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

Take one (1) capsule once or twice daily, with or without food, or as recommended by a healthcare practitioner.

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

Sources & Scoring

Nutrient data (RDA, UL, and safety thresholds) sourced from the NIH Office of Dietary Supplements and the National Academies Dietary Reference Intakes (DRI).

This is not medical advice. Consult a healthcare provider before making changes to your supplement routine.

The score analyzes what's on the label: ingredient doses vs. studied ranges, chemical forms, evidence levels, and known interactions. It does not verify label accuracy or test for contaminants — for that, look for third-party certifications like USP or NSF.
