L-arginine has been proven by many scientific studies to help the human body in many ways. L-arginine is involved in the production of a variety of enzymes, hormones, and structural proteins.
Studies have shown that L-arginine, through its versatile metabolic and physiological pathways, can improve many functions of the body. It enhances sexual performance in males. It protects from – as well as heals – gastric ulcers induced by various agents. The demonstrated anti-aging benefits of l-arginine show promises greater than any pharmaceutical or nutraceutical agent ever previously discovered (7)!
The Top 5 Proven Health Benefits of L-arginine
1. Improves Heart Health
Some of the ways that L-arginine improves cardiovascular health include: preventing high blood pressure, improving blood flow in people with clogged arteries (coronary artery disease), lowering high cholesterol, helping to relieve congestive heart failure, improving stamina, and reducing symptoms associated with cut-off blood flow from the heart to the limbs (called claudication).
It’s also commonly used for treating chest pains (angina pectoris) because of the effects of nitric oxide preventing blood clots (thrombosis) that cut off blood supply.
2. Helps With Erectile Dysfunction and Libido
L-arginine increases blood flow to the genitals in both men and women, leading to an increased libido. In men, increased blood flow to the penis can result in more frequent and sustained erections. L-arginine is often suggested for men suffering from erectile dysfunction. In women, increased blood flow to the genitals can lead to increased sexual arousal and orgasm. A healthy libido plays an important role in conception (1).
3. Improves Immune Function
L-arginine is used commonly with omega-3 fish oils and other supplements for reducing the risk for infections. It can help heal wound infections. It also helps shorten the recovery time from cancer, illness, or surgery. The human immune system’s protective lymphocytes and T-cells depend on arginine for defending the body (2).
4. Supports Normal Blood Pressure
The most recent research suggests that L-arginine may lower blood pressure. Some people take L-arginine because it’s believed to relax and open your arteries, which might help lower blood pressure (3).
5. Stimulates Growth Hormone Production (4)
Exercise is also a very potent stimulator of human growth hormone release and there is considerable research documenting the dramatic growth hormone rise (6). At rest oral L-arginine ingestion will enhance the growth hormone response and the combination of arginine plus exercise increases growth hormone, but this increase may be less than seen with exercise alone.
6. Improves Fertility
According to Natural Fertility, Research has found that taking a l-arginine supplement daily can increase sperm production in men. In the study, the effects were noticeable 6-8 weeks from the start of supplementation. L-arginine may also improve the motility of sperm, thus increasing the chance of conception in couples suffering from low sperm motility. Where IVF is used, l-arginine can be used to improve the quality of sperm, increasing the the chance of achieving a fertilized egg.
L-arginine improves the production of cervical mucous - the increased blood flow to the reproductive organs can aid in the production of cervical mucous. Abnormal mucous production contributes to the challenges faced by around 1 in 20 women dealing with fertility issues. Some women do not produce enough cervical mucous, and others produce a mucous that is too thick for sperm to travel through. L-arginine can encourage better production of cervical mucous through improved blood flow.
