How to Take It
Best taken in the morning
Contains Rhodiola rosea, which is stimulating — keep it to the morning. What's in this is easier on the stomach taken with food.
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.
On the label
Adults and children 16 and over take 1 capsule daily. Do not exceed recommended daily intake.
General guidance based on the ingredients, not a substitute for the label or your doctor.
