How to Take It
Take it anytime
Fat-soluble — take with a meal containing fat for better absorption. Time of day doesn't matter.
With a meal containing fat
Keep it away from medication and mineral supplements
On the label
Take four (4) tablets with a glass of water, preferably on an empty stomach.
The label says to take it on an empty stomach, but what's in this absorbs poorly without dietary fat. Take it with a meal that has some.
General guidance based on the ingredients, not a substitute for the label or your doctor.
