Features and benefits

  • One tablet contains the recommended daily intake (RDI) for magnesium.
  • Combines magnesium with co-factors for improved absorption and utilisation.


How it works

Magnesium is essential for many cellular functions, particularly those functions involved in energy production, and for the normal functioning of muscle and nerve tissue. Signs of low magnesium levels can include fatigue, mental confusion, irritability, muscle cramps, problems with nerve conduction and muscle contraction and predisposition to stress.


If the blood is low in magnesium it takes it from the muscles and without enough magnesium in muscles they stiffen up or contract. The result may be painful cramps, irritability, twitching or even tremors. Sufficient magnesium helps all muscles in the body to function optimally.


The other nutrients present in Bio Magnesium assist with the utilisation of magnesium in the body. Vitamin B6 is an important co-factor, working with magnesium in many enzyme systems in the body. Studies have shown that combining B6 and magnesium can help to reduce PMS symptoms.
