How to Take It
Best taken in the evening
The Magnesium in it is what pulls this toward the evening. Take it with a meal containing fat — the vitamin D in it absorbs poorly without one.
With a meal containing fat
Space it a couple of hours from Iron and Calcium
On the label
For adults, take one (1) vegetarian capsule daily, preferably with a meal.
General guidance based on the ingredients, not a substitute for the label or your doctor.
