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
Space it a couple of hours from Iron and Calcium
On the label
Take 1 well rounded teaspoon (3.5g) up to 3 times a day, stirred into a cup of boiling water (or herbal tea) until it dissolves. Add honey to taste. Do not exceed recommended daily intake. Food supplements should not be used as a substitute for a varied and balanced diet and healthy lifestyle.
General guidance based on the ingredients, not a substitute for the label or your doctor.
