Why FDA quotes wording like this
Warning letters quote a company's own marketing as evidence of how a product is being sold. Under the Federal Food, Drug, and Cosmetic Act, a product promoted to cure, treat, mitigate or prevent disease is a drug, so disease claims on a supplement, CBD or wellness product can make it an unapproved drug. Some letters quote wording like "FDA approved" or "clinically proven" for other reasons. Each letter states its own charges, so read the source before deciding anything.
