More than half of adults in high-income countries take dietary supplements, feeding a global market well above 150 billion US dollars a year — yet under frameworks like the US DSHEA (1994), supplements reach the market without pre-approval of safety or efficacy, and quality, dosing accuracy and interactions with medicines remain the consumer blind spots documented by the NIH Office of Dietary Supplements and EFSA. GMJ News covers this field with original, evidence-graded journalism generated from our own structured databases: browse the Ingredients A-Z evidence profiles and the full SupplementIndex — dosage, safety, interactions and label literacy, referenced to NIH ODS, EFSA and Cochrane.
