Preventing recurrent hypomagnesaemia: oral magnesium glycerophosphate

Evidence strengths and limitations

The evidence identified was of low quality. The results in these 3 patients may not be representative of what would occur in most patients with hypomagnesaemia or in patients with hypomagnesaemia resulting from other conditions. The lack of a control group means that it is not possible to compare outcomes across different oral magnesium preparations, different routes of administration, or without magnesium supplementation.
