About Optimum Nutrition
The range in brief
Whey protein is the backbone, led by Gold Standard 100% Whey. Lighter options include Protein Water and Clear Protein, and there are ready-made shakes and bars for eating on the move. Strength-focused shoppers can pick up Micronised Creatine Powder or Platinum Creatine Plus. The Platinum line, energy products, mass gainers, collagen peptides and vitamins fill out the shelves, and a vegan and plant-based section completes it.
