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
Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron
On the label
