Magnesium Salts: A Formulator’s Overview

Why the choice of magnesium salt changes elemental content, dose size and format.

Magnesium is supplied as many different salts and chelates, and each carries a different proportion of elemental magnesium. That proportion drives how much material is needed per serving, which in turn affects capsule count or tablet size.

Chelated forms such as magnesium glycinate are widely used in supplements, while other salts are chosen for cost, density or format. Some magnesium compounds are not supplements at all: magnesium stearate is an excipient used as a lubricant in manufacturing.

When requesting a quotation, specify the salt, the elemental magnesium target per serving and the intended format. This lets the supplier confirm grade, density and feasibility up front.

We keep magnesium glycinate as its own product record and treat the wider magnesium range as a family, adding individual salts as they are confirmed.
