How to Take It
Best taken in the evening
The Magnesium in it is what pulls this toward the evening. Calcium is easier on the stomach taken with food.
With food
Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron and Zinc
On the label
As a dietary supplement, take 1⁄2 heaping teaspoon in 8 - 10 oz. of liquid daily, between meals, or as directed by a healthcare practitioner.
The label says to take it on an empty stomach. What's in this one sits better with food, and you give up little by taking it that way.
General guidance based on the ingredients, not a substitute for the label or your doctor.
