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 .
Effects of oral magnesium supplementation on insulin sensitivity and blood pressure in normo-magnesemic nondiabetic overweight Korean adults.
BACKGROUND AND AIM Little is known about the effect of magnesium on insulin sensitivity and BP in healthy individuals . Therefore , we investigated whether magnesium could improve insulin sensitivity and blood pressure ( BP ) in normo-magnesemic nondiabetic overweight adults . METHODS AND RESULTS In a double-blinded , placebo-controlled , r and omized trial , a total of 155 participants ( BMI > or = 23 kg/m(2 ) ) received either 12.3 mmol ( 300 mg ) of elemental magnesium in the form of magnesium oxide ( n=75 ) or placebo ( n=80 ) each day for 12 weeks , constituting the intent-to-treat population . A repeated- measures ANOVA was used to evaluate the between-group changes in variables during the study . The baseline characteristics between the intervention and control groups were similar . There were no significant differences between the groups in the pattern of change of the homeostasis model assessment insulin resistance index , BP over time during the 12-week study . In subgroup analysis , magnesium supplementation ( n=8 , 27 , and 24 , respectively ) lowered BP much more than placebo ( n=16 , 29 , and 25 , respectively ) in those subjects whose systolic BP > or = 140 mmHg , diastolic BP 80 - 90 mmHg , and diastolic BP > or = 90 mmHg at the start of the study ( P=0.016 , 0.043 , and 0.023 , respectively ) ; in comparison , those subjects whose initial BP reading was low at baseline did not show a change in BP . No significant adverse events related to magnesium supplementation were recorded . CONCLUSIONS These results suggested that magnesium supplementation does not reduce BP and enhance insulin sensitivity in normo-magnesemic nondiabetic overweight people . However , it appears that magnesium supplementation may lower BP in healthy adults with higher BP
