Our verdict on each
Nuun
Nuun suits readers who want electrolyte tablets bought as they need them, with an entry price of $7.49 on Nuun Sport and $0.75 a serving. Vitamins-and-multivitamins rivals that bundle a monthly plan charge on delivery rather than letting you stop, so Nuun fits anyone who buys by the box.
Protein Works
Protein Works suits shoppers who want a wide range of daily supplement categories at a low entry price, with £8.99 to start. Buyers who put independent lab testing at the top of their list should look further, since third-party testing is not offered.

Pros and cons
Nuun
Pros
- Entry price of $7.49 on Nuun Sport puts the brand at position 11 of the 157 brands tracked on price from.
- A serving of Nuun Sport costs $0.75, which lands at position 42 of the 121 brands compared on cost per serving.
- Every product is third-party tested, against 84.5% of brands in the vitamins-and-multivitamins category that report the same.
Cons
- Where it runs is narrow: the range is built for US and CA, so readers in the UK are better served by DocMorris, which covers multivitamins, vitamins minerals and omega 3.
- Protein per serving sits at 0 g, well under the 24 median across the brands compared, so anyone buying this alongside a pre-workout still needs a separate protein source.
- The range is built on electrolytes, multivitamins and vitamins minerals rather than on vitamins alone, and TestRX stays closer to vitamins minerals for readers shopping purely for a daily vitamin.
Protein Works
Pros
- Covers a wide list of categories in multivitamins, vitamins minerals and omega 3, from multivitamins to electrolytes.
- Entry point of £8.99 with a per serving cost of £0.15, ranked 15 of 121 brands on price per serving.
- The range suits different diets, with vegan, vegetarian and gluten free options on the multivitamin formula.
Cons
- Delivery covers GB, IE and FR, which is a narrower set of markets than some pharmacy-led rivals.
- The range carries 8 flavours on its whey protein line, but the entry pricing and per serving cost come from the multivitamin product.
- The £8.99 entry price ranks 23 of 157 brands, so the price on the front of the pack sits mid-table.
Who each suits
Nuun
Who it suits
- Readers after electrolyte tablets rather than capsules, since the range covers electrolytes, multivitamins and vitamins minerals.
- Anyone in the markets Nuun serves, listed as US and CA.
- Shoppers on restricted diets, given the range is labelled for vegan, gluten free and kosher.
Who should look elsewhere
- Readers in the UK, who should look at DocMorris and its own range of multivitamins, vitamins minerals and omega 3.
- Anyone shopping only for a daily vitamin, since ProSolution Plus sells vitamins minerals and TestRX vitamins minerals alone.
Protein Works
Who it suits
- Shoppers who want vitamins, probiotics, greens, collagen, sleep and stress, nootropics and electrolytes from one brand.
- People on vegan, vegetarian and gluten-free diets, covered by vegan, vegetarian and gluten free.
- Buyers in the United Kingdom, IE and FR who value a low per serving cost of £0.15.
Who should look elsewhere
- Buyers who need third-party tested products, since DocMorris and other pharmacy brands list independent testing in this category.
- Anyone outside GB, IE and FR, where the GB, IE and FR delivery list does not reach.
- People who want licensed or prescription oversight, as no licence appears against this brand.
