Magnesium and Diabetics

Side Effects of Magnesium on Kidneys

Learn More

Low magnesium levels often occur in diabetics from excessive urination and low blood glucose levels 1 2. Magnesium glycinate is a better option for stabilizing magnesium levels in diabetics as gluconate is processed through the same pathways as glucose 1 2.

Warning

There is the possibility of allergic reactions from taking magnesium gluconate 1 2. These reactions often occur from one of the support materials in the supplement, rather than from magnesium gluconate itself 1 2. Magnesium glycinate can have this same effect 1 2.
