Pros and cons
Britt's Superfoods
Pros
- Third party testing is confirmed, with organic certification and vegan, vegetarian and gluten free labels on the range.
- Subscription orders are discounted by 15%, and the money back window runs 30 days.
- A tight greens and probiotics shelf, narrower than Life Extension's multivitamins, vitamins minerals and omega 3.
Cons
- Entry price is the soft spot: the wheatgrass juice plan costs £60 and ranks 140 of 157 brands on price from.
- The range is limited to greens and probiotics, so collagen, sleep and stress shoppers are better served by Life Extension's multivitamins, vitamins minerals and omega 3.
- Diet labels cover vegan, vegetarian and gluten free only, and organic is the sole certification on organic.
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.
Who each suits
Britt's Superfoods
Who it suits
- Readers who want a short greens and probiotics list rather than a broad vitamin shelf.
- Subscribers who prefer a 15% discount and a 30 day money back window.
- Shoppers in the markets covered by GB, GG and JE.
Who should look elsewhere
- Anyone after a full vitamin shelf, since the range here is greens and probiotics only while DocMorris lists multivitamins, vitamins minerals and omega 3.
- Sleep and stress shoppers, since Life Extension covers multivitamins, vitamins minerals and omega 3 and this brand does not.
- Shoppers who want a broad shop style catalogue, since Apotek Hjartat lists multivitamins, vitamins minerals and omega 3.
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.

Questions about each
Britt's Superfoods
What does Britt's Superfoods cost to start?+
The wheatgrass juice plan is priced at £60 for the pack, which works out at £2 a serving. Budget the full £60 on a first order, then use £2 a serving to judge what a daily drink costs over time.
Does a subscription bring the price down?+
Yes. Subscription orders are discounted by 15% on each repeat delivery, so the renewal figure sits below the £60 entry price on the wheatgrass juice plan. The one off pack price of £2 a serving does not move.
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.
