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
Label directs 2 servings — keep one for the morning

On the label

Take two capsules twice daily, or as directed by your healthcare practitioner.

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