L arginine is an amino acid found in many protein high foods. Despite having many functions its main role is to serve is as a nitric oxide booster – beneficial particularly to the cardiovascular system and the healthy functioning of blood vessels. We also need it for protein syntheses, wound healing and removing urea and nitrogen waste from the body.
According to some studies supplementation with l-arginine can improve the function of blood vessels and improve coronary blood flow. Additionally it lowers blood pressure and can even reduce angina and other symptoms in people with heart disease. It has been known to be used as additional treatment in heart condition patients.
L- arginine supplements claim to help with erectile dysfunction. Since it is a precursor of nitric oxide responsible for vasodilation it is claimed to improve blood flow also it that area in the body.
In addition to the above, l-arginine has the ability to fight free radicals, and potentially signal muscle cells, release growth hormone as well as remove bad cholesterol.
How would it enhance muscular development? It has an impact on insulin, which is an anabolic hormone. Also, if you can dilate your arteries, you enhance blood flow to the muscles and enhance nutrient delivery and waste product removal. More nutrients = better development.
L-arginine takes part in fat metabolism and regulating salt levels in the body.
Despite several studies confirming the effectiveness of l-arginine in treating certain conditions other studies such as the one conducted by researchers at Stanford University found that arginine doesn’t help people with arterial issues and can even make the condition worse. Claims were made that given to heart patients, l-arginine increases mortality rates. It is therefore logical to assume that it shouldn’t be taken as a supplement without consulting your doctor.
L-Arginine supplements have been shown to worsen asthma symptoms and increase lung inflammation.
Also, some studies are skeptical about the erectile dysfunction improvement or muscle growth as benefits of l-arginine.
In large doses l-arginine has been known to cause headaches, nausea, diarrhea and weakness.
So far the studies aren’t really conclusive and supplementation should be approached with caution. If you are serious about your healthy lifestyle and training, there is nothing wrong with trying natural supplements such as l-arginine, just remember to buy from trustworthy sources and consult a physician especially if you suffer from any health conditions.
