Optimum Nutrition was established in 1986 to satisfy consumer demand for consistent quality in sports nutrition. The company is also known for innovation, being first to produce a casein protein powder, and first to offer an all-micellar casein formula. ON's industry leadership can also be seen in the dominance of Gold Standard 100% Whey, universally recognized as the world's best-selling whey protein.
