Health supplement use in the US spans key ingredients—omega-3 fatty acids, calcium, magnesium, zinc, probiotics, vitamin C, and vitamin D—measured in 2017–2018 NHANES. Alongside usage patterns, the industry is shaped by required “Supplement Facts” labeling under 21 CFR 101.36 and quality systems used in manufacturing. We also cover evidence on outcomes, plus supply-chain and logistics pressures and regulatory oversight that affect what reaches consumers.
