Optimum Nutrition

Optimum Nutrition (ON) is an American sports supplement brand founded by brothers Michael and Tony Costello in 1986. Since 2008, Optimum Nutrition has been part of the Irish **Glanbia plc** group, one of the world's largest manufacturers of dairy-based protein products. This ownership structure gives ON direct access to high-quality whey protein raw materials. ON is best known for its **Gold Standard 100% Whey** product, which is by far the world's best-selling whey protein. The product has been on the market for more than 25 years, has been improved several times, and is certified according to the **Informed-Choice** standard (independent control free of prohibited substances). The entire ON production chain complies with GMP standards, and each batch undergoes laboratory tests. In addition to proteins, the range also includes creatine, amino acids (BCAA, glutamine), pre-workout boosters (Gold Standard Pre-Workout) and recovery products. Omegafit chose Optimum Nutrition for two reasons: 1) Gold Standard 100% Whey is the benchmark in the category — the product by which other whey proteins are judged; 2) Informed-Choice certification and Glanbia’s manufacturing capacity ensure consistent quality that doesn’t fluctuate from batch to batch. Flagship products are **ON Gold Standard 100% Whey** (a blend of whey isolate and concentrate) and **ON Gold Standard Pre-Workout** (a pre-workout booster). Target audience: gym goers, athletes, and fitness enthusiasts who value proven recipes.
