On January 12, 2009, the FDA ruled that products containing pyridoxamine are excluded from the definition of dietary supplements as defined by the Dietary Supplement Health and Education Act of 1994. The FDA stated that the status of Pyridorin as an investigational new drug, as a result of an application filed by BioStratum in July 1999 and effective on September 1, 1999, meant that "the marketing of pyridoxamine in a dietary supplement is essentially equivalent to the marketing of an investigational new drug as a dietary supplement" because there was an "absence of independent, verifiable evidence that the substance was marketed as a food or a dietary supplement prior to its authorization for investigation as a new drug."
