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 and Zinc
On the label
Adults: Take 1 to 3 caplets daily with a meal. Take a few hours before or after taking other medications or natural health products
General guidance based on the ingredients, not a substitute for the label or your doctor.
