For instance, in Drenthen et al.’s [52] study on 14 subjects with type 2 diabetes and insulin treatment, daily supplementation with 360 mg of magnesium from 150 mL magnesium gluconate solution did not modify insulin dose (p = 0.869) or HbA1c (p = 0.851) compared to placebo [52]. Here, INS is linked to type 2 diabetes mellitus.
