Our verdict on each
Check My Body Health
Check My Body Health pairs a per serving cost of £0.07 with online GP, sexual health and menopause consultations priced at £0. It suits UK shoppers who want a broad supplement range, vegan, vegetarian or gluten-free formulas, and clinical help on the same account rather than a separate doctor subscription.
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.

Pros and cons
Check My Body Health
Pros
- Per serving cost of £0.07 ranks 5 of 121 brands, a much better showing than the entry price.
- Consultations priced at £0 cover online gp, sexual health and menopause with doctor and dietitian on the clinical side.
- The range spans multivitamins, vitamins minerals and omega 3, against the single vitamins minerals line at ProSolution Plus and the single vitamins minerals line at TestRX.
Cons
- The £12.99 entry price ranks 33 of 157 brands, so shoppers comparing the first order alone will find cheaper options.
- Clinical access is scheduled rather than on demand, so a same day question is harder to fit in.
- DocMorris lists electrolytes on top of multivitamins, vitamins minerals and omega 3, a line missing from multivitamins, vitamins minerals and omega 3 here.
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.
Who each suits
Check My Body Health
Who it suits
- UK buyers who want a single account for supplements and clinical advice, with online gp, sexual health and menopause sitting alongside multivitamins, vitamins minerals and omega 3
- Value shoppers who judge cost by the day rather than the first order, given £0.07 and its 5 place of 121
- Shoppers with vegan, vegetarian and gluten free needs, including vegan, vegetarian and gluten-free buyers
Who should look elsewhere
- ProSolution Plus, if vitamins minerals is enough and the wider range adds nothing to the basket
- DocMorris, if electrolytes matter alongside multivitamins, vitamins minerals and omega 3
- TestRX, if keeping the choice narrow to vitamins minerals suits the shopper better
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.

Questions about each
Check My Body Health
What does a first order cost?+
The Multivitamin Plus Iron plan starts at £12.99, and the same product works out at £0.07 per serving.

Are the online consultations free?+
Consultations are priced at £0, and the clinical service list covers online gp, sexual health and menopause. The clinicians behind them are doctor and dietitian, so a doctor or a dietitian is the person on the other side. For a shopper who wants a question answered before ordering, that part of the offer is free.
Nuun
What does Nuun cost?+
The entry point is $7.49 on the Nuun Sport range, and subscriptions take 15% off that price. There is no membership fee attached, and the amount you see at entry is the amount you pay for the box you order next.
What is the cost per serving?+
A serving of Nuun Sport works out at $0.75, which places the brand at position 42 of the 121 brands compared on that measure. If you take more than a tablet a day, the cost is worth multiplying out before you commit.
