Bundle and Save - Multi-Buy Packs from £15
Science in Sport offers pre-built multi-buy packs that bring the per-unit cost down compared to buying individually. A 6-pack of GO Energy gels, for example, works out cheaper per gel than singles, and larger 30-serving tubs of hydration powder offer better value than the smaller sachets.
NHS and Blue Light Card Holders Save 15%
Registered healthcare workers and emergency service staff can claim 15% off through the Blue Light Card scheme. Verify your status via the Blue Light Card portal, then apply the provided code at checkout. Valid on most full-price nutrition and supplement lines.
15% Off Your First Order with Newsletter Sign-Up
Pop your email into the Science in Sport newsletter form and you'll receive a one-time 15% discount code within a few minutes. The code works on full-price items across the store, making it the best introductory saving if you're new to the brand and want to try a range of products.
Refer a Friend - You Both Get £10 Off
Share your personal referral link with a training partner or gym buddy. When they place their first order, they receive £10 off and you earn £10 in reward credit to spend on your next purchase. The credit lands in your loyalty account once their order ships.
Free Shaker Bottle with Bundles Over £40
When your basket passes £40 on selected bundle deals, Science in Sport throws in a free shaker bottle so you can mix your recovery shakes straight away. The gift is added automatically when qualifying items are in your cart - no code needed.
Free Standard Delivery on Orders Over £25
Spend £25 or more and standard UK shipping is included at no extra cost. Since a couple of boxes of GO gels or a single tub of whey isolate typically clears that threshold, most nutrition top-ups will qualify automatically without needing to add filler items.

The clearance and sale section at Science in Sport regularly features end-of-line and seasonal products at reduced prices. You'll find everything from older packaging of energy bars to discontinued flavours of REGO recovery powder, often with discounts reaching 30% off the original retail price.
