“Allergy Research Group products are intended for healthcare practitioners, whereas NutriCology products are for consumers. Some formulas are offered only in the ARG label. Formulas that are offered in both labels differ only in their labels, not in ingredient content or quality.”
For more than thirty years, Allergy Research Group® has been known for the highest quality, most hypoallergenic, and most cutting-edge nutritional supplements available.
Physicians and healthcare practitioners around the world depend on ARG for their patients’ nutritional support.
Originating with the ground-breaking oxidant/antioxidant work of Stephen Levine, Ph.D., Allergy Research Group was one of the first to introduce truly hypoallergenic products to the market.
