Allergy Research Group(ARG)

A Tradition of Innovation

Allergy Research Group is one of the very first allergy oriented, hypoallergenic nutritional supplement companies and was founded in 1979 by Stephen Levine, Ph.D., a biochemist from UC Berkeley. For almost 30 years, Dr. Levine has dedicated himself to the latest research and the passionate pursuit of cutting-edge nutritional supplements.

Dr. Levine and Allergy Research Group were one of the first to introduce truly hypoallergenic products to the market, and developed the very first Buffered Vitamin C product. Dr. Levine's antioxidant research is legendary in that it created a unique, broad spectrum integration of the data with a very expanded perspective, which is still one of the most sophisticated antioxidant presentations even today. This work eventually lead to Dr. Levine’s groundbreaking textbook Antioxidant Adaptation, which he co-authored with Dr. Parris Kidd in 1985. For almost thirty years, Allergy Research Group has been known for the highest quality, most hypoallergenic, and most cutting-edge nutritional supplements available, and supplies products to physicians and healthcare practitioners around the world.

71370 ARG NAC N-Acetyl-L-Cysteine 120 Tabs

NAC (N-acetyl-L-cysteine) is an antioxidant that helps increase glutathione synthesis, and potentially has benefit during oxidative stress.* NAC is the acetyl derivative of L-cysteine. While L-cysteine plays important metabolic roles as a key antioxidant, a glutathione precursor, and a natural source of sulfur for metabolism, it is unstable and can become degraded during absorption. NAC on the other hand, is more stable than L-cysteine. Taken orally, NAC converts into L-cysteine after being absorbed, and raises blood and tissue cysteine levels. As a dietary supplement, NAC is a highly attractive alternative to L-cysteine. NAC can also be used instead of L-cysteine as an adjunct to Item #70130 Original AntiOx. Free form amino acid, high purity, well tolerated, and in tablet form to insure potency.
