Dietary L-Arginine Supplementation Reduces White Fat Gain and Enhances Skeletal Muscle and Brown Fat Masses in Diet-Induced Obese Rats

Previous studies showed that dietary L-arginine supplementation decreased white fat mass in genetically obese rats. This study tested the effectiveness of L-arginine in diet-induced obesity.

The arginine treatment reduced the relative weights of white fat pads by 30% and enhanced those of soleus muscle by 13%, extensor digitorum longus muscle by 11%, and brown fat by 34% compared with control rats.

Thus, dietary arginine supplementation shifts nutrient partitioning to promote muscle over fat gain and may provide a useful treatment for improving the metabolic profile and reducing body white fat in diet-induced obese rats. [Source]

Dietary l-arginine supplementation increases muscle gain and reduces body fat mass in growing-finishing pigs

Obesity in humans is a major public health crisis worldwide. In addition, livestock species exhibit excessive subcutaneous fat at market weight. However, there are currently few means of reducing adiposity in mammals. This study was conducted with a swine model to test the hypothesis that dietary l-arginine supplementation may increase muscle gain and decrease fat deposition.

The arginine treatment enhanced (P < 0.05) longissimus dorsi muscle protein, glycogen, and fat contents by 4.8, 42, and 70%, respectively, as well as muscle pH at 45 min post-mortem by 0.32, while reducing muscle lactate content by 37%.

These results support our hypothesis that dietary arginine supplementation beneficially promotes muscle gain and reduces body fat accretion in growing-finishing pigs. The findings have a positive impact on development of novel therapeutics to treat human obesity and enhance swine lean-tissue growth. [Source]

Blood pressure and metabolic changes during dietary l-arginine supplementation in humans

Dietary l-arginine supplementation has been proposed to reverse endothelial dysfunction in such diverse pathophysiologic conditions as hypercholesterolemia, coronary heart disease, and some forms of animal hypertension. In particular, chronic oral administration of l-arginine prevented the blood pressure rise induced by sodium chloride loading in salt-sensitive rats.

To investigate the effects of l-arginine–rich diets on blood pressure and metabolic and coagulation parameters we performed a single-blind, controlled, crossover dietary intervention in six healthy volunteers.

These results indicate that a moderate increase in l-arginine significantly lowered blood pressure and affected renal function and carbohydrate metabolism in healthy volunteers. [Source]

Vascular effects of dietary l-arginine supplementation

The vascular endothelium is acknowledged to play an important role in vascular physiology. Attention has focused on endothelial production of nitric oxide as a key element in many of the processes associated with the development of atherosclerosis. l-arginine is the substrate for the enzyme nitric oxide synthase (NOS), which is responsible for the endothelial production of nitric oxide. Therefore, many investigators have been interested in whether dietary l-arginine supplementation can augment nitric oxide production and thereby improve vascular health.

Although results of oral l-arginine supplementation in hypercholesterolemic animals have generally shown beneficial effects, the data in humans are varied, possibly because of small sample sizes and brief periods of study. Long-term randomized clinical trials are needed to more definitively address whether oral l-arginine supplementation could be advantageous for vascular health. [Source]
