How to Take It
Take it anytime
Absorption is modest either way; taking it with carbohydrate-containing meals improves uptake.
With food
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
As a dietary supplement, take one (1) capsule one to three times daily, or as directed by your qualified healthcare professional.
General guidance based on the ingredients, not a substitute for the label or your doctor.
