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. Founded in 1986, the brand has become one of the world’s best-known names in sports nutrition and is particularly recognized for its Gold Standard 100% Whey protein powder, one of the best-selling whey protein products globally. Today, Optimum Nutrition is part of the Glanbia performance nutrition portfolio. [1]
History
Optimum Nutrition was founded in 1986 by brothers Tony Costello and Mike Costello, who wanted to improve the quality and consistency of sports nutrition products available to athletes. The company started with a focus on premium protein supplements and quickly built a reputation for strict manufacturing standards and ingredient quality. [2]
During the 1990s and early 2000s, the company introduced several innovations, including:
-
Instantized protein powders for improved mixability
-
Gold Standard 100% Whey
-
Gold Standard 100% Casein, one of the first widely available all-casein protein powders
-
Amino Energy, which combined amino acids with caffeine for energy and recovery support [3]
In 2008, Optimum Nutrition was acquired by Glanbia PLC, expanding its global manufacturing and distribution network while maintaining the ON brand identity. [4]

Manufacturing and Quality
One of Optimum Nutrition’s defining characteristics is its emphasis on manufacturing quality. Unlike many supplement brands that outsource production, ON operates company-controlled manufacturing facilities in multiple countries, including the United States and the United Kingdom. The company states that every ingredient is tested before production and finished products undergo additional quality testing before release. Facilities follow current Good Manufacturing Practices (cGMP), and some are certified through programs such as Informed Sport and Informed Choice. [5]
The company reports rejecting large quantities of raw materials each year if they do not meet internal quality standards. [6]
