Magne B6


Magne B6 is a drug intended to restore the amount of magnesium in the body.  Normal levels of magnesium are important for the maintenance of heart and nervous system function. Pyridoxine (vitamin B6), one of the drug’s main ingredients, participates in various metabolic processes, and in regulating metabolism of the nervous system, in particular.

Low levels of magnesium are the evidence of magnesium deficiency, also known as hypomagnesemia. It may cause fatigue or muscle weakness, mental numbness and lack of emotion. Scientists have suggested that deficiency may also cause anxiety and raise blood pressure.


Magnesium deficiency (might be in combination with other deficiencies) with increased irritability, sleep disorders, stomach cramps, palpitations, fatigue, pain and muscle cramps or tingling sensation.
