The effect of oral L-arginine supplementation on fasting glucose, HbA1c, nitric oxide and total antioxidant status in diabetic patients with atherosclerotic peripheral arterial disease of lower extremities.

Abstract

Oral two-month supplementation with L-arginine (3 x 2 g/day) had no effect on fasting glucose and HbA1 level in diabetic patients with atherosclerotic peripheral arterial disease of lower extremities at Fontaine's stage II. The supplementation of L-arginine led to substantial increase in NO concentration and TAS level in these patients, suggesting its indirect antioxidative effect.
