Optimum Nutrition
**Optimum Nutrition — Sports Nutrition Excellence Since 1986** Optimum Nutrition (ON) is a globally recognised sports nutrition brand founded in Illinois, USA, in 1986 by brothers Tony and Mike Costello. With decades of experience, a broad product portfolio and a strong focus on quality management, the brand has become a familiar choice among athletes and fitness enthusiasts worldwide. One of its best-known products is **Gold Standard 100% Whey**. The product range also includes creatine, mass gainers, casein protein, amino acids, pre-workout formulas, protein bars and other sports nutrition products. **Quality and Manufacturing** Optimum Nutrition emphasises raw material selection, ingredient verification, manufacturing controls and finished-product quality. Its official materials describe ingredient documentation requirements, laboratory testing and ongoing quality assurance at manufacturing facilities. Depending on the product and destination market, manufacturing may take place in the United States, the United Kingdom or India. The country of manufacture should therefore be confirmed on the individual product's packaging rather than assumed from the brand's country of origin. **Quality Standards and Product Verification** The company references GMP and other applicable manufacturing and food safety systems. Selected products may be registered with independent testing programmes such as Informed Sport or Informed Choice. These registrations do not automatically apply to every product in the range. Optimum Nutrition offers products for a variety of sports nutrition goals, including supplementing daily protein intake, supporting strength-training nutrition and helping users meet their planned nutritional requirements. Customers should review ingredients, serving sizes, allergens and manufacturer instructions before use. Explore the available Optimum Nutrition range at NutriZone, compare product details and select an option that fits your goals and budget. To help verify authenticity, check the packaging, batch number, expiry date and any official TRU Seal verification code provided with the product.
