Reviewed by Dr. Younghun Cho, PharmD
This product scores in the average range because while it is a cheap source of magnesium, its poor absorption and common digestive side effects make other forms superior for supplementation.
Pharmacist's Verdict
Nature Made Magnesium Oxide is an affordable supplement, but its poor absorption and high likelihood of causing diarrhea make it a less effective choice for correcting a deficiency compared to other forms like magnesium citrate or glycinate.
