adequately substantiated definition
adequately substantiated means and who must provide the evidence—the government, the manufacturer, or an independent body.39 The Environmental Working Group (EWG), a harsh critic of the cosmetics industry and federal regulators, has challenged the FDA in a petition to give practical meaning to the term “adequately substantiated.” In a written response the FDA said it would not undertake rulemaking to define “adequately substantiated” but would look into the possibility of issuing guidance in the future.
