Twenty-one ingredients. Fifteen milligrams.
Cognizil is a one-millilitre daily liquid. Its label publishes a full Supplement Facts panel — and puts twenty-one ingredients inside a single 15.47 mg figure without saying how it divides.
The brief we were given said this product had no published panel and no phone number. The bottle has both. Here is what else the two disagreed about.
Split evenly that is 0.737 mg each. It is not split evenly, and the label does not say how it is split.
One dropperful a day, 30 ml to a bottle, 30 days. The panel quantifies one thing: 7 micrograms of chromium. Everything else shares a 15.47 mg proprietary blend — an average of 0.737 mg each if it were split evenly.
Grant every assumption in the product’s favour, including the label’s own 20:1 extract claim, and fourteen of the sixteen ingredients with a researched dose still cannot reach it. Packs run from $49 to $79 a bottle.

- Every dose claim carries its citation

Two things here are better than the written brief implied. It said no typed milligram list existed and told us not to invent a panel; the artwork contains a complete one. It said there was no public phone number; the bottle prints one. Both are published here.
Fifteen milligrams, twenty-one ways
This is the whole argument, and it is division.
This chart is not an estimate of what is in the bottle. It is the most that can be, with two generous assumptions granted at once — and the conclusion survives both.
Fourteen of the sixteen ingredients with a verified researched dose cannot reach it, even here. The two that do — grape seed and guarana — reach only the bottom of their studied ranges, and only because we credited the extract multiplier in full.
The shortfalls run from 1.5× at the best to 6,787× at the worst. That is four orders of magnitude, which is why the default scale on this chart is logarithmic: on a linear scale the fourteen short bars would be a single indistinguishable smear at the far end.
Added the other way round: the lowest researched dose of every ingredient that has one totals 25.9 grams. The blend is 15.47 milligrams. It would need to be about 1,673 times larger.
Nothing on that chart estimates what is in the bottle. It grants the most generous reading the label allows and shows that the conclusion does not depend on being harsh. The full working is on the best case page.

That is the whole panel, transcribed from the supplied label wrap. It is unusual to be able to publish one in this category and it deserves the credit before anything else on this site argues with it.

The fourth figure is the most generous reading available: every ingredient at its maximum, with the label’s own extract multiplier granted in full.
Pros and cons
What this label does well
- A full label wrap with a real Supplement Facts panel
- Three pack prices, printed plainly, with a per-bottle figure
- A 180-day window on the sales page kits, which is unusually long
- A distributor name, a street address, a phone number and an email on the bottle
- An Other Ingredients line, so the sweeteners and preservative are disclosed
- Extract ratios printed, which most labels in this category do not bother with
- The chromium row’s arithmetic is correct: 7 mcg is exactly 20% of the Daily Value
What it does not
- Twenty-one ingredients share 15.47 mg with no split disclosed
- Fourteen of the sixteen with a researched dose cannot reach it, best case
- Seven of the twenty-one are amino acids dosed in grams in every trial
- Raspberry ketones have no human trial at supplement doses at all
- Grapefruit seed is on the panel, and the published analytical work on commercial grapefruit seed extract raises a serious question
- Gymnema, forskohlii, African mango and cayenne are metabolic ingredients on a memory label
- No independent testing of any kind was supplied
Our editorial score
A full label wrap with a Supplement Facts panel, a serving size, an Other Ingredients line, a distributor address, a phone number and an email. It is a real label, and it is better than the brief implied.
One dietary ingredient is quantified. Twenty-one share a single 15.47 mg figure. This is the lowest score we can give.
A one-millilitre serving carrying twenty-one extracts and amino acids. Fourteen of the sixteen with a researched dose cannot reach it even on the most generous reading of the label.
Panax ginseng, guarana, grape seed and L-tyrosine all have real literature. Raspberry ketones have no human trial at all, and the guarana meta-analysis called its own pooled effect less than trivial.
Gymnema and forskolin are metabolic ingredients. African mango is a weight-loss ingredient. Astragalus is studied in kidney disease. On a memory label.
Grapefruit seed is on this panel, and the published analytical work on commercial grapefruit seed extract found synthetic preservatives doing the work in the products tested. We cannot say what is in this one, and neither can the label.
Three pack prices, printed plainly, with a per-bottle figure. After two builds with no price at all, this is a genuine strength.
A 180-day window on the sales page kits is unusually long, and there is a phone number on the bottle. There is no retailer order desk.
Eight supplied entries. Two sentences between them. Four of each, word for word.
Nine rows. This product prices better than either of the labels we looked at before it, and doses worse than both.
How to take it
The label’s instruction is three sentences: “Shake well before each use. Take 1 dropperful daily. Place in mouth and swallow.”
Shake it, properly
This is a suspension of plant extracts in water. Anything that settles has to be redistributed or the first and last doses in a bottle are not the same thing. This instruction is doing real work.
One dropperful is one millilitre
That is what the panel measures. If your dropper has graduations, use them; if it does not, fill it to the same point every day.
Pick a time and keep it
The label does not specify one. Attach it to something you already do without thinking — a habit is a more reliable cue than an hour.
Store it away from heat and light
The label says so, and for a liquid of plant extracts that is more than boilerplate. A cupboard, not a windowsill.

