How to Take It
Best taken in the evening
The Magnesium in it is what pulls this toward the evening. Take it with food — the potassium in it is what makes this kind of product feel nauseating on an empty stomach.
With food
Space it a couple of hours from Iron and Calcium
Label directs 2 servings — keep one for the evening
