Our verdict on each
Dr. Wilson's
Dr. Wilson's suits buyers who want a small, focused supplement range with a long refund window, and who can live without independent batch testing. Formulas carry gmp manufacturing standards, and the 90 day money back promise takes the cost risk out of 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
Dr. Wilson's
Pros
- The catalogue is deliberately short: vitamins minerals, probiotics and sleep stress, so a shopper can find a formula without sorting through unrelated categories.
- The 90 day money back window is generous next to the 30 day returns median across the brands on the site.
- Manufacturing follows gmp, a standard shared with 53.2% of the brands on the site.
Cons
- Third party testing is no, and independent lab verification is not among its certifications (gmp), so the 90 day money back promise carries the risk on cost instead.
- The list stops at vitamins minerals, probiotics and sleep stress, while DocMorris carries multivitamins, vitamins minerals and omega 3, so shoppers wanting a category beyond vitamins, probiotics and sleep and stress need a different brand.
- Per serving cost sits at €1.17 against €1.01 in the vitamins field, so daily cost runs above that category.
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
Dr. Wilson's
Who it suits
- Shoppers who want a short list of vitamins minerals, probiotics and sleep stress rather than the wider catalogue at DocMorris.
- Buyers who treat a 90 day money back promise as a workable stand in for batch level testing.
- People in the United States, CA and GB who would rather ask a question by phone than search a help centre.
Who should look elsewhere
- Buyers wanting a category beyond vitamins, probiotics and sleep and stress should look at DocMorris, which lists multivitamins, vitamins minerals and omega 3.
- Shoppers who will only buy independently tested formulas should choose a brand that publishes results, since third party testing is no here.
- Price shoppers buying only vitamins and minerals gain little from the shorter list, since vitamins minerals and vitamins minerals match it.
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
Dr. Wilson's
How long is the money back promise on Dr. Wilson's supplements?+
Every purchase carries a 90 day money back promise, which is the main risk reversal here. It is a longer window than the 30 day returns median across the brands on the site, so there is room to run a formula through a full routine before deciding to keep it.
Are Dr. Wilson's supplements third party tested?+
Third party testing is no. Nothing in the range is verified by an independent lab, which puts the brand on the minority side of the market: 85.6% of the brands tracked publish independent testing. The 90 day money back promise covers the cost side of the risk, not laboratory proof of the contents.
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.
