The review of trials identifies positive effects of these nutrients on various outcome measures relating to insulin resistance and cardiovascular factors .
A majority of the trials found a positive effect of chromium on fasting plasma glucose .
Isoflavones were found to have a positive effect on insulin resistance and cardiovascular outcome measures , but only when combined with soy proteins .
Vitamin E is reported to reduce oxidative stress at levels of 200 mg day(-1 ) or more
The role of nutritional supplementation is of increasing interest with regard to ocular disease .
R and omised controlled trials have demonstrated the effectiveness of supplementation for age-related macular degeneration , and formulations are now being developed for use by people with diabetes and diabetic retinopathy .
The aim of this review was to synthesis e the evidence for use of nutritional supplementation in type 2 diabetes .
The potential role of alpha-lipoic acid , chromium , folic acid , isoflavones , magnesium , Pycnogenol , selenium , vitamin C , vitamin E , and zinc in the treatment of type 2 diabetes is discussed .
Magnesium and ascorbic acid supplementation in diabetes mellitus.
The effect of magnesium ( Mg ) and ascorbic acid ( AA ) supplementation on metabolic control was assessed in 56 outpatient diabetics . A 90-day run-in period was followed by two 90-day treatment periods , during which Mg ( 600 mg/day ) and AA ( 2 g/day ) were administered in a r and omized double-blind cross-over fashion . A decrease in systolic and diastolic blood pressure ( 132 + /- 3 vs. 138 + /- 4 and 77 + /- 2 vs. 82 + /- 2 mm Hg ; p < 0.05 ) was observed in insulin-dependent diabetes mellitus subjects during Mg supplementation . No beneficial effect of Mg supplementation was observed on glycemic control , lipids or blood pressure in non-insulin-dependent diabetes mellitus ( NIDDM ) subjects . AA supplementation improved glycemic control among NIDDM subjects and both fasting blood glucose ( 9.1 + /- 0.5 vs. 10.1 + /- 0.6 mmol/l ; p < 0.05 ) and HbA1c ( 8.5 + /- 0.3 vs. 9.3 + /- 0.3 % ; p < 0.05 ) improved . Beneficial effects of AA supplementation on cholesterol ( 5.9 + /- 0.2 vs. 6.2 + /- 0.2 mmol/l ; p < 0.05 ) and triglycerides ( 2.2 + /- 0.2 vs. 2.5 + /- 0.2 ; p < 0.05 ) were also observed in NIDDM subjects . The results suggest that high-dose AA supplementation may have a beneficial effect in NIDDM subjects on both glycemic control and blood lipids
