Overview
Not a blended mineral formula, this is a magnesium oxide tablet that the maker calls the most concentrated form of magnesium. It is unflavored and sold as a bottle of tablets for adults.
One mineral in one tablet makes the label clear, and the listed concentration makes it easy to compare against other magnesium products. The limitation is that the listing gives no serving size, and magnesium oxide is the form most likely to affect digestion.
Who it's for
A person who has been advised to raise magnesium and prefers a single-ingredient tablet in a large bottle. Anyone with kidney problems, on prescription medication, or avoiding gelatin should check with a clinician and the label before use.
Pros and cons
- Single-ingredient magnesium tablet
- Concentration clearly stated
- Alcohol free and gluten free
- Gelatin listed as an allergen
- Serving size not listed
- Can cause loose stools in some
Performance notes
Magnesium oxide holds a large share of elemental magnesium by weight but is absorbed less readily than other forms. The amount reaching the body depends on dose and meal timing, and larger doses are more likely to affect digestion.
