How to Take It

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

Dissolve 1 level scoop (~7 grams) with 8 oz. of water or non-carbonated beverage, or as recommended by a nutritionally informed physician.

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