About Optimum Nutrition
Optimum Nutrition (ON) is an American sports nutrition brand that manufactures and markets protein powders, performance supplements, recovery products, amino acids, vitamins, meal replacements, and fitness snacks. Established in 1986, it has grown into one of the most recognised names in the global sports nutrition industry and is particularly noted for its Gold Standard 100% Whey protein powder, which ranks among the best-selling whey protein products worldwide. Optimum Nutrition currently operates as part of the Glanbia performance nutrition portfolio.1
History
Optimum Nutrition was founded in 1986 by brothers Tony Costello and Mike Costello, who sought to improve the quality and consistency of sports nutrition products available to athletes. The company initially focused on premium protein supplements and quickly established a reputation for strict manufacturing standards and high-quality ingredients.2
Throughout the 1990s and early 2000s, the company introduced several key innovations to the market, including:
- Instantised protein powders designed for improved mixability
- Gold Standard 100% Whey
- Gold Standard 100% Casein, one of the first widely available all-casein protein powders
- Amino Energy, a formulation combining amino acids with caffeine to support energy and recovery3
In 2008, Optimum Nutrition was acquired by Glanbia PLC. This acquisition expanded the brand’s global manufacturing and distribution network while preserving the distinct ON brand identity.

Manufacturing and Quality
