Physicians and healthcare practitioners around the world depend on Allergy Research Group for their patients' nutritional support. Our doctor formulated supplements are created using evidence-based research, with a focus on hypoallergenic ingredients. We use only the purest raw materials available and follow strict quality control procedures in every stage of production, including inspection of raw materials, manufacturing, packaging, and storing. Since our inception in 1979, ARG has sought out pure, hypoallergenic solutions to aid even the most chemically sensitive. This means we were hypoallergenic before it was cool. Our dedication to clean supplements continues, with higher purity standards than the majority of the industry. Because of this, many sensitive patients who typically react to supplements tolerate ARG products.
