Natrol L-Arginine -- 1000 mg - 50 Tablets

The amino acid L-Arginine has several major functions in the body, including as a precursor of NO. This chemical messenger plays a vital role in vasodilatation, relaxation of smooth muscle cells within arterial blood vessels. Dietary L-Arginine provides the nitrogen our bodies use to produce NO.

Because of L-Arginine’s potential role in vasodilatation, it may support healthy blood vessels. Emerging evidence suggests a role of L-Arginine in immune function. It is well known that the body uses more L-Arginine when it is under stress or injured. Further, L-Arginine is also used by the body to produce creatine which supports muscle protein synthesis.

People who are on blood pressure medication should monitor their blood pressure levels, or consult their physician before taking Arginine.

This supplement should be avoided by persons with glaucoma or herpes simplex unless otherwise prescribed by a physician.  Do not use if you have had a myocardial infarction or have established coronary artery disease.

If you have diabetes or have ever been diagnosed with cardiovascular disease, consult your healthcare practitioner before using this product. L-Arginine sometimes can reactivate latent herpes virus infections. Those with certain psychoses may experience worsened symptoms if they take L-Arginine supplements. Always take antioxidants with L-Arginine.
