The first fully disclosed panel this desk has read — and the first time the arithmetic has been possible.
Each MemoHoney capsule lists seven ingredients, and every one has a printed amount.
L-arginine base 200 mg, L-arginine AKG 2:1 200 mg, L-citrulline HCl 100 mg, L-citrulline malate 100 mg, beta alanine 40 mg, niacin 7.5 mg NE and calcium 18 mg. There is no proprietary blend.
See the whole label on the supplement facts page.
Seven lines, seven figures, and a total we added ourselves because the label is not required to.
| As printed on the panel | Per capsule | % Daily Value | What it is |
|---|---|---|---|
| Niacin | 7.5 mg NE | 47% | Vitamin B3. About half an adult day's requirement, and the only nutrient here at a sensible fraction of its Daily Value |
| Calcium (as Calcium Carbonate) | 18 mg | 1.5% | 1.4% of a day's calcium by our arithmetic. Carbonate is also a common capsule filler |
| L-Arginine (base) | 200 mg | †† | An amino acid the body converts to nitric oxide. Studied at 6 to 30 grams a day |
| L-Arginine AKG 2:1 Extract | 200 mg | †† | Arginine bound to alpha-ketoglutarate. Our sources do not cover this form separately |
| L-Citrulline HCl | 100 mg | †† | A citrulline salt. Citrulline raises arginine in the blood more reliably than arginine does |
| L-Citrulline Malate | 100 mg | †† | 56.64% citrulline by weight, per the NIH. Studied at 8 grams before exercise |
| Beta Alanine | 40 mg | †† | Studied at 1.6 to 6.4 grams a day for four to eight weeks, for muscular endurance |
| Total declared per capsule | 665.5 mg | — | Our addition, from the seven printed figures. The label prints no total and is not required to. |
There is no proprietary blend. Seven dietary ingredients are declared and every one of them carries a figure. Nothing is concealed inside a total weight, nothing is described only as part of a matrix, and no ceiling arithmetic is needed anywhere on this site. Of the products this desk has reviewed, this is the first with a full house.
The footnote†† Daily Value (DV) not established.
Other ingredientsThree, as printed: Hypromellose (Vegetable Capsule), Vegetable Stearate and Silicon Dioxide.
The two percentages, recomputedNiacin: 7.5 mg NE against a 16 mg NE Daily Value is 46.9%, which to the nearest whole percent is 47% — the printed figure is correct. Calcium: 18 mg against a 1,300 mg Daily Value is 1.4%, which to the nearest whole percent is 1%. The panel prints 1.5%.
This is the sentence this desk has been waiting to write, so it is going at the top of the ingredients page rather than being buried.
On a proprietary blend, a label declares one total weight for a list of ingredients and prints no individual figures. 21 CFR 101.36(c) permits it, and the only thing a reader can still do is derive a ceiling from the descending-order rule — an upper bound, never a floor, and never an actual amount.
None of that machinery is needed here. Every dietary ingredient in this product has a number printed beside it. No ceilings were computed anywhere on this site. No figure on this page is an estimate. Everything below is either read off the bottle or arithmetic performed on figures read off the bottle, and we say which is which.
The FDA's labeling guide states the requirement in a sentence: “You must list the names and quantities of dietary ingredients present in your product, the ‘Serving Size’ and the ‘Servings Per Container.’” This panel does all three for all seven.
Which brings us to the uncomfortable part, and it is uncomfortable precisely because of the disclosure: once you can see the amounts, you can compare them.
Not to flatter a product. To let a buyer check it. This label passes the first test that every other product on this desk has failed, and the checking is what the rest of this page does.
Sourced, one at a time, including the parts that do not flatter the product.
Every dietary ingredient on this panel carries a figure. There is no proprietary blend and nothing hidden inside a total. That single fact is what makes every other number on this site possible, and it is the strongest thing about this product.
Niacin 7.5 mg, calcium 18 mg, arginine 200 mg, arginine AKG 200 mg, citrulline HCl 100 mg, citrulline malate 100 mg, beta-alanine 40 mg. The label does not print a total; we added the seven lines it does print.
The NIH records a protocol using 8 grams of citrulline malate. This capsule holds 100 milligrams of it. Eighty capsules is two and two thirds bottles, taken in a day.
The NIH records 1.6 to 6.4 grams a day over four to eight weeks. This capsule holds 40 milligrams. At the top of that range it would be a hundred and sixty capsules.
The product scene is staged with four recognised brain-health botanicals. None of them is on the panel and the brand claims none of them in writing. NCCIH says there is no conclusive evidence that ginkgo prevents or slows cognitive decline.
Seven dietary ingredients and three other ingredients, and honey is not among the ten. The name, the honeycomb logo and the dripping-honey artwork all point at something the bottle does not contain.
See the full Supplement Facts panel for every line on the label.
