In this third and final installment of our DSHEA at 30 series, we continue our discussion of the Dietary Supplement Health & Education Act of 1994 (DSHEA) with industry trade associations, whose memberships include retailers, manufacturers, brands, raw materials suppliers, and industry advisers and consultants. In Part I and Part II, we asked independent natural products retailers, industry manufacturers, ingredient suppliers, and other leaders to tell us how they are advocating to preserve access to healthful natural products. This includes inights from Loren Israelsen, Founder and President, United Natural Products Alliance (UNPA). Here, in Part III, industry associations and advocates relate best practices.
