Choosing A Memory Supplement

How to choose a memory supplement, and how this one scores

Twelve questions to ask of anything on this shelf, from whether the ingredients are named to whether the amounts reach the amounts the trials used. Then the same twelve applied to the product this desk sells, which passes seven, fails three, and is unknown or partial on two.

A checklist that is worth more than any single product review, because it survives the next product.

The checklist

Twelve questions to ask of any memory supplement

The questionWhy it matters
Is every ingredient named?A proprietary blend title hides the list. Six names printed openly is better disclosure than most of this shelf offers.
Is an amount printed beside each name?This is the one that separates a serious label from a decorated one. Without amounts, no comparison with any trial is possible.
Is the serving size stated, and does the count match it?A 30-capsule bottle at one a day is a month. A 60-count bottle at two a day is also a month, and the two look identical on a shelf.
Are the named ingredients studied for the outcome being sold?This is where most memory formulas fail. An ingredient with a vascular trial behind it is not an ingredient with a memory trial behind it.
Do the amounts, where given, reach the trial amounts?A gram-scale ingredient at a milligram-scale amount is a name on a label rather than a dose.
Is there a single unit to try?A one-bottle option lets a buyer test the product for a month. Its absence raises the entry cost and shifts the risk onto the refund window.
Is the refund window stated in days, and from what date?From purchase is shorter than from delivery. A policy that does not say which is doing a buyer no favours.
Is a human contact route published?A telephone number that a person answers is worth more than a contact form, and it is the fastest route to a refund on every offer this desk has seen.
Can a batch be named?A lot code on the bottle that matches a lot code on the listing is the minimum. A published assay against the label would be better.
Does the seller publish who wrote the pages?An editorial desk with a published method is checkable. An invented medical reviewer with a stock photograph is not.
Are the claims structure and function claims?Support and help are legal. Treat, cure and prevent are drug claims, and a supplement making one is telling you something about itself.
Does anything on the page argue against the product?A page with no weaknesses on it has been written by somebody who wants a sale more than a returning reader.
The decisive question

Why amounts are the question that decides the rest

If only one of the twelve can be checked, make it the second one.

An ingredient name on a label tells a reader that a compound is present. It says nothing about how much, and in this category how much is nearly the whole question. The trials that found something with citrulline used 3,000 mg and 6,000 mg a day. The one randomised human trial of arginine alpha-ketoglutarate used 10,000 mg a day. A capsule holds well under 1,000 mg of powder in total.

So a label naming four amino acids with no amounts beside them is not necessarily hiding anything sinister. It is simply leaving the only question that matters unanswered, and a buyer who does not ask it will compare two products on the length of their ingredient lists, which is precisely backwards.

Analytical work on supplement labelling has repeatedly found content that differs from what a label declares, which is why the published assay in question nine is the strongest signal on this list and also the rarest. One such analysis is cited at the foot of this page.

The practical version of question two

Multiply the label amount by the servings per day and compare it with the amount the trial used. If the label does not give an amount, the comparison cannot be made and that itself is the answer.

The score

The same twelve questions applied to this product

The questionResultWhy
Is every ingredient named?PassSix names printed on the artwork with no blend title anywhere.
Is an amount printed beside each name?FailThe supplied artwork carries no Supplement Facts panel. The container carries a printed one, which is the document.
Is the serving size stated, and does the count match it?PassOne capsule daily, 30 to a bottle, which is a clean month.
Are the ingredients studied for the outcome being sold?FailFour of six are nitric-oxide compounds studied for blood flow, blood pressure and muscle work rather than memory.
Do the amounts reach the trial amounts?UnknownNo amounts are published in the artwork, and a capsule cannot carry gram-scale amounts of four ingredients.
Is there a single unit to try?FailTwo bottles at $158 plus shipping is the smallest possible purchase.
Is the refund window stated in days, and from what date?Pass60 days from the date of purchase, stated plainly, on every pack size.
Is a human contact route published?PassA telephone number, +1 (302) 200-3480, on every page of this site.
Can a batch be named?PartialA lot code and a certificate reference exist. No assay against the label is published.
Does the seller publish who wrote the pages?PassAn editorial desk with a six-step published method and a corrections address.
Are the claims structure and function claims?PassAll five supports the seller prints are structure and function statements.
Does anything on the page argue against the product?PassEvery page here carries a quarantined section that does.

Seven passes, three failures, one partial and one unknown. A desk that scored its own product twelve out of twelve would be telling a reader something about itself rather than about the product.

The standard

What a better label on this shelf would look like

Not a hypothetical. Every element below exists on products already sold in this category, and a buyer who insists on them will end up with a shorter shortlist and a better one.

It would print an amount beside every name, in milligrams, per serving. It would state the serving size and the servings per container in the same place. It would name the form of each compound, because citrulline malate and citrulline HCl are not interchangeable by weight. It would publish a certificate of analysis from a named laboratory, dated and tied to a lot code. And it would offer one unit, so the first purchase costs a month rather than two.

None of that requires a new trial, a new ingredient or a bigger marketing budget. It is disclosure, and disclosure is cheap.

  • An amount in milligrams beside every ingredient name.
  • The serving size and servings per container, stated together.
  • The specific salt or form of each compound.
  • A dated certificate of analysis from a named laboratory, tied to a lot code.
  • A single-unit purchase option.
  • A refund window stated in days and counted from a named date.

The Memodyne bottle, front label facing, 30 capsules

The checklist is printed, and Memodyne scores seven of twelve

Seven passes, three failures, and both lists on the same page. That is the information a buyer needs, and the sixty-day window is what carries the risk while they use it.

Lot MEM-26/MA-2612 · one capsule a day, 30 to a bottle · ships from the United States

60-day money-back guarantee

Two months to decide, and the seller asks you to spend one of them taking it

The window opens on the date of purchase, not the date the parcel arrives, so it is the shorter of the two clocks and the one worth counting from. The seller's own terms ask for 30 days of use before a claim, which leaves roughly a month to decide and act. Claims are opened by telephone with the order ID in hand; the refund policy sets out what follows, and the guarantee page works through the arithmetic pack by pack.
