How to Take It
Best taken in the morning
Contains Green Tea Leaf Extract, which is stimulating — keep it to the morning. What's in this absorbs poorly without a fat-containing meal — take it with one.
With a meal containing fat
NAC absorbs 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.
Keep it away from iron-rich meals
Space it a couple of hours from Iron
On the label
As a dietary supplement, take one capsule daily or as directed by a healthcare practitioner.
General guidance based on the ingredients, not a substitute for the label or your doctor.
