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
Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron and Zinc

On the label

Mix 1 scoop with at least 8 ounces of water one to two times daily or as recommended by your health-care practitioner.

General guidance based on the ingredients, not a substitute for the label or your doctor.
