Donat Mg

Renowned for its extremely high magnesium content (>1000mg/L) and therapeutic digestive benefits. It is clinically proven to relieve constipation, heartburn, and magnesium deficiency while supporting metabolism and providing an excellent, bioavailable source of magnesium that absorbs faster than pills. Did I mention it was high in magnesium?

Very tough to find but it is out there in a few specialty stores and very available online.
