How to Take It
Best taken in the morning
The Vitamin B6 in it is what pulls this toward the morning. What's in this absorbs poorly without a fat-containing meal — take it with 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
On the label
Take 2 capsules daily between meals. Store in a cool, dry place after opening.
