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 high-oxalate foods like spinach
Space it a couple of hours from Iron

On the label

One tablet daily, with food.
