Bio-Magnesium is a complex of three different magnesium salts. Each tablet provides you with 200 mg of pure magnesium. The tablet contains a mixture of organically and inorganically bound magnesium contained in a matrix that causes the tablet to dissolve completely in less than two minutes - even in people with a low stomach acid content - where the magnesium content will be changed to a absorbable ion form providing a high absorption. Bio-Magnesium tablets are normally swallowed whole, but can also be chewed or dissolved in a glass of water. Bio-Magnesium need not necessarily to be consumed with a meal.
