Immunity Blend In 1994, Dr. Robert H. Keller founded the BIODORON Institute for Advanced Medicine, a leading-edge medical clinic that specializes in leading-edge treatment for immune system disorders and anti-aging. After reviewing lab results for years, Dr. Keller noticed a trend. He continued to see significantly low uric acid levels in subjects with immune disorders. He decided to explore this finding, and his initial research concluded that uric acid is the last antioxidant available to the body when all normal antioxidants have been depleted.
