Maxorin label facts: three rows, ten findings

By the Maxorin Editorial Desk · Last updated September 24, 2026 · how we check facts

This is the Supplement Facts panel from the Maxorin label, transcribed row by row. Nothing has been added, reordered or corrected. Tap any row in the panel below to read what that row’s research file actually says.

The panel gives a serving size of 1 capsule and 30 servings. It has three rows: niacin 20 mg at 125%, zinc 11 mg at 100%, and a Proprietary Blend of 570 mg naming six ingredients with no individual amounts. Both percentages are correct. The blend is about 95% of the capsule by weight.

Tap any row

Percent Daily Values are based on a 2,000 calorie diet. * Daily Value not established.

Two things are worth noticing before the contents. The first is that the two rows carrying a percentage are the two the FDA requires to be itemised, because they have established Daily Values — and both percentages check out. The second is that the third row is larger than the first two put together, eighteen times over, and carries an asterisk instead of a figure.

The Maxorin label: suggested use, caution and storage text, the distributor block, the front panel, and the Supplement Facts panel showing niacin, zinc and a 570 mg proprietary blend — The full Maxorin label: suggested use, caution and storage on the left, the front panel in the middle, and the Supplement Facts panel on the right.

Ten findings, in full

Each is a statement about this label, checked against a source linked at the foot of the page. They are ordered by how much they should change a decision.

01Ninety-five per cent of the formula is inside a proprietary blend with no amounts.

The capsule holds 601 mg of declared material. 570 mg of it — about 95% — sits in a single row headed Proprietary Blend, listing six ingredients and not one amount. This is lawful: the FDA requires the blend’s total weight and its ingredients “in descending order of predominance by weight”, and only ingredients with an established Daily Value must be itemised individually. The label follows that rule exactly. The consequence is that the two ingredients you can check are the two smallest, and the six you cannot are everything else.

02The descending-order rule still forces a ceiling on every ingredient. Here they are.

If six items are listed in descending order of weight and total 570 mg, then the item in position n cannot weigh more than 570 divided by n — otherwise the items at or above it would already exceed the total. That gives: L-citrulline at most 570 mg, L-carnitine at most 285 mg, pine bark at most 190 mg, maca at most 142.5 mg, grape skin at most 114 mg, saffron at most 95 mg. None of those six numbers is printed on the bottle and all six are forced by it. They are ceilings rather than amounts, and the true figures could be far lower.

03The L-carnitine ceiling is a quarter of the lowest studied dose — of something the body already makes.

The NIH is unusually direct about carnitine: “Healthy children and adults do not need to consume carnitine from food or supplements because the liver and kidneys synthesize sufficient amounts to meet daily needs.” Where it is studied for exercise, the doses are 1 to 4 grams, and the NIH’s summary of that literature is that “the evidence on supplemental carnitine’s effectiveness for performance enhancement is mixed, and additional investigations are needed”. The ceiling here is 285 mg — at most a quarter of the lowest of those doses, and possibly a great deal less.

04The niacin percentage is right, and the form of niacin is not stated.

Vitamin B3 (as Niacin) — 20 mg — 125% is arithmetically correct: the FDA’s Daily Value is 16 mg. It is also below the NIH’s Tolerable Upper Intake Level of 35 mg. What the row does not say is which compound it is. Nicotinic acid and niacinamide are both “niacin” and only one of them flushes; the NIH puts the threshold at “thirty to 50 mg or more nicotinic acid”. At 20 mg neither form is likely to cause trouble, which is why this is finding 4 rather than finding 1 — but a naming convention that covers two different compounds should name the one in the bottle.

05The zinc percentage is right too, and the form is the least absorbed of the common ones.

Zinc (as Zinc Oxide) — 11 mg — 100% matches the FDA’s Daily Value of 11 mg exactly. The NIH compares the forms plainly: absorption from zinc citrate or gluconate is “approximately 61% in young adults; the absorption from supplements that contain zinc oxide is 50%”. Every zinc product quotes content rather than uptake, so the label is not doing anything unusual — it is simply that of the common forms, this is the one on the wrong side of that comparison.

06It is grape skin, not grape seed — and the monograph is about the seed.

