How to Take It

Best taken in the morning

Contains Green Tea Leaf Extract, which is stimulating — keep it to the morning. What's in this absorbs poorly without a fat-containing meal — take it with one.

With a meal containing fat
Keep it away from iron-rich meals
Space it a couple of hours from Iron and Calcium

On the label

Take 6 capsules first thing in the morning or split into 2 doses, in the morning and later in the day.

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