How to Take It

Best taken in the evening

Magnesium citrate pulls water into the bowel — mildly laxative at higher doses. Evening suits that; split the dose or switch to glycinate if it's too much.

With or without food
Space it a couple of hours from Iron and Calcium
Label directs 3 servings — keep one for the evening

On the label

As a dietary supplement, take 1 capsule three times daily, or as directed by a healthcare practitioner.

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