The blend names Grape (Vitis vinifera) Skin Extract. Naming the plant part is good practice and most labels in this trade do not bother. It also means the research file a reader is most likely to find does not apply: NCCIH publishes on grape seed extract, a different part of the plant with a different chemistry. Nothing here says the skin does not work; it says that the obvious place to look it up is about something else, and this desk found no monograph for the skin at the bodies it uses.

07Four of the six blend ingredients have no monograph at the sources this desk reads.

L-citrulline, pine bark extract, maca root and saffron stigma extract return nothing at the NIH Office of Dietary Supplements or NCCIH under the names printed on this label. That is a statement about what can be cited here, not a verdict on the ingredients: absence of a monograph is absence of information. Combined with the blend, it means four of the six rows have neither a published amount nor a citable file — so nothing at all can be said about them, in either direction.

08No standardisation is printed for any of the four botanicals.

Pine bark, maca, grape skin and saffron are all extracts, and an extract without a standardisation figure is a weight of unspecified concentrate. A standardisation names the compound the research measures and the proportion of the extract that is it, which is what lets a reader convert a label figure into a research figure. None of the four carries one. The label does name the species and the plant part for every botanical, which is better than most — it is the next column that is missing.

09The distributor is a city, a state and a zip. There is no street.

The label reads Distributed by: Maxorin, Aurora, CO 80011, with a telephone number and an email. There is no street address, so there is nothing to post a letter to. This desk has now seen that same city and zip — Aurora, CO 80011 — on the distributor block of an unrelated brand in a different category, which is worth recording without drawing a conclusion from it. Separately, a print code reading EVRB_420_01_080626 appears along the edge of the artwork; it is a production code for the label file, not an ingredient and not a claim.

10The marketing template is shared with an unrelated brand, and the review block is layout copy.

A second pack reached this desk in the same batch, for a chewable oral-health tablet from a different company. Its “Inside” graphic is the same six boxes in the same arrangement with the same six labels as this product’s, and its “How it works” graphic is the same three numbered steps. Only the colour and the bottle change. The review blocks match too: 4.5 out of 5 here against 4.6 there, 1,125 written reviews against 925, both with a “most wait 3–6 weeks” line and eight named customers. This site publishes no rating, no review count and no testimonials.

The ceiling table

The blend hides six amounts. It does not hide everything, and this is the part of the label that repays arithmetic.

The six blend ingredients, and what each cannot exceedSix ingredients, 570 mg, listed in descending order of weight

01L-CitrullineAn amino acid. Listed first, so it is the largest item in the blend.at most 570 mg

02L-CarnitineAn amino-acid derivative the body makes for itself.at most 285 mg

03Pine bark extractPinus pinaster — bark. No standardisation printed.at most 190 mg

04Maca root extractLepidium meyenii — root. No standardisation printed.at most 142.5 mg

05Grape skin extractVitis vinifera — skin, not seed. No standardisation printed.at most 114 mg

06Saffron stigma extractCrocus sativus — stigmas. No standardisation printed.at most 95 mg

None of those six figures is printed on the bottle. Every one of them is forced by the FDA’s own rule for proprietary blends, which requires the ingredients to be listed “in descending order of predominance by weight”. If the six are in descending order and they total 570 mg, then the item in position n cannot weigh more than 570 divided by n — because if it did, the n items at or above it would already exceed the total. So the second-listed ingredient cannot exceed 285 mg, the fourth cannot exceed 142.5 mg, and the last cannot exceed 95 mg. These are ceilings, not amounts: the true figures are at or below them, and could be far below.

Why a ceiling is still worth having

Because it can only be wrong in one direction. If an ingredient’s ceiling is already below the amount the research used, the real figure — whatever it is — is below it too. That is exactly the situation with the L-carnitine row, and it is a conclusion the label cannot escape by keeping the number private.

What is checkable, and what is not

The clearest way to see the shape of this panel is by weight.

601 mg, and where it sitsTwo itemised rows against one proprietary row.

