Abstract Title:
Vitamin C for Type 2 Diabetes Mellitus and Hypertension.
Abstract:
It is suggested that supplementation of vitamin C reduces hyperglycemia and lowers blood pressure in hypertensives by enhacing the formation of prostaglandin E1 (PGE1), PGI2 (prostacyclin), endothelial nitric oxide (eNO), and restore essential fatty acid (EFA) metabolism to normal and enhance the formation of lipoxin A4 (LXA4), a potent anti-inflammatory, vasodilator and antioxidant. These actions are in addition to the ability of vitamin C to function as an antioxidant. In vitro and in vivo studies revealed that PGE1, PGI2 and NO have cytoprotective and genoprotective actions and thus, protect pancreaticβ and vascular endotheilial cells from the cytotoxic actions of endogenous and exogenous toxins. AA, the precursor of LXA4 and LXA4 have potent anti-diabetic actions and their plasma tissue concentrations are decreased in those with diabetes mellitus and hypertension. Thus, vitamin C by augmentingthe formation of PGE1, PGI2, eNO, LXA4 and restoring AA content to normal may function as a cytoprotective, anti-mutagenic, vasodilator and platelet anti-agregator actions that explains its benefical action in type 2 diabetes mellitus and hypertension.
