Our verdict on each
Gruns
Gruns is a US supplement brand that suits adults who want a single daily routine covering greens and vitamins minerals at a serving cost of $1.07. Third-party testing and certification to nsf and gmp back it up, and the money back window gives time to judge it.
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
Gruns
Pros
- Covers greens and vitamins minerals in one brand, so a daily routine does not need splitting across makers.
- Third-party testing is stated, and the products carry nsf and gmp certification.
- Subscription orders are reduced by 55%, which is the cheapest way to hold the daily price at $1.07 a serving.
Cons
- Gruns sells in US only, so buyers elsewhere cannot order from the brand directly.
- The subscription discount of 55% is tied to repeat orders, and the entry price of $29.99 is the figure at the top of the range.
- Product types cover greens and vitamins minerals, and a wider range sits at DocMorris, which lists multivitamins, vitamins minerals and omega 3.
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
Gruns
Who it suits
- US adults who want greens and vitamins covered by a single daily subscription rather than separate products.
- Vegan shoppers and anyone avoiding gluten, as the range is vegan and gluten free.
- Readers who care about independent testing and named certification, since the products are third-party tested and carry nsf and gmp.
Who should look elsewhere
- Buyers outside the US, since Gruns operates in the United States only.
- Shoppers who want a single specific product such as omega-3, probiotics, collagen or electrolytes, which sit with DocMorris at multivitamins, vitamins minerals and omega 3.
- People who would rather test a men's health brand such as ProSolution Plus or TestRX, where vitamins minerals and vitamins minerals are the only listed types.
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
Gruns
How much does Gruns cost at the point of buying?+
The entry price is $29.99 across the collection. That is the figure a reader meets first when ordering. Once a routine is running, the cost that matters is the serving price of $1.07. Keep the two apart, since they are different numbers for different stages of buying.
What does a Gruns subscription cost over time?+
Repeat orders carry a discount of 55%, and that is the route that holds the serving price down. A one-off order pays the entry price of $29.99 instead, so the ongoing figure only applies on a schedule. A 30 day money back window gives a first order time to be judged.
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.
