Rising participation in fitness, bodybuilding and recreational sports is a core engine, as is the wider mainstreaming of high-protein diets for weight management and healthy aging. Aging populations in North America, Europe and parts of Asia are increasing demand for protein to support muscle maintenance, while clinical nutrition uses such as sarcopenia prevention and post-surgical recovery continue to expand. Emerging markets in Asia-Pacific and Latin America are also contributing through rising disposable incomes, urbanization and the spread of organized retail and e-commerce.
