How to Take It
Best taken in the morning
Contains Caffeine, which is stimulating — keep it to the morning. Take it with a meal containing fat — the vitamin D in it absorbs poorly without one.
With a meal containing fat
On the label
As a dietary supplement, take 2 capsules daily, preferably with a meal or as directed by a healthcare practitioner.
General guidance based on the ingredients, not a substitute for the label or your doctor.
