How to take it

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.
