GuidesGuides to memory supplements and how to read one
Two long guides and five shorter articles, written for a reader deciding whether to buy anything in this category at all. The first sets out what the published evidence for memory supplements actually looks like. The second is a practical method for reading a label before you pay for what is behind it.
Editorial pages, written to be useful whether or not you buy anything from this counter.
The two long guides
The memory supplement guide
What the randomised evidence in this category looks like once you set the marketing aside: the big ginkgo trial that found nothing, the multivitamin trial that found something, and the three interventions with better evidence than any capsule. Read the guide.
Choosing a memory supplement
A method rather than a recommendation: eight things to look for on a label, in order, with the reason each one matters and what a bad answer looks like. Read the guide.
Shorter articles
Five articles go further on questions the product pages raise and cannot finish. They are collected on the articles index, and each one runs to a couple of thousand words:
- How long MemoHoney takes to work — the honest timeline, and why week one tells you nothing.
- Citrulline for memory: what the trials actually used — the ingredient with the strongest evidence and the widest gap between study and capsule.
- A supplement label with no numbers — what a Supplement Facts panel is for and what its absence costs a buyer.
- Niacin and memory: the one amount you can check — the only ingredient here with a published ceiling.
- What actually helps memory in the evidence — hearing, blood pressure and sleep, none of which is sold on this website.
What these guides deliberately do not do
- They do not rank products. A ranking from a counter that sells one of the entries is a sales page with a table in it, and nobody should believe one.
- They do not recommend a dose. Printing what a trial used is a fact; telling a reader what to take is advice this desk is not qualified to give.
- They do not repeat a claim they cannot source. Every figure in both guides carries a reference number that resolves to a public record.
- They do not pretend the category is settled. The largest trial in it was negative and the most positive result belongs to a multivitamin, which is an uncomfortable pair of facts and is printed anyway.
- They do not substitute for an assessment. Memory that has changed in a way other people have noticed is a clinical question, and no guide changes that.
The first of those five costs this counter more than the other four put together, and it was still an easy decision. Two paragraphs is all anybody needs to tell a guide from a funnel, and a site that blurs the two has spent its credit on every other page as well.
Why a counter publishes guides that do not sell anything
Two reasons, and the commercial one is the smaller of the two. A reader who understands the category buys more sensibly, returns less often and complains about the right things. That is worth something to a seller.
The larger reason is that the alternative is worse. A site that only sells is a site whose every sentence has to be discounted, and a reader who works that out stops believing the parts that are accurate. Publishing the ginkgo trial that found nothing, and the hearing trial that found something, is what makes the ingredients page worth reading.
None of the guides recommends a product, including this one. They set out what is known, how to check it and what a good label looks like, and then leave the decision where it belongs.
The three findings these guides keep returning to
| Finding | Where it comes from | Why it matters here |
|---|---|---|
| Six years of ginkgo did not reduce dementia incidence | A randomised trial in 3,069 adults aged 75 and over | The category's flagship ingredient was tested properly and did not deliver. Plausibility is not evidence |
| A daily multivitamin improved memory | A randomised, placebo-controlled trial in older adults | The one positive supplement result in the category belongs to the cheapest product on the shelf |
| Hearing, blood pressure and sleep have trials behind them | ACHIEVE, SPRINT MIND and the sleep literature | The three interventions with the best evidence for cognitive outcomes are not sold in bottles |
Three findings, none of them flattering to a supplement counter, all of them published and checkable.
Those three sit behind almost every sentence in both guides, and they are the reason the guides are worth the space. A reader who knows them will make a better decision about any product in this aisle, including the one sold here.
They are also why the product pages on this site are shaped the way they are. The ingredients page prints what each trial used rather than what the marketing says, and the who it's for page names the three interventions above in a section of its own.
How to use these guides
If you have not bought anything yet
Read the memory supplement guide first. It takes about ten minutes and it will change what you look for, which is more valuable than a recommendation.
If you are comparing two products
Go straight to the eight checks in the choosing guide and run them on both labels side by side. Most comparisons are settled by the first three.
If you have a bottle already
The articles index has the practical pieces: how long to wait, what the ingredient amounts mean, and how to test something fairly over sixty days.
If you are worried about somebody
Neither guide is the right page. The who it's for page says so plainly and points at what to do instead.
How these pages are kept current
Every guide here carries a review date and every research figure carries a reference number. When a citation is added or changed, the date moves; when a price is read from the seller's page, the date of that read is printed beside it. Nothing is written as though it were timeless, because almost nothing in this category is.
Two kinds of change would rewrite these guides rather than amend them. A randomised trial of a combination memory formula at printed amounts would be the first; nothing of the kind currently exists. A replication of either small positive result cited here — the beta-alanine imaging study or the carnosine trial — would be the second.
Corrections are welcome and are treated as a service rather than a complaint. The address is on the contact page, and a correction goes onto the page itself rather than into a changelog.