Those are the prices printed on the sales page supplied to this website. No single-bottle price was supplied, and no shipping figure was either. The day counts and the cost a day are ours, and they are division: 30 ml a bottle, 1 ml a day, 30 days a bottle.
What do Cognizil reviews say?
The seller supplied a set of review figures. We publish them as the seller’s figures and audit them, because the eight supplied entries use two sentences between them — four of each, word for word.
No verified customer review appears anywhere on this site, and no review or rating schema is emitted on any page, so no star rating from this site will appear in a search result.
Common questions
What is Cognizil?
A liquid dietary supplement sold in the United States by Gocognizil as an authorised Cognizil retailer. The bottle holds 1 oz / 30 ml, the serving is 1 ml taken as one dropperful, and the label counts 30 servings to a bottle. The front prints “ADVANCED MEMORY SUPPORT*”.
Does Cognizil publish a Supplement Facts panel?
Yes. The written brief supplied with this build said a typed milligram list was not on the sales page and told us not to invent a panel. The artwork in the same folder contains a full label wrap with a complete panel on it. We transcribed the panel that exists rather than inventing one, and the supplement facts page shows it in full.
What is in the blend?
Twenty-one ingredients sharing 15.47 mg: maca, African mango, grape seed, guarana, eleuthero, astragalus, green tea, gymnema, forskohlii, cayenne, grapefruit seed, panax ginseng, raspberry ketones, L-glutamine, L-tyrosine, L-arginine, beta alanine, monoammonium glycyrrhizinate, GABA, L-tryptophan and L-carnitine HCl, in that printed order.
How much of each is in a serving?
Not published, and not legally required to be. What can be worked out is an upper bound for each position, because the law requires blend ingredients to be listed heaviest first. The best case page does that and then grants the label's own extract-ratio claims on top.
Is 15.47 mg a lot?
No. Split twenty-one ways it averages 0.737 mg each. For comparison, the lowest dose used in the research behind these ingredients adds up to about 25.9 grams — roughly 1,670 times the whole blend.
Is there evidence any of this improves memory?
For a few ingredients there is real literature, and for several there is none in humans at all. Panax ginseng's 2024 meta-analysis found a small effect on memory and nothing on overall cognition, attention or executive function. Guarana's meta-analysis called its pooled effect less than trivial. Raspberry ketones have no human trial. It is all on the ingredients page with citations.
Can 15.47 mg do anything?
For a handful of very potent compounds a milligram-scale dose is meaningful. None of the twenty-one ingredients here is in that category: the amino acids are dosed in grams, the botanicals in hundreds of milligrams. Fourteen of the sixteen with a researched dose cannot reach it even on the most generous reading of this label.
Does the 20:1 extract claim fix that?
It helps two ingredients and does not rescue the rest. Granting the multiplier in full, grape seed and guarana reach the bottom of their studied ranges. The other fourteen still fall short, by between 1.5 times and nearly 6,800 times.
