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

On the label

Adults, take 2 softgels daily with water and a meal.

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