Zinc, itemised and checkable11 mg

Niacin, itemised and checkable20 mg

Proprietary blend, six ingredients, no amounts570 mg

10 mg30 mg100 mg300 mg600 mg

A capsule declares 601 mg of material. The two rows a buyer can actually check — niacin and zinc — come to 31 mg between them, about 5% of the total. The remaining 570 mg, roughly 95%, is a single row naming six ingredients and no amounts. Nothing here is against the rules: the FDA requires an individual weight only for ingredients with an established Daily Value, which is precisely why niacin and zinc are itemised and the other six are not. The chart is what that rule looks like when it is used to its limit.

This is what the label states, exactly:

The second tab is the whole argument of this site in one table: a label can be entirely accurate and still leave a reader unable to answer the only question they came with.

The carnitine ceiling

One ingredient in the blend has a substantial file at the sources this desk reads. It is the second-listed, so its ceiling is the second-highest, and the comparison still does not go the product’s way.

285 mg at most, against the doses the research usedThe L-carnitine ceiling set beside the amounts the NIH records.

Maxorin, L-carnitine ceilingat most 285 mg

The lowest dose studied for performance1,000 mg

The highest dose studied for performance4,000 mg

Where side effects are recordedabout 3,000 mg

100 mg300 mg1 g2 g4 g

The amber bar is not an amount — it is a ceiling. L-carnitine is second in a six-item blend totalling 570 mg, and the FDA requires blend ingredients to be listed in descending order of weight, so it cannot exceed 570 ÷ 2 = 285 mg. The true figure is at or below that and could be far below. The three reference bars are the NIH’s: it records athletic-performance studies using 1 to 4 grams, and notes that around 3 grams a day is where nausea, cramps and a fishy body odour appear. It also says something more fundamental: “Healthy children and adults do not need to consume carnitine from food or supplements because the liver and kidneys synthesize sufficient amounts to meet daily needs.”

Two things follow, and they are separable. The first is the dose: the ceiling is at most a quarter of the lowest studied amount and the real figure could be a fraction of that. The second is more basic and does not depend on the dose at all — the NIH’s position is that healthy people do not need supplemental carnitine, because the liver and kidneys already make enough.

Its verdict on the performance literature is worth having in full as well: “the evidence on supplemental carnitine’s effectiveness for performance enhancement is mixed, and additional investigations are needed”. The ingredients page sets the row out in detail.

The caution block is the fullest in this batch and it was not required to be. It names under-18s, pregnant or nursing mothers, and tells anyone taking a medication or living with a medical condition to consult a physician before use. On a formula whose amounts are 95% undisclosed that instruction is doing more work than usual, because a clinician cannot check what is not printed either.

The distributor block is the weak point: Maxorin, Aurora, CO 80011 is a city, a state and a zip with no street, so there is nothing to post a letter to. The contact page sets out which of the three routes to use for what.

The four marks

Four marks were supplied with this product. Here is what each is a claim about, and who verified it.

60-day money-back guarantee seal — **Money-back**The mark with a real term behind it. The pack publishes a 60-day window from purchase, a returns address and the refund timings.

Good Manufacturing Practice seal — **GMP certified**A process standard for the factory: written procedures, training, cleaning and batch records. Entirely about how the capsules were made rather than what is in them. No certifying body is named, and the mark is not printed on the label artwork itself.

FDA-registered facility roundel — **FDA registered facility**A facility registration is an administrative list. It is not an inspection, not an endorsement, and not approval of the product. No registration number is given. The label carries the standard disclaimer that these statements have not been evaluated by the FDA.

Foreign and domestic ingredients seal — **Foreign and domestic ingredients**An unusually candid mark, and worth crediting: it says plainly that the material is sourced from more than one country. It is not a claim about where the capsules were made, and no country of manufacture is printed on the artwork at all.

A GMP mark, an FDA-registered-facility mark and a foreign-and-domestic-ingredients mark were supplied alongside the product. None of the three is printed on the label artwork itself, and none names a certifying body or carries a registration number. That is worth knowing: a mark that appears in a marketing folder but not on the bottle is a claim made by the seller rather than by the label.

The foreign and domestic ingredients mark is the one this desk would single out, because it is candid in a way marks in this trade usually are not: it says plainly that the material comes from more than one country, where most products either claim domestic origin or say nothing. It is not a statement about where the capsules were made, and no country of manufacture is printed on the artwork at all.
