Because of a strong demand from you, Swanson Health Products has developed a full line of glandular products, including our Lung Glandular supplement. 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. These truths remain today. All of our glandular products are frozen to preserve active components then desiccated (dried), powdered, defatted and tested at GMP laboratories in the heartland of America.
