Key Benefits

• Pharmaceutical grade L-Arginine for quality you can trust.

• Provides a key amino acid used in protein synthesis.

NOW Foods L-Arginine is crafted to high standards in the USA, using globally sourced ingredients. Each bottle is made from 100% post-consumer recycled resin, so you can feel good about your choice every day.

L-Arginine is one of the 20 essential amino acids which are the building blocks of all natural protein. When l-arginine is ingested it gets converted into a chemical called nitric oxide (NO), which causes blood vessels to open wider for improved blood flow. It can also stimulate the release of insulin and is involved primarily in urea metabolism in the liver and excretion in the kidneys, as well as in DNA synthesis and protein production.   

This amino acid can be found in foods such as red meat, poultry, fish, and dairy, making it particularly difficult for vegan or vegetarian individuals to intake a sufficient amount of l-arginine. 

NOW Foods is a family owned company since its start in 1968, and has relentlessly been making the natural supplement and products industry better since. Its mission has always been and is to provide value in their products which empower people to lead healthier lives all around.
