Swanson Premium's Raw Spleen Glandular supplement comes from a full line of products developed by Swanson Health Products because of a strong demand from you. Back in the 1930s, four key factors led to glandulars becoming popular throughout the supplement world: the material was abundant to produce these products, the historical rationale for use and the evidence of safety were strong and their affordability made them particularly attractive. All of our glandular products are frozen when raw to preserve active components then desiccated (dried), powdered, defatted and tested at GMP laboratories in the heartland of America.
