How to Take It
Best taken in the morning
Contains Rhodiola rosea, 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 protein-heavy meals
Space it a couple of hours from Iron and Calcium
On the label
Take 2 capsules, 1-2 times daily; best taken with food.
