How to Take It

Take it anytime

No evidence a formula this broad works better at any particular hour. Take it with food — the niacin in it is what makes this kind of product feel nauseating on an empty stomach.

With food
Space it a couple of hours from Iron and Calcium

On the label

Take 2 VegCaps daily with a meal or glass of water. Use only as directed.

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