The label says one a day. Each row draws the number you would actually have to swallow — arithmetic that is only possible because every figure is printed.
2 capsules to reach 16 mg a daySource: NIH: the RDA for adult men is 16 mg NE
The one row on this page that is not absurd, and we want to say so plainly. Two capsules would cover an adult man's daily niacin, and one covers about half of it. Most people already get niacin from food — the NIH puts the adult Tolerable Upper Intake Level for supplemental niacin at 35 mg, and says flushing typically begins at 30 to 50 mg — so 7.5 mg is a modest, sensible top-up rather than a pharmacological dose. It is also the only ingredient in this bottle you could describe that way.
15 capsules to reach 6 g a daySource: Drugs.com: current daily dosage trends range from 6 to 30 g
The capsule carries 200 mg of L-arginine base plus 200 mg of L-arginine AKG 2:1 extract. Counting every milligram of both as arginine — which is generous, because the AKG fraction is not arginine — the capsule holds 400 mg.
The monograph we read puts current daily dosage trends at 6 to 30 grams, in three divided doses. Fifteen capsules is the bottom of that. And the NIH's own view of arginine is bleaker still: doses of 2 to 20 g a day have “little to no effect on performance,” and little to no effect on nitric oxide concentration or blood flow either.
40 capsules to reach 1.6 g a daySource: NIH: studies used 1.6–6.4 g/day over 4–8 weeks
Forty capsules is the bottom of the studied range. The top of it, 6.4 grams, would be a hundred and sixty.
There is a silver lining and it is worth stating: the NIH records that beta-alanine causes moderate to severe paresthesia — tingling, prickling or burning lasting 60 to 90 minutes — at doses of at least 800 mg. At 40 mg you will feel nothing at all, which is both a genuine comfort and the clearest possible sign of where this amount sits.
72 capsules to reach 1,300 mg a daySource: FDA: the Daily Value for calcium is 1,300 mg
Seventy-two capsules for one day's calcium. This is not a criticism of the formulation — nobody buys a memory supplement for its calcium — but it is the reason the printed 1.5% matters: the honest figure is 1.4%, and a nutrient under 2% of its Daily Value is at the level the regulations let a label describe as negligible.
Calcium carbonate is also one of the most common capsule fillers there is. We are not claiming that is what it is doing here; we are noting that 18 mg is not a calcium supplement by any definition.
80 capsules to reach 8 g a daySource: NIH: one protocol used 8 g citrulline malate before exercise
Eighty capsules. Eighty.
The NIH also gives the conversion: citrulline malate is 56.64% citrulline by weight, so the 100 mg in this capsule is about 57 mg of citrulline. The capsule carries a further 100 mg of L-citrulline HCl, and none of the sources we opened gives a conversion for the HCl salt, so this site does not invent one.
This is the row that decides the product. Citrulline is the ingredient in this formula with the best claim to doing something, and the bottle holds roughly one eightieth of a studied dose per capsule.
Five rows, each on its own linear scale. Every bar is a real printed number against a real published dose.
One capsule, as printedA dose that makes senseWhat the research usedmilligrams, one linear scale per row
Every bar on this chart is a real printed number against a real published dose. There are no ceilings here, no blanks and no estimates, because this label declares an amount for every ingredient in the product. That is what full disclosure buys a reader: not a flattering picture, but a checkable one. Four of the five bars are slivers, and you can see that they are slivers only because the brand printed the figures.
Citrulline has the best claim to doing something here, and it is the furthest from a studied amount.
Citrulline is converted in the body to arginine, and it raises blood arginine more reliably than arginine taken directly does. That is a real and well-described pathway, and it is the strongest mechanism story this formula has.
The NIH's fact sheet records a protocol using 8 grams of citrulline malate before exercise. This capsule holds 100 milligrams of it. That is one eightieth, and the label's instruction is one capsule a day.
The same source gives the conversion, which is worth having: citrulline malate is 56.64% citrulline by weight. So the 100 mg on this panel is about 57 mg of citrulline.
There is a second citrulline line, 100 mg of L-citrulline HCl, and this is where we stop. None of the sources we opened gives the citrulline fraction of the hydrochloride salt, so this site publishes no conversion for it. We could look one up on a supplier's datasheet; we do not cite supplier datasheets, for the same reason we do not cite a logo.
What can be said without any conversion at all: the two citrulline lines together are 200 milligrams of salt, and the studied dose is measured in grams.
Because if any ingredient here were going to do something for cerebral blood flow, citrulline is the one — and it is the one furthest below its own literature.
This panel prints a percent Daily Value for two of its seven ingredients. We checked both against the FDA's published figures, and they do not both survive.
| Nutrient | Declared | % DV printed | Daily Value | Our figure | Verdict |
|---|---|---|---|---|---|
| Niacin | 7.5 mg NE | 47% | 16 mg NE | 46.9%, which to the nearest whole percent is 47% | correct |
| Calcium | 18 mg | 1.5% | 1,300 mg | 1.4%, which to the nearest whole percent is 1% | the printed figure is neither the correct value nor a whole percent |
A percentage on a panel is the one number a reader can check without leaving the label, and almost nobody does. We recompute every one we find. On this product there were two to check: one is right and one is not.
