Do vitamins and supplements work, and do you need them? The segment presents a health-focused Q&A with Dr. Mark Vaughan of Sutter Health and the Auburn Medical Group, centered on whether a healthy diet and regular exercise are sufficient for maintaining overall wellness. It raises key questions about the necessity of routine multivitamins for adults and children, what defines a balanced diet, and whether supplements are truly beneficial or potentially unnecessary. The discussion also highlights concerns about supplement use, including whether excess intake is simply eliminated by the body or could pose risks when taken without medical need.
