How to Take It
Best taken in the morning
The Tyrosine in it is what pulls this toward the morning. Take it with a meal containing fat — the vitamin E in it absorbs poorly without one.
With a meal containing fat
Tyrosine 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.
Keep it away from protein-heavy meals
Space it a couple of hours from Iron and Calcium
Label directs 2 servings — keep one for the morning
On the label
Take 2 capsules two times daily or as recommended by your health professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
