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.
Vital Proteins
Pros
- Certifications are on the record: nsf and gmp covers its manufacturing standards.
- Support runs on email, phone and chat, so help is reachable by more than one route.
- Returns are straightforward with 30 days on the money-back window.
Cons
- The third-party tested answer is no, and the certifications on record, nsf and gmp, cover manufacturing standards instead.
- The range is narrow at collagen, greens and probiotics, where DocMorris carries multivitamins, vitamins minerals and omega 3 and Apotek Hjartat carries multivitamins, vitamins minerals and omega 3.
- The collagen range lists 1 flavour, which limits choice for anyone sensitive to taste.
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.
Vital Proteins
Who it suits
- US buyers who want collagen, greens and probiotics under one brand name
- People who prioritise certification and a clear returns window over the lowest per serving cost
- Shoppers who want a young company with a named parent behind it
Who should look elsewhere
- Buyers who want a wide vitamin and mineral range, where DocMorris and Apotek Hjartat both cover far more categories
- Anyone who needs independent batch testing on the label
- Shoppers outside the US looking for a local market

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.
Vital Proteins
How much does Vital Proteins cost to start?+
The entry price is $29.99, taken from the collagen peptides rather than from a bundle. Once you are ordering, the number that matters is $2.31 per serving. There is no membership needed to reach either figure.
Does a Vital Proteins subscription cost less?+
Yes, a subscription takes 15% off the ongoing cost. That discount applies for as long as you keep the subscription running, so the renewal price is lower than the one-off price but still recurring. Cancel and the one-off $2.31 per serving applies instead.
