Millions of glucosamine users face potential health risks and may discontinue use, reducing out-of-pocket spending on supplements. Consumers may shift to alternative joint pain treatments or prescription medications, increasing healthcare costs. Elderly populations and Alzheimer's patients' families face difficult treatment decisions and potential liability concerns.
FDA may initiate safety reviews and labeling requirements for glucosamine products. Potential congressional hearings on supplement regulation oversight. Possible class-action litigation and settlement costs. Enhanced post-market surveillance of supplements. Stricter clinical trial requirements for supplement approval. Potential mandatory warning labels or market restrictions.
