How to Take It
Take it anytime
Poorly absorbed on its own — take with a fat-containing meal.
With a meal containing fat
On the label
As a dietary supplement, take 2 capsules, 1-2 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.
