Raw Adrenal Glandular from Swanson Health Products introduces the concept that like supports like--consuming raw adrenal tissue supports our own adrenal glands. Swanson brand glandular supplements are made only from raw, cold-processed bovine glandular tissue collected at USDA-inspected facilities. This high-quality tissue is desiccated (dried), defatted (when applicable) and powdered at cGMP certified laboratories in Nebraska.
