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 vitamins D and K in it absorb poorly without one.

Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron and Zinc
Label directs 1.33 servings — keep one for the evening
On the label
