How Can I Apply a Discount Code at Optimum Nutrition UK?

  1. Select Products: Head to optimumnutrition.com and start shopping by adding products to your basket. Add a product such as Gold Standard Whey Protein, pick your size and flavour, and click 'Add to Cart'.
  2. View Cart: Click the cart icon in the top right hand corner to view your items.
  3. Apply Promo Code: Under the order summary, there will be a 'Promo Code' box. Apply the coupon from DontPayFull and click 'Apply'. The discount should apply to your order.

Why is my Optimum Nutrition UK discount code not working?

  • Code valid only for selected products: Some discount codes work only on certain types of supplements or product categories. Read the terms to ensure your order is eligible. Bundles and clearance items are likely to be excluded.
  • Account-based deals: Some deals are only available to registered users or new customers. Make sure you are logged in and have met the requirements.
  • Multi-buy discounts may overlap: If you have an automatic multi-buy discount on, this may not apply. Check the savings and consider removing the auto-discount if the code you have is better value.
  • Regional restrictions: Certain codes apply only to UK customers and will not work if your billing or shipping address is outside of the UK. Check your location settings before using the code.
