The brief
The brand in a paragraph.
Optimum Nutrition started in 1986 in New Jersey. The company built its reputation on protein powders and sports nutrition. Gold Standard Whey became their flagship product in the late 1990s. It dominated gym bags across America and beyond. The powder combined taste, mixability, and affordable pricing for serious lifters. Today Optimum Nutrition sells globally through major retailers and online channels. They own significant market share in whey protein and pre-workout formulas. The brand ranks first among 21,133 tracked brands in Supplements & Nutrition. Their products sit on shelves in most gyms and supplement stores. Price and availability made them the mass-market standard for protein.
