How Supplist works
Almost every supplement has 4.5 stars or more in its web shop. The difference is in what buyers write. Supplist reads those reviews and lists each product's recurring pros and cons, with the price per 100 g.
Supplist is owned by simpliSELF B.V. (BOD), which also sells its own supplements. Those aren't in this list and play no part in the order.
Where the reviews come from
From the public product reviews in the web shops of Body & Fit, Bodylab, Bulk, Lucovitaal, Myprotein, Optimum Nutrition, Upfront, Vitakruid, Vitaminstore, XXL Nutrition, Yummygums. For each product we read the newest reviews plus extra 1–3 star reviews, because that's where the complaints are. We can't verify ourselves that a review comes from a real buyer; some shops mark reviews as "verified buyer". What we do check: whether a shop hides critical reviews and whether a product has unusually few negative reviews. If so, it says so on the product.
We only show pros and cons about taste, mixing, packaging, price and complaints buyers report. What buyers say about effects we leave out: under the EU rules on health claims we may not repeat it as advertising. We show no reviewer names and no verbatim reviews. Product photos are shown straight from the shop's website; we don't copy them.
How the score is made
- AI verdict on the reviews (70%). An AI language model (Claude, by Anthropic) reads the reviews and gives a 0–10 verdict. Every pro and con has to point to the reviews it rests on; we count how many mention it.
- Shop rating, compared (20%). The shop's stars, stretched out against other products on the same review system, because each system inflates differently. With fewer than 8 products from a system, only the AI verdict counts.
- Consensus (10%). How much buyers agree with each other.
A product earns the Exceptional label with a score of 8 or more, high consensus and a shop that also shows negative reviews.
How the order is made
By default the list is sorted by Supplist score, highest first. When you tap what to watch for (sensitive stomach, caffeine, taste, plant-based, lactose), products with that drawback move down: a hard reason (like caffeine when you don't want it) weighs more than a complaint some buyers report. When you pick a goal, we show the type of supplement an EU-authorised claim belongs to, with that claim, ordered by score. You can also sort by price per unit or number of reviews. Brands and shops can't pay for a place, and whether we earn commission plays no part.
Prices
Every day we take prices from the shops' product pages, including VAT and excluding shipping, and work out the price per 100 g, per serving or per piece. A 'was' price is what the shop itself shows. Once we have 30 days of prices, we'll show whether a discount really is below the lowest price of the previous 30 days. The shop's price always applies.
AI on this site
The summaries, pros and cons and the English translation were made with AI and spot-checked by people. You can report a mistake via the contact details on About.
How we make money
We don't yet. Later, some buttons to a shop may become affiliate links: if you buy through one, the shop pays us a small commission and you pay the same. Such a link will carry an asterisk (*) and an explanation. It never changes the score or the order. We don't run ads.
What this isn't
This is a summary of what buyers say, not medical advice. The score is about the reviews, not about how well a substance works. If you take medication, are pregnant or have symptoms, talk to your GP or a dietitian.
Something wrong?
Brands and buyers can report a mistake or respond to a score. We look at every report and update the page if it's right. Reviews read on 16 October 2026, prices checked on 16 October 2026.
