How to Take It

Best taken in the morning

The Dimethylaminoethanol in it is what pulls this toward the morning. 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.

On the label

2 tablets 1 to 2 times daily with meals. A healthy diet rich in essential fatty acids, along with adequate hydration, is essential for healthy skin. We recommend drinking a minimum of 8 glasses of pure water daily.

General guidance based on the ingredients, not a substitute for the label or your doctor.
