Brain-Care Pills Under Scrutiny: Omega-3, Glucosamine, and Vitamin D in Question
A Washington Post–style review finds that widely used supplements—fish oil/omega-3, glucosamine, and vitamin D—may not protect against aging brains and could be linked to adverse cognitive outcomes in some studies. Most evidence is observational and not causal, and the FDA does not pre-approve supplements for safety. The bottom line: don’t bank on these pills for brain health; prioritize lifestyle factors (regular movement, sleep, real food) and consider getting omega-3s from food, while discussing any supplement use with a healthcare provider.
