CogniMary Guides: How to Read This Category
Eight guides covering this category rather than only this product: what a brain health supplement actually contains, how to read any label in nine checks, how to take CogniMary, how to verify a bottle, and the four things that matter more than anything in a capsule.

All guides
Eight places to start
Written for someone deciding whether this category is worth their money at all, not only whether this particular bottle is.
The brain health supplement guide
What the category actually contains, which ingredients have human evidence behind them, and the four things that matter more than any capsule.
How to choose a brain supplement
A nine-point checklist for reading any label in this category, including the proprietary blend test and the serving-size trap.
CogniMary ingredients, one at a time
All fifteen actives with their reference doses and their cautions.
CogniMary dosage vs research dosage
Where the declared amounts sit against published intake levels.
How to take CogniMary
Dose, timing, food, missed doses and storage.
Check a genuine bottle
Six checks and lot COG-26/CO-7439.
What each quality seal covers
GMP, FDA-registered, ISO 9001 and what none of them proves.
Reading supplement reviews
How to read any rating, including this one.
The short version
If you read nothing else on this site
Check the serving size before the price
A 60-capsule bottle at two a day is 30 days. The same bottle at one a day is 60 days. Half of all price comparisons in this category fall apart on this one line.
Count how much of the label is in a blend
Add up the ingredients with printed amounts against the ingredients inside a proprietary blend. On this label it is four against eleven.
Look for a guarantee longer than the onset
If reviewers say six weeks and the guarantee is 30 days, the guarantee is decorative.
Rule out the boring causes first
Sleep apnoea, hearing loss, thyroid problems and medication side effects all produce symptoms people blame on ageing. All four are treatable and none is diagnosed by a capsule.

Why these exist
Because the label alone will not answer the real question
A Supplement Facts panel tells you what is in a capsule. It does not tell you whether the category is worth buying into, what a reasonable price looks like, or which of the four things that actually move cognition you might be skipping.
These guides are written to be useful even if you close this tab and buy nothing. That is deliberate. A site that only works if you buy is a sales page wearing a guide's clothes.
Try CogniMary with 60 days to change your mind
Three bottles is $59 each with free US shipping, and it fits inside the 60-day guarantee window better than six does.

What each guide covers
In more detail, so you can pick one
The brain health supplement guide
Starts with the five ingredient families that make up almost every product in this category — B vitamins, cholinergics, herbs, amino acids and antioxidants — and what the human evidence actually supports for each. Then the proprietary blend problem and the one-minute arithmetic that exposes it. Then a price map of the category from budget to certified, and where the meaningful upgrade actually sits. It ends with the four things that matter more than any capsule, which is the part most buying guides leave out because it does not sell anything.
How to choose a brain supplement
A nine-point checklist for reading any label in this category, ordered so that most products fail before you reach the bottom. Serving size before price, declared amounts against hidden ones, the blend arithmetic, mineral forms, standardizations, guarantee length against onset, a human to call, marketing against label, and whether a certificate is available. The list is then applied to CogniMary itself, which passes four, fails four and partly passes one.
Proprietary blends explained
The longest piece on this site about the single biggest limitation of this product. Why US law allows a blend, what the descending-order rule does and does not tell you, and a worked example using a real 635 mg blend across eleven ingredients. It also puts the case for blends fairly, because there is one.
Magnesium forms compared
Why the word in the bracket after magnesium decides how much you absorb. Elemental magnesium and the trap in the arithmetic, the five forms you will meet, what NIH says about oxide specifically, and the honest reason crowded formulas use it anyway.
The five-minute version
If you only have time for one page
Read the dose analysis. It is the page that decides whether this product is worth your money, because it is the only one that compares what is on the label against what the research used.
The short version of that page is this. Four nutrients are declared with amounts and all four are checkable. Folate is comfortably inside its upper limit. Vitamin B12 is safe but far past useful for anyone who absorbs normally. Magnesium is a sensible amount in the least well absorbed common form. Chromium is well above the Adequate Intake with an FDA-acknowledged uncertainty about whether that matters.
The other eleven ingredients share 635 mg and their individual amounts are not published. Common trial doses of just three of them total roughly 820 mg. So some are present below research levels, which ones is unknowable, and the sensible way to buy this product is to value the four declared nutrients and treat the blend as an unpriced extra.
If that reasoning makes the product sound ordinary, that is because it is ordinary, and so is most of what it competes with. Ordinary at $2 a day with a 60-day guarantee is a defensible purchase. Ordinary sold as a breakthrough is not, which is why this site does not sell it that way.
Where these guides stop
Three questions we deliberately do not answer
Whether you personally should take it
That depends on your blood work, your medication and what you are actually trying to fix. A page cannot know any of it and pretending otherwise would be the dishonest part.
Which competitor is better
We sell one product, so any head-to-head we published would be worth exactly what you would expect. The nine-point checklist is the honest alternative: use it on whatever else you are considering.
What dose you should take
The label says two capsules daily. We will not suggest anything different, and anyone who does without knowing your situation is guessing.
What this site will not write
Three articles we could rank for and will not publish
A comparison naming a competitor as worse
We sell one product. Any head-to-head we wrote would reach the conclusion you would expect, and publishing it would be worth more to us than to you.
A doctor-approved page
No doctor approved this site. Adding a stock photograph and a title would take ten minutes and would be the single most dishonest thing on it.
A piece claiming a breakthrough
There is no breakthrough here. It is a mid-market multi-ingredient supplement with four declared nutrients and a blend, and writing it up as anything else would require inventing things.
Reading order
If you are starting from nothing, go in this sequence
The category guide, first
It tells you what is actually in these bottles and, more usefully, what matters more than any of them. Some readers stop here and buy nothing, which is a legitimate outcome.
The nine-point checklist, second
Once you know what the ingredients are, the checklist tells you how to read any label that contains them, including labels belonging to products we do not sell.
The dose analysis, third
Apply the checklist to this specific product. It is the page that decides whether this bottle is worth your money, and it is the least flattering page on the site.
The pricing page, last
Only once the first three have convinced you the product is worth considering at all. Reading price first is how people end up buying six bottles of something they have not assessed.
Who writes these
The same desk, with the same rules
Every guide on this site is written by the CogniMary Editorial Desk, which is an organisation rather than a named individual, and which is defined that way in this site's structured data for exactly that reason. No clinician reviewed them and none is credited.
The rules are the same as the product pages. Sources are opened before they are cited, anything unknown is marked unknown, and the parts that argue against a sale get the same space as the parts that support one. The category guide spends four paragraphs on things that are better uses of your money than any supplement, which is a strange thing for a supplement site to publish and is the point.
