Choosing A Memory SupplementChoosing A Memory Supplement: Eight Checks Before You Pay
Eight things can be checked before any money changes hands, and most buyers check two of them.
The ingredient list, the amounts, the format, the evidence behind each name, what the seals mean, the refund window, the channel and the claims. This checklist runs through all eight in the order that saves the most time, then scores this counter's own product against them.
Nothing here is specific to one brand until the last section, which is where this product is scored in public, including the two checks it does not pass.
Check one: is every ingredient named?
A proprietary blend pools several ingredients behind a single total. It is legal, it is common, and it means you cannot know whether the total is mostly the expensive ingredient or mostly the cheap one.
The rule of thumb is simple. If the label names every ingredient separately, the manufacturer has chosen transparency about composition. If it gives you a blend name and one number, it has chosen the opposite, and the reason is almost never to protect a formula from competitors who can pay a laboratory to analyse it anyway.
- Every ingredient listed on its own line
- No phrase of the form “proprietary blend” followed by one figure
- Latin binomials for botanicals, because common names cover several species
- The plant part for a botanical: root, leaf and seed are different products
Check two: is there a number beside each name?
This is the check that separates a label you can compare from one you cannot, and it is the one most buyers skip.
A name without an amount tells you an ingredient is present. It does not tell you whether there is enough of it to do anything, and in this category the gap between a token quantity and a studied quantity is frequently a factor of a hundred.
Where a panel does print amounts, the useful next step is to look up what the trials used. A label claiming an ingredient at 50 mg where the research ran at 500 mg has told you something important, and it told you honestly.
Sometimes the advertising names the ingredients and leaves the amounts to a panel you only see once the bottle arrives. Look for the label image before paying: sellers often show the full wrap somewhere on the page, and the panel on it is the regulated statement, which beats every line of copy around it. If no panel is shown at all, the order line and a certificate of analysis are the only routes left.
Check three: does the format fit the amounts?
A capsule is a container with a hard physical limit. A size 0 shell holds roughly 400 to 900 mg of powder depending on density; a size 00 holds more, and a gummy holds less than either once the sugar and gelling agent are accounted for.
So a label is worth reading twice when it names several ingredients whose trials ran in grams. Two grams of one amino acid is already more than a capsule can carry, and five such ingredients in one capsule is arithmetic that does not come out. Synergy is the word usually offered in place of that arithmetic, and it is not a quantity.
This check costs nothing and it is the fastest way to tell an ambitious label from an achievable one.
| Format | Roughly holds | Suits |
|---|---|---|
| Size 0 capsule | 400 to 900 mg of powder | Vitamins, minerals, standardised botanical extracts |
| Size 00 capsule | 600 to 1,300 mg | The same, with a little more room |
| Tablet | Up to about 1,500 mg | Compressible material, at the cost of disintegration time |
| Gummy | Under 500 mg of active material in a 2 to 3 g sweet | Vitamins and small actives, never grams of an amino acid |
| Powder or scoop | 5 to 15 g | The gram-scale amino acids, which is where those trials were run |
Approximate working figures for reading a label, not manufacturing specifications.
Check four: what has each ingredient actually been tested for?
An ingredient with published research behind it is not the same as an ingredient with published research behind it for the thing you are buying it for. That distinction does most of the work in this category.
Take citrulline. It has a solid literature: blood pressure, repeated sprints, cerebral blood flow during interval training. All real, all measured, and only the third is within reach of a memory claim.
Or ginkgo, which is the most-sold botanical in this category. A six-year randomised trial in over 3,000 older adults found no reduction in dementia incidence. That is a large, expensive, well-run trial reporting a null result, and it is rarely quoted on a sales page.
- Look for the population: trained athletes and older adults with memory complaints are different groups
- Look for the outcome: a plasma level is not a cognitive test
- Look for the amount, and compare it with what the format can hold
- Look for the null results, which are the ones nobody advertises
Check five: what do the seals on the bottle mean?
An emblem wall looks like testing and almost never is. Each mark is a statement about something specific, and the specific thing is usually the building rather than the bottle.
| Emblem | What it is a statement about |
|---|---|
| GMP | The facility's procedures and records, audited by whoever certified it |
| FDA registered facility | A registration every US food facility files. The FDA does not approve dietary supplements |
| Made in the USA | Where the bottle was filled, not where the raw material was made |
| Non-GMO | The source material |
| Natural | Nothing testable. The word has no fixed legal definition here |
| Doctor formulated or developed | That the seller says a clinician was involved. Ask who |
| Gluten free, dairy free | Formulation claims. For coeliac disease, ask for the tested figure in parts per million |
| Third-party tested | The only one that might mean finished-product testing. Ask which programme, and for the certificate |
Only the last row can be a statement about what is inside the capsule, and only if the programme is named.
Checks six, seven and eight: the window, the channel and the claims
Six: read the refund window, and note where it starts
A window counted from purchase is shorter than one counted from delivery, because processing and transit come out of it. Then check whether the seller asks for a minimum period of use first: thirty days of use inside a sixty-day window leaves less room than the headline suggests.
Seven: buy through a channel that creates a record
An order ID in the seller's system is what makes a refund route exist. A genuine bottle from a marketplace reseller carries no such record, and storage history on a dated product is not a triviality.
Eight: read the claims for what they are allowed to say
A dietary supplement may make structure and function claims: supports, helps maintain, contributes to. It may not claim to treat, prevent or cure. A label that stays inside those words is behaving; a sales page that steps outside them is telling you something about the seller.
Scoring MemoHoney against this checklist
The checklist applied to this counter's own product, including where it loses.
| Check | Result | Why |
|---|---|---|
| 1. Every ingredient named | Pass | All seven panel lines are named individually. Nothing is pooled behind a blend total, though the advertising names only six |
| 2. An amount beside each name | Pass | The Supplement Facts panel prints a figure for every line, from 200 mg of arginine to 7.5 mg of niacin |
| 3. Format fits the amounts | Fail | The capsule carries 640 mg of amino acids across five lines; the trials behind them used 2.4 g to 12 g a day of a single ingredient |
| 4. Evidence for the right thing | Mixed | Real trials for all six named ingredients, one cerebral blood flow measurement, and no trial of this formula or of these ingredients together |
| 5. Seals understood | Pass | Nine emblems, each audited on the testing page. None is a finished-product test and the site says so |
| 6. The refund window | Pass, with a caveat | 60 days, counted from purchase, with 30 days of use requested first. Real, and shorter than it looks |
| 7. The channel creates a record | Pass | An order ID in the seller's system, and a telephone line that can search it |
| 8. Claims stay inside the rules | Pass | Memory support, focus, clarity and energy. Structure and function statements throughout |
Six passes, one fail and one mixed. The fail is the one fact the whole site turns on: the label is honest about its numbers, and its numbers are a fortieth to a sixtieth of the studied ones.
That is the honest score, and it is printed here rather than on a page nobody reaches. What it means for a buyer is that this product is a reasonable bet on the routine, the transparency of the label and the refund window, and a poor bet for anybody expecting the results of trials that used gram amounts. The amounts comparison is where that argument is made in full.
