Improve blood flow
Arginine helps to relax and dilate blood vessels, which in turn allows for better blood circulation throughout the body. This increased blood flow can be beneficial for those who have cardiovascular problems or who are trying to improve their cardiovascular health.
Additionally, arginine can help to increase nitric oxide levels in the body, which also helps to improve blood flow. This helps to reduce inflammation and can be helpful in treating conditions like arthritis.
Enhance sexual health
A recent study has shown that the amino acid arginine may improve sexual function in men. The researchers looked at the effect of arginine on men with erectile dysfunction. The men were given either a placebo or 5 grams of arginine per day. After four weeks, the men who took arginine had better sexual function than those who took the placebo. (3)
Arginine may improve blood flow to the penis, which can lead to better erections. It may also help to relax the blood vessels, which can improve blood flow and cause firmer erections.
