How to Take It
Best taken in the morning
Bisglycinate is the gentle form — most people tolerate it on an empty stomach, which is exactly where it absorbs best. Vitamin C may help absorption.
On an empty stomach
Keep it away from coffee, tea and dairy
Space it a couple of hours from Calcium, Zinc, Magnesium, Manganese and Green Tea Leaf Extract
