Vitamin C is wonder pill -long term use lowers blood sugar and High BP in diabetics ,finds a new study.
Australian researchers in a study have found out that Vitamin C supplementation for 4 months controls Blood sugar and High BP in patients of Type 2 Diabetes .The study has appeared in Journal Diabetes, Obesity and Metabolism.
Diabetes is increasing in epidemic proportions worldwide. In India alone, more than 68 million people have Diabetes. Vitamin C is a major water‐soluble antioxidant that decreases cellular and tissue oxidative stress.Oxidative stress has been proposed as an important underlying causative agent in the pathogenesis of insulin resistance and hyperglycaemia‐induced diabetes complications. Furthermore, some studies have shown that supplementation with Vitamin C can improve whole body insulin action in individuals with type 2 diabetes (T2D).

Dr Mason SA, at School of Exercise and Nutrition Sciences, Institute for Physical Activity and Nutrition, Deakin University, Australia and associates conducted a randomized cross-over study to investigate how ascorbic acid (AA) supplementation influences postprandial glucose responses under free-living conditions in individuals with type 2 diabetes.A secondary aim was to investigate the effect of Vitamin C supplementation on blood pressure.
Researchers performed a study of 31 individuals with type 2 diabetes with 4 months supplementation with oral AA (2 × 500 mg/d) or placebo. In addition, they determined the effect of AA supplementation on blood pressure. Participants wore continuous glucose monitors for 48 hours and consumed standardized meals pre‐ and post‐supplementation. Measurements included postprandial glucose incremental areas under the curve (iAUC), duration of day in hyper‐ and hypo‐glycaemia status, average 24‐hour and daily postprandial glucose concentrations, HbA1c, insulin, blood pressure (BP) and oxidative stress (F2‐isoprostanes).

Following AA supplementation, significant decreases were observed in daily postprandial glucose iAUC , in duration of day with hyperglycaemia and postprandial hyperglycaemia , in average 24‐hour glucose and daily postprandial glucose concentrations, in systolic and diastolic blood pressures and in a specific fraction of free plasma F2‐isoprostanes as compared to placebo.Four months of Vitamin C supplementation seemed resulting in improved postprandial and 24-hour glycaemia and decreased blood pressure (BP) compared to placebo among individuals with type 2 diabetes.
The investigators reached a conclusion that individuals with type 2 diabetes experienced improved postprandial blood sugar and 24‐hour glycaemia and decreased BP after 4 months of AA supplementation as compared to placebo. These findings offer evidence for the proposed use of Vitamin C as an adjunct therapy to improve glycaemic and BP control in individuals with type 2 diabetes.
