How to Take It
Best taken in the evening
The Magnesium in it is what pulls this toward the evening. Take it with a meal containing fat — the vitamin D in it absorbs poorly without one.
With a meal containing fat
Keep it away from high-oxalate foods like spinach
Space it a couple of hours from Iron and Zinc
On the label
Individual needs may vary. Start out with approximately 1 teaspoon (2.5 g) daily and gradually increase to approximately 3 teaspoons (7.5 g) daily. For best results, divide the daily amount into 2 or 3 portions per day, taken with or without food.
General guidance based on the ingredients, not a substitute for the label or your doctor.
