Our editorial rule
We distinguish general wellness information from diagnosis or treatment. For supplement claims, we distinguish research on ingredients from evidence on a finished product.
Health noteThis article is general information, not medical advice. If you have a respiratory condition, take medication, are pregnant or breastfeeding, or are considering changing treatment, seek appropriate professional guidance.
Editorial sources & standards
Our regulatory baseline includes FDA guidance on dietary-supplement claims and FTC health-products advertising guidance. We update commercial details from current seller materials rather than assuming old prices or labels remain accurate.
