Fura-Mag/Interplexus is available by Ayush Herbs.

Fura-Mag supplies 107 mg. of elemental magnesium per capsule. Fura-Mag has an 80% absorption efficiency, compared with 30% absorption of most other formulations. The fumarate part of magnesium fumarate is a low molecular weight organic salt which is metabolized with great efficiency in the Krebs cycle, perhaps our most fundamental energy-releasing pathway.

High Absorption Magnesium

Dietary Supplement

The various mineral forms of magnesium are NOT all equally absorbed. Magnesium Glycinate and Magnesium Oxide only have about 25% absorption efficiency. The daily recommended allowance is calculated using 25-35% absorption. In contrast, magnesium fumarate, as used in Fura-Mag is much more readily utilized  by the body, approaching 85% absorption.
