How to Take It
Take it anytime
What's in this absorbs poorly without a fat-containing meal — take it with one.

ALA 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.
Split into 3 doses across the day
On the label
Take 2 capsules three times daily or as recommended by a health-care practitioner.
General guidance based on the ingredients, not a substitute for the label or your doctor.
