Take it anytime

Take with plenty of water. Fiber binds other things in the gut, so give it a 1–2 hour gap either side.

With food
Keep it away from medication and mineral supplements

On the label

As a dietary supplement, mix one (1) scoop in 8 ounces of water 1 - 2 times daily.

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