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.
With a meal containing fat
Space it a couple of hours from Iron and Calcium
On the label
Take one tablet daily, during or immediately after a meal, or as directed by a healthcare professional
General guidance based on the ingredients, not a substitute for the label or your doctor.
