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 vitamins A, D and E in it absorb poorly without one.

With a meal containing fat
Keep it away from coffee, tea and dairy
Space it a couple of hours from Magnesium, Manganese and Green Tea Leaf Extract

On the label

Adults, take one softgel daily with food.

General guidance based on the ingredients, not a substitute for the label or your doctor.
