How to Take It

Best taken in the evening

The Magnesium in it is what pulls this toward the evening. What's in this absorbs poorly without a fat-containing meal — take it with one.

With a meal containing fat
Space it a couple of hours from Iron and Calcium

On the label

Adult use: Take 3 capsules daily with food, or as recommended by a nutritionally-informed physician.
