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.
On the label
Adults take four (4) capsules daily. For best utilization, take with food. Do not exceed recommended dose.
General guidance based on the ingredients, not a substitute for the label or your doctor.
