Our verdict on each
MaximumSlim
MaximumSlim suits US buyers who want a broad supplement range at a low entry price and a per serving cost that repeats cheaply. The brand scores 9.1 overall, with a starting price of $19.99 and a 60 day money back window on the Original Green Coffee line.
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
MaximumSlim
Pros
- Entry price of $19.99 ranks 37 of 157 brands, so a single pack is an easy outlay.
- A subscription takes 20% off later orders, lowering the renewal side of the bill for regular buyers.
- The range covers multivitamins, vitamins minerals and greens, far broader than ProSolution Plus, whose catalogue is vitamins minerals.
Cons
- Per serving ranking of 85 of 121 is weaker than the entry price ranking, so daily use costs more than the pack price implies.
- Support runs on email and help centre, with no phone or chat line in the listed options, so quick answers depend on written replies.
- Product types stop at multivitamins, vitamins minerals and greens, while DocMorris lists multivitamins, vitamins minerals and omega 3, so sleep, stress and collagen buyers get nothing from this range.
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
MaximumSlim
Who it suits
- US buyers who want multivitamins, vitamins minerals and greens ordered from a single supplier
- Daily supplement users who judge cost by $1.67 a serving rather than the pack price
- Shoppers who want a 60 day money back window before committing to a greens coffee order
Who should look elsewhere
- Buyers after sleep, stress or collagen lines: DocMorris lists multivitamins, vitamins minerals and omega 3, none of which the MaximumSlim range covers.
- Shoppers who want a short, single category catalogue: ProSolution Plus stays on vitamins minerals and keeps the range narrow.
- People who only want vitamins and minerals listed: TestRX covers vitamins minerals and nothing wider, which is simpler to shop.
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
MaximumSlim
How much does MaximumSlim cost to start with?+
The Original Green Coffee pack is listed at $19.99, and each serving works out at $1.67. Buyers sampling a single product can judge the outlay from the pack price, while daily users should read the per serving figure, since that is the line that repeats.
What does subscribing change on the bill?+
A subscription takes 20% off later orders, so the entry price and the renewal price are separate figures. Shoppers who will reorder can plan around the lower number, and shoppers who expect to stop after a short run of orders should not count on the saving.
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.
