Our verdict on each
BiltRx
BiltRx suits readers who want a US online clinic and a supplement range on one account, with vitamins minerals, collagen and greens in the catalogue and a plan at $65 a month. Entry pricing starts at $36.90 for supplements, and a money back window of 30 days softens a first order.
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
BiltRx
Pros
- A supplement range and a clinic in one place: online gp, prescriptions and weight loss sit alongside vitamins minerals, collagen and greens on the same account.
- Support covers email, phone and chat, so a phone line and live chat sit next to email and a help centre.
- A money back window of 30 days covers the trial period on supplement orders.
Cons
- BiltRx does not accept insurance, so the $65 monthly plan is paid directly rather than through a policy.
- Consultations run through doctor alone, with no pharmacist or nurse practitioner in that list.
- The shop serves US only, and gluten free is the sole diet listed, so the range is narrow on both geography and diet.
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
BiltRx
Who it suits
- US readers who want a supplement order and a clinic consultation to sit on one account rather than two.
- Readers who start with the men's vitality bundle at $36.90 and stay on the subscription rate.
- People who prefer a phone line or live chat, since support covers email, phone and chat.
Who should look elsewhere
- Buyers who want a longer catalogue: DocMorris lists multivitamins, vitamins minerals and omega 3, a wider set of types than the vitamins minerals, collagen and greens here.
- Readers who want greens, collagen and sleep and stress formulas from TestRx or ProSolution Plus, since TestRx lists vitamins minerals and ProSolution Plus lists vitamins minerals.
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
BiltRx
What does a BiltRx supplement order cost?+
Supplements start at $36.90, and subscribers pay 10% off the standard rate, so repeat orders cost less than the first ticket price. The clinic plan is billed apart from the shop at $65 a month, and any prescribed medicine sits outside that figure too.
What does the BiltRx monthly plan cover?+
The plan is $65 a month, and the service list covers online general practitioner consultations, prescriptions, weight loss, hair loss, sexual health, skin and menopause care. The supplement range is bought separately in the shop, so a plan does not include a daily vitamin order.
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.
