsule daily with or after a meal or as directed by your healthcare professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
