Researchers at Kindai University have discovered that oral arginine, a naturally occurring amino acid, can significantly suppress amyloid-β (Aβ) aggregation in animal models of Alzheimer’s disease. The study found that arginine prevented Aβ42 from clumping and reduced plaques and inflammation in mouse and fruit fly models carrying Alzheimer’s-related mutations. Treated mice showed improved cognitive performance alongside reduced neuroinflammation, indicating broad neuroprotective effects. As arginine is clinically safe, affordable, and widely available, it holds strong potential as a repurposed therapeutic strategy pending further human studies.
