This amino acid was first isolated from Lupin seedlings in 1886 by a German chemist by the name of Ernst. Schulze. Later, in 1998 three American scientists were awarded the Nobel Prize for their discovery of the important part L-Arginine plays in the production of nitric oxide. Nitric oxide is a powerful vasodilator, which means it helps the arteries to relax and blood to flow more freely. For over three decades, medical professionals and researchers have continued to study the effects of L-Arginine on cardiovascular health and possible benefits. Most recently, discoveries have noted the ability of L-Arginine to aid the body in releasing hormones involved in retention and building of lean muscle mass, encouraging a healthy circulatory response and to speed the recovery of wounds.

L-Arginine is a semi-essential amino acid, meaning our bodies can produce it under certain circumstances, however, it is readily available in dietary and supplemental forms. Red meat, eggs, fish and dairy all contain small amounts of this amino acid, sadly, our bodies and diets don't often contain sufficient amounts. Superior Labs produces one of the leading L-Arginine supplements on the market to date. Our quality control measures exceed those recommended by industry professionals. We take our job very seriously and want you to be completely satisfied with your supplement. Let's talk a little more about the benefits of Superior Labs' L-Arginine.

To produce a high quality L-Arginine supplement, it takes a highly oxygenated environment and an innovative fermentation process. Because L-Arginine is biosynthesized from the acid L-Glutamine, we utilize strains of bacteria that have a high capability of producing L-Glutamine, which in turn produces the L-Arginine. After fermentation is complete, bacterial cells and proteins are removed and purified, removing any toxins or impurities. Finally, the purified bacterial cells and proteins are concentrated and L-Arginine crystals removed and processed. 

WHAT YOU WON'T FIND IN OUR PRODUCTS is harmful magnesium stearate, dioxides, preservatives or other potentially harmful artificial ingredients of any kind. This means, you can rest easily knowing you are receiving the safest, most efficient and chemical-free product possible. We are committed to the health of our customers, community and planet.
