How to Take It
Take it anytime
Poorly absorbed on its own — take with a fatty meal, ideally in a formulation with black pepper or a lipid carrier.
With a meal containing fat
On the label
As a dietary supplement, take 1 capsule, 1-3 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.
