How to Take It
Best taken in the morning
Contains Ilex paraguariensis leaf, which is stimulating — keep it to the morning. Take it with food — the zinc in it is what makes this kind of product feel nauseating on an empty stomach.
With food
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
