Glanbia Plc

A global nutrition company based in Kilkenny, Ireland, Glanbia makes the protein powders, sports supplements, and nutritional ingredients behind brands like Optimum Nutrition's Gold Standard whey, BSN, and Isopure. It was born in 1997 when two Irish dairy cooperatives, Avonmore Foods and Waterford Foods, merged — and its name comes from the Irish words glan ("pure") and bia ("food"), meaning "pure food." The company grew out of Ireland's dairy-farming tradition and now sells its nutrition products around the world.
