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 vitamins D and E in it absorb poorly without one.
With a meal containing fat
Rhodiola rosea does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Space it a couple of hours from Iron and Calcium
