Our verdict on each
KoRo
KoRo suits adults inside Germany who want a broad supplement range at a low cost per serving rather than a plan or a subscription. The money back window of 14 days and the DE reach keep the commitment small, though products are not third-party tested and the listed certification is organic.
Science in Sport
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
KoRo
Pros
- A serving cost of €0.01 makes daily use inexpensive, and the entry price of €19.50 keeps a first order small.
- Range spans vitamins minerals, omega 3 and probiotics, wider than the vitamins and minerals focus at ProSolution Plus and TestRX.
- Products suit vegan and vegetarian diets, and the listed certification is organic.
Cons
- Third-party tested is no, and the listed certification is organic, so an independent potency check sits outside what is stated.
- Price from ranks 44 of 157 brands, so the entry price is not the cheapest in the comparison.
- The range covers DE only, which is narrower than a multi-line pharmacy such as DocMorris.
Science in Sport
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.
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.
Who each suits
KoRo
Who it suits
- Adults in DE who order one-off supplements rather than a plan
- Vegan and vegetarian shoppers, since the diets listed are vegan and vegetarian
- People who weigh cost per serving above all, given the rank of 1
Who should look elsewhere
- Shoppers who require third-party tested products, since third-party tested is no
- Anyone outside DE, where the range does not reach
- Buyers chasing sleep, stress and nootropic lines, listed for DocMorris in multivitamins, vitamins minerals and omega 3 but not part of vitamins minerals, omega 3 and probiotics
Science in Sport
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).

Questions about each
KoRo
How much does KoRo cost?+
Prices start at €19.50, and the cost per serving is €0.01. The first figure matters for a single purchase, the second for anyone taking a product every day. The price shown is the one you pay, so no second bill arrives later.
Is KoRo cheaper than rival supplement brands?+
It depends which measure you use. On price from, KoRo ranks 44 of 157 brands, so the entry price sits mid-table. On price per serving it ranks 1 of 121 brands, the stronger result of the two for a daily user.
Science in Sport
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.
