Scientists are investigating whether popular supplements could harm the aging brain

Recent research is prompting scientists to scrutinize the long-term effects of commonly used supplements like Vitamin D, omega-3 fish oil, and glucosamine, particularly in older adults. Initial findings suggest these supplements might not be as beneficial—or could even pose risks—to brain health in aging populations. This investigation is crucial because millions rely on these supplements for perceived cognitive and joint benefits, underscoring the need for more comprehensive data to guide health decisions. The implications could reshape supplement guidelines and influence public health strategies around brain health and aging.
