Although the amino acid arginine is mostly used in sports nutrition supplements, it is also the main ingredient in Pro Argi-9 L Arginine, which claims to have numerous general health benefits. According to the official website for Pro Argi-9 L Arginine, the main mechanism of arginine is to increase your body's levels of nitric oxide, which helps dilate blood vessels, among other actions. The website also explains that you may experience additional benefits due to the inclusion of Pro Argi-9 L Arginine's other ingredients: citrulline, pomegranate, red wine extract, folic acid and several vitamins. You should consult a doctor before using this or any other supplements.

Possible IGF-1 Increase
ProArgi-9's main ingredient, the amino acid arginine, is often used by bodybuilders and strength-training athletes because it may have positive hormonal benefits. According to research published in the "Journal of Strength and Conditioning Research," the use of arginine significantly increased participants' levels of insulin-like growth factor 1, or IGF-1. IGF-1 is a hormone that is involved in muscle building and may promote increased muscle mass.Note that these hormonal changes occurred in conjunction with exercise, so if you are inactive you may not experience similar effects.
Possible Growth Hormone Increase
Another hormonal change uncovered in the research published in the "Journal of Strength and Conditioning Research" was a significant improvement in levels of growth hormone. As the name indicates, growth hormone is involved in growth and development and increases muscle mass.
Reduction of Blood Pressure
As the official website for Pro Argi-9 L Arginine explains, one major function of arginine is that it produces nitric oxide, which can dilate your blood vessels. One effect of this process, called vasodilation, is that it may improve blood flow. According to research from the journal "Cell Biochemistry and Function," arginine supplementation helped to reduce blood pressure thanks to the vasodilation. However, this research was performed in rats, so you may not experience the same results.
Reduced Muscle Soreness
If you engage in resistance training or other forms of strenuous exercise, ProAgri-9 L Arginine may be particularly beneficial for you. In addition to the possibility of improved muscle mass, thanks to the IGF-1 and growth hormone increases, this product may reduce muscle soreness, thanks to the citrulline it contains. Research published in the "Journal of Strength and Conditioning Research" found that supplementation of citrulline helped to reduce muscle soreness by 40 percent during the two days following exercise sessions.
