How to Take It
Best taken in the morning
Contains Green Tea Leaf Extract, which is stimulating — keep it to the morning. Take it with a meal containing fat — the vitamin E in it absorbs poorly without 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
One tablet daily, during or immediately after a meal, or as directed by a healthcare professional
General guidance based on the ingredients, not a substitute for the label or your doctor.
