Frequently Asked Questions

How can I get a discount on my first Optimum Nutrition UK order?

New customers can receive 15% off their first order by signing up for the Optimum Nutrition UK newsletter and confirming their email address. The discount code is sent by email and is valid for a limited period. It cannot be combined with other promotions or bundles.

Does Optimum Nutrition offer discounts on Gold Standard Whey Protein?

Yes. Optimum Nutrition periodically offers savings on selected Gold Standard 100% Whey Protein products, including multi-pack bundles. Discounts and prices can vary by flavour and pack size, so check the current product listing before ordering.

Can I save money by subscribing to Optimum Nutrition supplements?

Yes. The Subscribe & Save programme offers 15% off the first subscription order and 20% off recurring eligible orders. You can choose a delivery schedule and change, pause or cancel your subscription. Free delivery is available on subscription orders over £25, subject to the programme's terms.

Does Optimum Nutrition UK offer free delivery when using a discount code?

Yes. Standard UK orders over £50 qualify for free delivery. Orders below this threshold incur a £3.99 delivery charge. Discount codes may reduce the qualifying order value, so check the final basket total and delivery charge before payment.

Can I use an Optimum Nutrition coupon code on bundles or multi-buy deals?

Generally, no. Optimum Nutrition's promotional terms state that discount codes cannot be combined with bundles or combination deals. If a Gold Standard Whey bundle already has a reduced price, check its specific terms before trying to apply another coupon.

Can I get discounts on Optimum Nutrition creatine, pre-workout and electrolyte products?

Yes. The UK store runs product-specific promotions across selected supplements, which can include Micronised Creatine, Gold Standard Pre-Workout and electrolyte products. Eligibility and savings vary, so check the official product pages for current prices and offer conditions.

Why is my Optimum Nutrition UK discount code not working?

A code may have expired, already been used, or be restricted to eligible products or first-time orders. Newsletter discounts cannot be reused or combined with bundles and other promotions. Check the code's validity, your basket contents and the official promotion terms before completing checkout.
