How to take it

With a meal containing fat

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 iron-rich meals
Space it a couple of hours from Iron
Label directs 2 servings — keep one for the morning

On the label

Take 3 capsules two times daily or as recommended by your health professional.
