Our verdict on each
HerbsPro
HerbsPro suits US buyers who already know which supplements they want and want them tested by someone else. Third-party tested products, a 30 day money back window and a catalogue covering multivitamins, vitamins minerals and omega 3 make it a broad shop rather than a narrow one.
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.

Pros and cons
HerbsPro
Pros
- Third-party tested products, so an outside lab checks what is in them rather than the brand checking its own.
- Per serving at $0.93 ranks 50 of 121, so the ongoing cost sits mid-field.
- The catalogue covers multivitamins, vitamins minerals and omega 3, wider than vitamins minerals at ProSolution Plus or vitamins minerals at TestRX.
Cons
- The entry price ranks 63 of 157 brands, so cheaper doors exist for a starter order.
- Shipping is listed for US only, which rules the brand out for anyone ordering from another country.
- The diet list in vegan and gluten free is short, so buyers on any other diet find nothing marked to suit them.
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
HerbsPro
Who it suits
- Buyers in US who want third-party tested products across multivitamins, vitamins minerals and omega 3.
- People on a vegan or gluten-free diet, the only diets in vegan and gluten free.
- Shoppers who like a choice of contact route, since support runs on email and phone.
Who should look elsewhere
- Buyers outside US. HerbsPro lists a single market, so check DocMorris or TestRX before ordering from another country.
- Anyone who wants one family only: TestRX lists vitamins minerals and ProSolution Plus lists vitamins minerals, both far shorter than multivitamins, vitamins minerals and omega 3.
- Shoppers whose diet is not among vegan and gluten free, who will find no matching label; DocMorris lists multivitamins, vitamins minerals and omega 3 for another look at the families on offer.
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
HerbsPro
What does HerbsPro cost to get started?+
The entry price for the HerbsPro multivitamin range is $27.79. That figure covers the product itself rather than a plan, and it is the number to set beside a single-product shop such as ProSolution Plus or TestRX, which list vitamins minerals and vitamins minerals. Reordering comes through on the same line.
How much is a serving on HerbsPro?+
A serving of the HerbsPro multivitamin range costs $0.93. Across this data HerbsPro ranks 50 of 121 brands on that measure, close to the middle of the field. Buyers who order every month get a truer picture from the per serving figure than from the entry price.
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.
