How to Take It
Best taken in the evening
The Glycine in it is what pulls this toward the evening. Fiber is easier on the stomach taken with food.
With food
Arginine 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 medication and mineral supplements
Label directs 2 servings — keep one for the evening
On the label
Directions: Take two tablets two times daily or as directed by your healthcare practitioner.
General guidance based on the ingredients, not a substitute for the label or your doctor.
