How to Take It
Best taken in the morning
The Vitamin B5 in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamin A in it absorbs poorly without one.
With a meal containing fat
Space it a couple of hours from Iron and Calcium
Label directs 2 servings — keep one for the morning
On the label
