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.
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.
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.
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.

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.
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.
