Neither of these is trying to sell you anything, and both are more useful than the product pages around them if you are still deciding whether this whole category is worth your money. One walks the shelf and says what each ingredient’s research actually found. The other hands you a set of questions to ask any label, then answers them about this one and records where it comes up short.
For the reader who is going to leave without ordering, which is most of them.
The two guides
One about the research, one about the label in front of you.
Ingredient by ingredient, what the research found
Six botanicals dominate this shelf and their evidence bases are nowhere near equal. Two of them reach umbrella-review level; four do not come close. The guide takes each one in turn, prints the amount its trials used, and then deals with the older vein-and-capillary family that shares the same shelf space and supplies every name on this particular bottle.
A scorecard you can carry into any shop
Does a panel exist? Is a quantity printed? Could the ingredient list plausibly produce the claim on the front of the box? Seven questions in the order that disqualifies fastest, answerable from a label in about five minutes. Then the same seven run against this product, which scores three, with the four failures written out at more length than the passes.
Why a commercial website publishes these
A scorecard nobody fails is a brochure with a table in it.
Because the most useful thing a retail desk can give a reader is the ability to judge its own product, and a page that only works if you buy something is easy to spot.
The second guide scores this bottle and records two rows it fails outright. That is not modesty: a scorecard that awards full marks to the product beside it is worth nothing to the reader and everybody knows it. The rows it passes are worth more once the rows it fails are on the same page.
Neither guide is a sales page and neither ends in a recommendation to buy. They end where a guide should end, with a reader able to walk into any shop and read any label better than they could an hour earlier.
