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 and potassium in it are what makes this kind of product feel nauseating on an empty stomach.

With food

On the label

Adults, as a dietary supplement, take 1 tablet daily, preferably before meals.

The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.

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