Question one: does every ingredient carry its own number?
Turn the bottle round and run your eye down the panel. A milligram weight should be sitting beside each name.
Where you meet one lump figure instead, under a heading such as “proprietary cognitive complex”, the evaluation ends on the spot. Whether any single component reaches a researched dose has just been made unknowable to you. Blends are built for that outcome, not in spite of it.
Treat it as a safety gap rather than a disclosure gap. Ask a pharmacist to weigh a ginkgo interaction against a quantity nobody will disclose and you will get a shrug, quite rightly.
Question two: which of these has been tested in people?
Labels flatter their own contents. Part of any list is doing real work, part is bulking out a capsule, and part is there because the name reads well in an ad.
Put it to the seller directly, in writing if the site publishes an address: name the ingredients here that have randomized human trials behind them. Petri dishes and rodents are not an answer — this field is littered with compounds that dazzled in a dish and flatlined in a volunteer.
Silence counts as a reply. So does a change of subject.
Question three: what is the page refusing to tell you?
It reads like the woolliest of these tests. It is in fact the sharpest.
Pick any ingredient in this aisle and a limitation comes attached to it. Dementia rates held steady in the two largest ginkgo studies ever run. Only forty people took part in the curcumin cognition trial. A full twelve months went by before the lutein result appeared. None of that stops being true because a sales page leaves it out.
Omission, then, is a choice somebody made on your behalf about the limits of your information. Spot the choice and you know how much weight the rest of the page deserves.
Question four: what does the payment screen say?
Three facts hide there and nowhere earlier.
- One payment, or a recurring one? A bundle and a rebill are often separated by a single line of gray type.
- Where does the refund clock start, and will they take back a bottle you have opened? Thirty days from the card charge, unopened only, is a change-of-mind policy wearing the word guarantee.
- Whose desk does a refund land on, and can you read the steps now?
Two things that should end the visit
A diagnosis sitting next to an order button. Alzheimer's, dementia or cognitive decline printed within a screen's reach of a purchase link is your cue to leave. Those conditions are not treated or prevented by any dietary supplement sold anywhere, and pitching one as though they were is the exact behavior regulators act on.
A promise faster than the published research. Seven days is not enough time for anything on this shelf to register. Whatever a one-week claim describes, it is either a stimulant or a fiction.
The same four questions, turned on our own label
- Numbers: every ingredient printed at its own weight, no blend anywhere on the panel.
- Human trials: four of the six inputs clear this one — ginkgo, curcumin, lutein, plus the pairing of theanine with caffeine. For bamboo silica and D-Glucosamine the cognitive literature is empty, and we gave each of them a page that says exactly that.
- Omissions: the GEM and Snitz null findings are printed across this site, and so is the recognition-memory test that the positive ginkgo study failed.
- Payment screen: single payments only, nothing recurring, sixty days counted from delivery, part-used bottles welcome back.
Now take the four questions somewhere else and ask them there. A brain supplement comparison you ran yourself beats any ranking somebody else published, and a method that only works on one bottle was never a method.
