Choosing A Cognitive Supplement: Seven Checks

Rankings in this category are almost worthless, because the thing that decides whether a product is any good is not comparable across brands without reading both panels.

A checklist is more useful. Each of the seven below can be answered from the back of a pack, in a shop, without knowing anything about the ingredients beyond what the guide beside this one covers. A label that passes six is worth considering; a label that fails the first one cannot be scored at all.

They are ordered deliberately. The first is the gateway: if a panel hides its amounts inside a blend, checks two through four are unanswerable and the exercise ends. Everything after that is progressively less decisive.

The evidence guide supplies the trial doses that check four is scored against, and every figure in it was verified against a live source.

Three passes, three failures and one partial. A table that came out seven from seven would not have been worth printing.

None of these three can be argued away by a retailer, which is why they are set out here at length rather than softened in a footnote.

Check four fails on all five amino rows and it is the most consequential of the three. The arginine dose-response meta-analysis found nothing below four grams a day against a 200 mg row. Schwedhelm's ladder needed three grams of citrulline twice a day against 200 mg across two salts. The ISSN position stand asks for four to six grams of beta-alanine against 40 mg. Both AAKG trials used twelve grams a day against a 200 mg extract row.

Check five fails on the match between the panel and the name. The amino acids here are the canonical nitric oxide set, sold across the rest of the market as a pre-workout blend. Their literature is vascular: the cardiometabolic review of citrulline and Figueroa's review in older adults describe a circulatory ingredient, and the one study reaching cognition used a different stabilised compound at 1.5 g. Every ingredient on this panel is legitimate; the set is not the set a recall formula would be built from.

Check six fails on two of the four marks. A GMP graphic that names no certifier and a facility registration roundel that names no facility cannot be checked against anything. That is true across most of this category rather than only here, and the quality page reads all four marks one at a time.

Check seven is partial rather than failed because the underlying policy is genuinely good. A hundred and eighty days, opened bottles included, on every pack, with a written procedure and a telephone number, is better than most of this shelf offers. Three circulating return addresses is the flaw, and the procedure on the refund policy page resolves it by requiring the desk to name the destination in writing before anything is posted.

Everything above depends on the first row. An amount against all 7 actives is what let checks two, three and four be answered at all, and a panel that grouped those rows into a blend would have stopped this exercise at question one. Failing check four in the open is a different thing from failing it invisibly.

Check two follows from it and is more than a formality. Distinguishing arginine base from arginine alpha-ketoglutarate, and citrulline hydrochloride from citrulline malate, is disclosure that a shorter panel would have avoided. It is also what makes the extract-weight caveat visible rather than hidden.

Check three passes on a technicality that is worth stating fairly. The panel does not print a total for the actives, and it does not need to: five rows add to 640 mg in one line. A panel with eleven botanical rows at three-figure amounts would be considerably harder work.

Taken together the three passes describe a transparent label. That is a genuine virtue and it is precisely what allows this page to fail the same label on three other questions.

The point of a checklist is that it travels. Run the same seven questions on any pack and the answers sort the shelf quickly.

Most labels in this category fail check one, which ends the exercise immediately and is itself a decisive result. A proprietary blend is a request to take the formula on trust, and there is no version of these seven questions that can be answered about one.

Of those that pass check one, most fail check four for the same reason this one does. The gap between a trial dose and a capsule dose in this category regularly runs between twentyfold and a hundredfold, and the evidence guide sets out the trial figures to score against.

Check five is the one people skip and it is the most interesting. It asks whether the panel belongs to the category the front of the pack names, and a surprising number of formulas in this aisle turn out to carry the ingredient set from another one.

Checks six and seven are about the company rather than the formula, and they are where two otherwise identical panels separate. A refund route in writing with a telephone number behind it is worth more than a badge nobody signed.

Three limits, and a checklist that does not name them is overselling itself.

It cannot tell you what is in the capsule. Every one of the seven checks reads a declaration by a manufacturer, and only an assay by a named laboratory measures the contents. None has been published for the product scored above.

It cannot tell you whether something will work for you. No trial of any finished product in this category is cited anywhere on this website, because this desk could not find one, and individual response to anything at these amounts is unstudied.

And it cannot weigh the checks against each other. Three passes and three failures is a description rather than a verdict, and a reader who values a transparent panel and a long refund window will read the same table differently from one who values dose above everything. The table is there so that both readers see the same facts.

The desk that wrote this checklist sells the product it scored. That is disclosed on the about page and on every page of this website, and it is part of reading this properly.
