How to Take It
Take it anytime
No evidence a formula this broad works better at any particular hour. 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 coffee, tea and dairy
Space it a couple of hours from Calcium, Manganese and Green Tea Leaf Extract
On the label
