Our verdict
Science in Sport suits athletes and club competitors who want a tight, certified sports nutrition range rather than a full supplement aisle. Its whey protein powder lists 22 g of protein per serving, products are third-party tested, and the subscription takes 25% off.

Pros and cons
Pros
- Products are third-party tested and the range carries Informed Sport and GMP (informed sport and gmp), which separates it from ranges that rely on in-house checks alone.
- The subscription takes 25% off, which lowers the cost of every order after the first for anyone already training regularly.
- Ranks 32 of 66 brands on price from, placing the entry price of £29.99 in the cheaper part of the field.
- Broader than HUM Nutrition, which lists only plant protein and creatine (plant protein and creatine), since Science in Sport also covers electrolytes and protein bars (whey protein, creatine and electrolytes).
Cons
- Help runs on email, chat and help centre only, with no phone line listed, while a good share of protein powder brands carry phone support (54.2%).
- The range stops at whey protein, creatine, electrolytes and protein bars (whey protein, creatine and electrolytes), so there is no plant protein, pre-workout or mass gainer next to them, unlike Body Attack (whey protein, plant protein and creatine).
- The money-back window is 14 days, a shorter commitment than the returns window of 30 days typical across the brands listed.
- Protein per serving of 22 g sits under the protein powder median of 24, so scoop for scoop it is not the heaviest powder in the field.

Scored 9.3 / 10 by ThriveCue.
Who it suits
- Athletes in strength and endurance sports who want protein powder carrying Informed Sport and GMP (informed sport and gmp).
- People who will reorder regularly and can put repeat orders on the subscription for a discount of 25%.
- Shoppers in the United Kingdom, DE and IT who want a UK-based brand that runs its own shop and its own help centre.
Who should look elsewhere
- Body Attack, if you want plant protein, pre-workout, meal replacement or mass gainers on the same order (whey protein, plant protein and creatine).
- HUM Nutrition, if plant protein and creatine are the only categories on your shopping list (plant protein and creatine).
- Myvitamins, if you want a pre-workout alongside the protein (whey protein, creatine and electrolytes).
What it does well
Where Science in Sport earns its place is dosing and proof. The whey protein powder puts 22 g of protein into each serving, a plain number you can check against your own daily target instead of a marketing phrase. Products are third-party tested, so the batch is screened outside the company, which matters most to competitive athletes worried about what is in the scoop. The subscription applies a discount of 25%, and that is the part worth planning around: the first order is one price, and every reorder after it costs less. For a buyer who already knows how much protein they want each day, the case is simple. A measured amount, an outside check on the batch, and a cheaper second order.
Where it sits among rivals
On price from, Science in Sport ranks 32 of 66 brands, which puts the entry price in the cheaper part of the market without reaching the cheapest shelves. On protein per serving it ranks 26 of 43, a little above the middle. Read together, the two ranks describe a brand that is neither the cheapest way in nor the heaviest powder available. The rest of the argument sits with what a serving delivers and how the batch is checked, not with the sticker, which is where a subscription discount becomes the deciding number for anyone buying repeatedly.
Who runs it
Science in Sport trades as SiS (Science in Sport) Limited and is based in the United Kingdom. It was founded in 1992, and the same company still runs the shop, which settles the question of who sits behind the label on the tub. Support runs on email, chat and help centre, so questions about orders, delivery and product choice are handled in writing through email, chat and a help centre rather than by phone. That arrangement suits people who would rather keep the written record of an answer than chase a call, and it suits anyone comparing terms in writing before committing to a subscription.

Frequently asked questions
How much does Science in Sport cost to start with?+
The Rego whey protein powder is listed from £29.99, which is the entry point across the range rather than a bundle price. Whey protein, creatine, electrolytes and protein bars make up the listed categories (whey protein, creatine and electrolytes), so a first order is usually a single tub.
What happens to the price on a subscription?+
The subscription applies a discount of 25% once you are set up on it, which is the route that lowers what you pay each time you reorder. Buying without a subscription leaves the listed shelf price of £29.99 on the whey protein powder.
How much protein is in a serving?+
The whey protein powder lists 22 g of protein per serving, and on that measure the brand ranks 26 of 43, which puts it above the middle of the field rather than at the top of it.
Is the protein tested outside the company?+
Products are third-party tested, and the range carries Informed Sport and GMP (informed sport and gmp). GMP speaks to how the product is manufactured, while Informed Sport is the batch-testing scheme aimed at athletes who need certainty about contamination.
Which countries can I order to?+
The brand orders across GB, DE and IT, so the range is available in the UK, Germany, Italy, Spain and the US. The company is based in the United Kingdom and trades as SiS (Science in Sport) Limited, which is the entity behind the shop.
What is the returns window?+
The money-back window is 14 days, and support runs on email, chat and help centre. Across the brands in the comparison the typical returns window is 30 days, so check the window before ordering a large amount.
How do I get help with an order?+
Support runs on email, chat and help centre, so order queries, delivery questions and product advice are handled in writing. Anyone who would rather settle an order by speaking to someone should plan for the answer to arrive as an email or chat reply instead.
Does it sell anything beyond protein and creatine?+
The listed range covers whey protein, creatine, electrolytes and protein bars (whey protein, creatine and electrolytes). There is no plant protein, pre-workout, meal replacement or mass gainer in that list, so shoppers who need those should look at Body Attack (whey protein, plant protein and creatine).
