During subgroup analysis , a more beneficial effect of magnesium supplementation was observed in diabetic subjects with hypomagnesaemia .
CONCLUSIONS Magnesium supplementation can produce a favourable effect on FPG , HDL , LDL , TG and SBP .
BACKGROUND Cardiovascular disorders remain the leading cause of death in type 2 diabetic patients .
In the present study , a systematic review and a meta- analysis of r and omised controlled trials ( RCTs ) were conducted aim ing to evaluate the effect of magnesium supplementation on  type 2 diabetes ( T2D ) associated cardiovascular risk factors in both diabetic and nondiabetic individuals .
Oral magnesium supplementation improves insulin sensitivity in non-diabetic subjects with insulin resistance. A double-blind placebo-controlled randomized trial.
OBJECTIVE Although hypomagnesemia reduces insulin sensitivity , benefits of magnesium supplementation to non-diabetic insulin resistant subjects has not been established . Our purpose was to determine whether oral magnesium supplementation with magnesium chloride ( MgCl2 ) 2.5 g daily modify insulin sensitivity in non-diabetic subjects . MATERIAL AND METHODS This study was a 3 months r and omized double-blind placebo-controlled trial . Apparently healthy subjects were eligible to participate if they had insulin resistance ( HOMA-IR index equal or greater than 3.0 ) and hypomagnesemia ( Serum magnesium levels equal or lower than 0.74 mmol/l ) . Subjects were r and omized to receive either , MgCl2 2.5 g daily or placebo by 3-months . RESULTS At baseline there were not significant anthropometric or laboratory differences between both groups . At ending of the study , magnesium-supplemented subjects significantly increased their serum magnesium levels ( 0.61 + /- 0.08 to 0.81 + /- 0.08 mmol/l , p<0.0001 ) and reduced HOMA-IR index ( 4.6 + /- 2.8 to 2.6 + /- 1.1 , p<0.0001 ) , whereas control subjects did not ( 0.62 + /- 0.08 to 0.61 + /- 0.08 mmol/l , p=0.063 and 5.2 + /- 1.9 to 5.3 + /- 2.9 , p=0.087 ) . CONCLUSIONS Oral magnesium supplementation improves insulin sensitivity in hypomagnesemic non-diabetic subjects . Clinical implication s of this finding have to be established
