How to Take It
Take it anytime
Take it with a meal containing fat — the vitamin E in it absorbs poorly without one.
With a meal containing fat
ALA does better on an empty stomach, but something else in this bottle needs food. Taking the whole product with a meal is the better trade — an upset stomach is why most people stop.
Space it a couple of hours from Iron and Calcium
On the label
2 capsules per day or as recommended by your health care professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
