Optimum Nutrition

Optimum Nutrition Inc., was founded in 1986 by brothers Tony and Michael Costello, and is owned by the Glanbia group. The company produces an overwhelming variety of sports nutrition products, from vitamins and minerals, to shakes, to protein powders, to bars, to energy-promoting formulas. In fact, Optimum Nutrition supplements have a reputation for being the most diverse on the global market.


Renowned for its innovative approach, the company is constantly expanding and developing its products, according to the latest scientific research and the newest technological breakthroughs. It's also known for using only high-quality, pure ingredients, which arrive certified and are then tested in the Optimum Nutrition products labs.


It was the first brand to sell casein protein powder and also the first to sell all-micellar casein formula. Optimum Nutrition supplements are sold in more than 10,000 retailers in the United States and in more than seventy different countries around the world.


New Products


New, cutting-edge Optimum Nutrition products are released on a frequent basis. One popular recent addition is Platinum Pre-, which supports energy and focus at the pre-workout level. Two scoops contain 4g of micronized citrulline and perform citrulline peptides, 3.2g of carnosyn beta-alanine, 250mg of capsicum fruit extract, 500mg of phytoblend, 200mg of Vitamin C and 400mg of caffeine. 


Other Platinum Optimum Nutrition supplements include Hydrobuilder and HydroWhey. Both offer high-powered blends designed to promote both efficient protein intake and nutrition. Hydrobuilder includes essential amino acids (13.5g per serve), micronised CreaPure (5g), BetaPower (2.5g), an enzyme complex, micronised BCAAs, glutamine, arginine and citrulline. HydroWhey offers 30g of pure protein per serve, as well as enzymes to assist absorption.


Optimum Nutrition Protein


Optimum Nutrition's 100% Whey Gold Standard is made up of the purest form of protein in existence - Whey Protein Isolates (WPIs). Every serving contains 24g of protein, including BCAAs, glutamine and glutaminic acid. Moreover, 100% Whey Gold Standard is available in an extensive range of flavours, including caramel toffee fudge, rocky road and banana creme, and in two convenient sizes, to meet varying demands (2.27kg and 4.5kg).


Optimum Nutrition 100% Gold Standard Natural Casein is another option for protein. Comprised of micellar protein, it provides 24g of sustained-release protein in every serving, which is helpful in both pre-workout and post-workout contexts. It also contains branched-chain amino acids (commonly known as BCAAs) and glutamine peptides, which promote muscle mass through the creation of an anabolic environment.
