Optimum Nutrition was founded in 1986 in Illinois with one question: how can sports nutrition be made better? It describes itself as a brand for everyone from Olympians to everyday gym-goers, and has been part of Glanbia since 2008. The company's line is that there is more of you in you, and its products are meant to help you find it.
Protein is the core, led by Gold Standard 100% Whey, with a clear protein for those who prefer something lighter. Alongside it sit creatine, electrolytes and energy products, collagen, vitamins and minerals, a Platinum range and shakers. Bundles group popular products together.
The UK site is organised by goal as well as by product: lean physique, build muscle, weight management, active lifestyle, high performance and endurance. If you are new to supplements there is a beginner's guide, and a protein calculator helps you work out what suits your routine. Its Coach Optimum assistant is there for questions.
The brand says it controls every step from sourcing and formulation to testing and packaging, with in-house manufacturing and strict quality standards. It also publishes pages on authentic products and quality, which are worth reading if you are buying from a marketplace and want to know what the genuine article looks like.
The UK shop offers next-day delivery on qualifying orders placed before its weekday cut-off, with free delivery once your basket reaches the spend the brand sets. It does not deliver to the Channel Islands or the Isle of Man.
Joining the mailing list gets you a welcome offer on a first order, and bundles are priced to work out cheaper than buying the products separately. Any live code we have is listed on this page: copy it and enter it at checkout.
You can send back sealed, in-date products within the window in its returns policy. Opened products are not accepted back unless they are faulty, so it is worth starting with a smaller size of a new flavour.
We don't currently list a confirmed discount code. That doesn't mean the store has no promotions; check its website for current prices.
