Allergy Research Group® – A passion for purity, a legacy of trust

For more than 45 years, Allergy Research Group® has been a pioneer in hypoallergenic nutritional supplements, driven by an uncompromising commitment to purity, innovation, and clinical excellence. Founded in 1979 by Stephen Levine, Ph.D., a UC Berkeley biochemist, we were among the first to introduce truly hypoallergenic products to the market, setting new standards for quality and safety.

From groundbreaking innovations like Buffered Vitamin C to advanced antioxidant research that shaped the field, our history reflects a relentless pursuit of science-based solutions. Dr. Levine’s work, including the landmark textbook Antioxidant Adaptation (1985), continues to influence functional medicine today.

Why choose Allergy Research Group®?

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 and his team of experts have dedicated themselves 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.

Dr Levine and the science development team continue to work tirelessly to bring the latest ideas in nutritional medicine to clinicians and collaborate closely with many of the most eminent functional medicine physicians around the world in formulating and developing new nutritional supplements. This constant development of innovative new lines means that Allergy Research Group sets itself at the leading edge of nutritional supplement development.
