Choosing A Formula

Choosing A Nerve Supplement

Eight checks, each worth points, all of them runnable on a bottle in a shop in about two minutes. The method is published in full before it is used, and the last section runs it on the product this website sells and prints the total without adjusting the scoring to suit.

A scoring card for a shelf where almost nothing carries the ingredients the research is about.

The method

Why a scoring card beats an opinion

What this card measures, what it does not, and why the weights are published first.

Most advice about choosing a supplement amounts to a list of adjectives: look for quality, look for transparency, look for a reputable brand. None of those can be checked while holding a bottle, which is where the decision is actually made.

Eight yes-or-no checks can be. Each one below is answerable from the panel and the packaging alone, without a phone, and each is worth a fixed number of points so two products can be compared without an argument about which adjective matters more.

The scoring is deliberately blunt. It rewards information over marketing, and it punishes a label for hiding what it could have printed. That is a value judgement and it is stated here rather than smuggled into the weights.

The card

The eight checks, and what each is worth

Eight rows, sixteen points, and a column telling you where on the bottle each answer is.

#The checkPointsHow to answer it in a shop
1Does the panel print an amount for every ingredient?3Turn the bottle over. Amounts in the right-hand column, or a blend total
2Does it carry any of the four trialled ingredients?3Alpha-lipoic acid, benfotiamine, acetyl-L-carnitine, B12
3If it does, is the amount near the trial dose?2600 mg, 300–600 mg, 1,500–3,000 mg respectively
4Does it name the plant part and the species?2“Root”, “bark”, a latin binomial in brackets
5Is B6 absent, or present at a modest amount?2Look for pyridoxine and a Daily Value in the hundreds of per cent
6Is the serving size and month count honest?2Capsules per bottle divided by capsules per serving
7Does the other-ingredients line tell you about the shell?1Gelatin, vegetable cellulose, or nothing said
8Is a lot code and a contactable seller printed on it?1A lot, a best-before, and an address or telephone number

Sixteen points available. The first two are worth three because they are the two that decide whether anything else on the card can be answered at all.

Check three only scores if check two scored, which is why it is worth two rather than three: a label carrying none of the four cannot be marked down twice for the same thing.

Check five is the one most shoppers would not think of, and it is on the card because high-dose B6 causes the symptom this shelf is sold for. The nerve supplement guide sets out the evidence behind it.

Scoring

Reading a total once you have one

Four bands, and the limit of what any of them can tell you.

TotalWhat it meansWhat to do with it
13–16A label that tells you nearly everything and carries the researchRare on this shelf. Compare it against a second one on price per day
9–12Informative, but missing either the ingredients or the amountsWorth buying if the missing half is the one you care least about
5–8A label you can read but cannot checkJudge it on something other than the research, and know that is what you are doing
0–4A label that has printed the minimumNot necessarily a bad capsule. An unknowable one

A total is a measure of how much a label tells you. It is not a measure of whether a capsule works, and no card made of eight yes-or-no questions could be.

That last line in the note is the honest limit of this method and it needs saying twice rather than once. Everything on the card is about information. A product could print every amount, name every species, and still do nothing at all; another could hide behind a blend total and contain something useful.

The card is still worth running, because information is the only thing a shopper actually has access to. What it buys you is the ability to tell what you know from what you are assuming, and on this shelf those two are usually tangled.

Honest critique

Four things on a label that score nothing

Four label features that feel like evidence and score zero on this card.

A seal with no organisation named

A roundel reading “laboratory tested” or “quality assured” with no certifying body on it is a graphic. It scores zero on this card because there is nothing behind it to check.

A regulator's logo on a filing

A facility registration is a statement that a factory has filed. It is not approval of the capsule, and no dietary supplement holds that. The regulator's own answers say so directly.

A milligram figure on the front of the bottle

The front is marketing. A large number there with no matching row on the panel is a design decision rather than a declaration, and the panel is the part that has to be true.

A percentage with no reference point

“Standardised to 10 per cent” needs a weight before it means anything. Ten per cent of a figure the label does not print is not information.

None of these is fraud and this guide is not calling any of them that. They are marketing shapes that look like data, and the reason to name them is that they occupy the exact part of a label a careful shopper is looking at. The testing page on this site audits the four seals on the pack it sells, including the two that name nobody.

Honest scoring

Running the eight checks on Nervelin

The same eight checks, run on the product this website sells, with the total printed as it came out.

#The checkThis labelPoints
1An amount for every ingredient?No. One figure, 1000mg, for all 90 of 3
2Any of the four trialled ingredients?No. None of the four appears on this panel0 of 3
3Near the trial dose?Not applicable, check two scored zero0 of 2
4Plant part and species named?Yes, on seven of the nine, in brackets, including Cinnamomum verum and Momordica charantia2 of 2
5B6 absent or modest?Absent. No pyridoxine on this panel2 of 2
6Serving size and month count honest?Yes. Two capsules, 60 a bottle, thirty servings, stated2 of 2
7Shell declared?Yes. Gelatin capsule, in the other-ingredients line1 of 1
8Lot code and a contactable seller?Yes. Lot NER-26/GE-1959, and a desk on +1 (302) 200-34801 of 1

Eight of sixteen. The card is published above and the arithmetic is in the right-hand column.

Eight of sixteen puts this label in the third band: readable, and not checkable. Both halves of that are true and both are worth stating in the same sentence.

What it loses is the whole of the first six points, and for one reason. The panel declares 1000mg for 9 ingredients together, so no amount can be read for any of them, and none of the four ingredients with controlled trials in this condition is among the nine.

What it gains is everything a label can be asked for once that is accepted. Seven of the nine names carry a species and a plant part. The serving arithmetic is printed and correct. The shell is declared. There is a lot code and a desk that answers. Plenty of bottles on this shelf score lower.

The score in four lines
  • Zero on amounts, because one figure covers nine ingredients.
  • Zero on the trialled ingredients, because none of the four is here.
  • Full marks on species, plant parts, serving arithmetic and the shell.
  • Full marks on traceability: a lot code, a certificate reference and a contactable desk.
Honest limits

Two questions the card cannot answer

What a scoring card is structurally unable to tell you, said before you rely on one.

The first is whether the capsule does anything. Nothing on an eight-point card touches that, and on this product nothing else does either: there is no controlled trial of this formula, and the nine ingredients have their research in other conditions.

The second is what it costs, which this website cannot tell you because the price sits at the marketplace checkout and was not readable on 19 September 2026. Price per day is the comparison worth making once you have two scores, and it is the one figure that has to come from the checkout screen.

Both of those belong on the product pages rather than in a guide. The reviews page handles what the buyer figures can and cannot carry, and the pricing page explains why no number is printed on it.

Run the card on two bottles and the comparison becomes concrete rather than a matter of impression. Run it on one and you at least know what you are choosing to accept.

Returns and the order desk

The window that covers this purchase is the marketplace listing’s own

The seller sets the return window and prints it on the listing you buy from, so read it there before you pay rather than taking a number from a website. To start a return, call the order desk with your order ID and follow the steps on the refund policy page: return postage is the buyer’s, and the parcel needs your full name, email and order ID inside it.
