Arginine shows promise as low-cost weapon against Alzheimer’s in animal studies Researchers at Kindai University in Japan found that oral arginine, a common amino acid, reduced toxic amyloid protein buildup in fruit flies and mice genetically modified to model Alzheimer’s disease. Laboratory tests showed arginine prevented the formation of amyloid beta aggregates, with stronger effects at higher concentrations. Treated mice showed fewer brain plaques, lower brain inflammation and improved performance on memory and behavior tests. Arginine is already clinically safe, inexpensive and able to reach the brain, making it a candidate for drug repurposing. Researchers caution that human clinical trials…
