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
Label directs 2 servings — keep one for the evening
On the label
Adults Take 2 tablets once a day, or as prescribed by a health professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
