How to Take It

Best taken in the evening

Calming herb — used in the evening. Take it with food — the zinc 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

Adults take 2 tablets daily with a beverage. May be taken any time of day, even on an empty stomach.

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