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 Calcium, Magnesium, Manganese and Green Tea Leaf Extract

On the label

2 tablets daily with meals.

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

Nutrient data (RDA, UL, and safety thresholds) sourced from the NIH Office of Dietary Supplements and the National Academies Dietary Reference Intakes (DRI).

This is not medical advice. Consult a healthcare provider before making changes to your supplement routine.
