Blackmores Bio Magnesium helps to minimise low magnesium states. Many adolescent girls, women and men may not get enough magnesium in their diets. Deficiency is most prevalent in men and women aged 45 plus. If the body is low in magnesium it is forced to take it from the muscles and without enough magnesium in muscles they stiffen up or contract at liberty. The result may be painful cramps, irritability, twitching or even tremors. Sufficient magnesium found in Blackmores Bio Magnesium helps all muscles in the body to function optimally.


Features and benefits

  • Combines magnesium with co-factors for improved absorption and utilisation
  • Contains magnesium from two different sources, magnesium oxide (which is the most concentrated source of elemental magnesium) and magnesium phosphate

How it works

Magnesium is essential for the electrical activity of nerves and muscle, and is indicated to relieve painful cramps (including menstrual cramps), twitching and tremors. Together with calcium, magnesium plays an integral role in tooth and bone hardness.

Other nutrients present in Bio Magnesium also assist muscle function and include vitamins C and D (low intake has been associated with muscle fatigue), vitamin B6 and the mineral manganese which is involved in active phosphate transfer processes to provide muscle energy.