What the rule saysThe FDA’s dietary supplement labeling guide requires percentages to be expressed “to the nearest whole percent”. 1.5% is not a whole percent, and 1.4% rounds to 1% rather than to 1.5% in any case.
How much it mattersVery little, on its own. Eighteen milligrams of calcium is negligible either way and nobody’s decision turns on it. It matters as a signal: this is the only figure on an otherwise careful panel that does not survive a recalculation, and we would rather report it than quietly let it pass.
Every figure in the second column is printed on the bottle. Every figure in the third is from a named source we opened.
| Ingredient, in panel order | Per capsule | What our sources record | Capsules to reach it |
|---|---|---|---|
| Niacin | 7.5 mg NE | 16 mg NE a day, the adult RDA for men; UL 35 mg for supplemental niacin | 2 |
| Calcium (as calcium carbonate) | 18 mg | 1,300 mg a day, the FDA Daily Value | 72 |
| L-Arginine (base) | 200 mg | 6–30 g a day in three divided doses | 30, on the base alone |
| L-Arginine AKG 2:1 Extract | 200 mg | not covered separately in any source we opened | — |
| L-Arginine, both forms counted | 400 mg | 6 g, the bottom of the range | 15 |
| L-Citrulline HCl | 100 mg | no conversion for this salt in our sources | — |
| L-Citrulline Malate | 100 mg | 8 g before exercise; 56.64% citrulline by weight | 80 |
| Beta Alanine | 40 mg | 1.6–6.4 g a day over 4–8 weeks | 40 at the bottom, 160 at the top |

Three images from the supplied set. None of these is an ingredient in the product and the brand does not claim they are.
The context is worth having. Dietary protein supplies several grams of arginine a day to most people who eat normally, which is the scale the monograph's 6 to 30 gram figure lives at. This capsule adds 400 milligrams to that.
MemoHoney is a memory supplement in 30-capsule bottles, one capsule a day. Its panel declares seven ingredients and prints an amount for every one of them — and that disclosure is what lets anyone see how far below the studied doses those amounts sit. We publish the arithmetic rather than the adjectives.

Other ingredients: hypromellose vegetable capsule, vegetable stearate and silicon dioxide. The seven declared amounts come to 665.5 mg, which is our addition rather than the label's.
No, and it is the best thing about this label. Every dietary ingredient carries a printed amount. Nothing is concealed inside a total weight, nothing is described only as part of a matrix, and the panel can be added up by anyone with a calculator. Of the products this desk has reviewed, this is the first with a full house.
We added the seven printed figures: 7.5 + 18 + 200 + 200 + 100 + 100 + 40. The label does not print a total and is not required to. We publish ours as ours.
Arginine is an amino acid the body converts to nitric oxide, which relaxes blood vessels. That is a real mechanism. The question is the amount: the monograph we read puts current daily dosage trends at 6 to 30 grams a day in three divided doses, and this capsule holds 400 mg counting both arginine forms.
Fifteen capsules a day to reach 6 grams, which is the bottom of the range in the monograph we read. The label says one. The NIH is less encouraging still: it reports that 2 to 20 grams a day of arginine has little to no effect on performance, and little to no effect on nitric oxide concentration or blood flow.
Arginine bound to alpha-ketoglutarate in a stated two-to-one ratio. None of the sources we opened covers this form separately — the NIH's exercise fact sheet mentions alpha-ketoglutarate once, in the creatine section — so this site does not convert the 200 mg into an arginine figure and does not claim the form has evidence of its own.
Citrulline is converted in the body to arginine, and it raises blood arginine more reliably than arginine taken directly. It feeds the same nitric oxide pathway. The capsule holds two citrulline salts, 100 mg of the HCl and 100 mg of the malate.
Eighty capsules to reach the 8 gram citrulline malate protocol the NIH records. The label says one a day, so that is two and two-thirds bottles in a single day. It is the starkest comparison on the site.
About 57 mg from the malate. The NIH gives the conversion: citrulline malate is 56.64% citrulline by weight, so 100 mg of malate is 56.6 mg of citrulline. None of our sources gives a conversion for the hydrochloride salt, so we publish no figure for the other 100 mg.
We do not know and the material does not say. It is an unusual choice on a panel with only seven lines. What we can say is that together they come to 200 mg of salt against a studied dose measured in grams.
That is a fair question. Beta-alanine is studied for muscular endurance and it appears in the NIH's fact sheet on exercise and athletic performance, not in NCCIH's digest on cognition. The studied range is 1.6 to 6.4 grams a day over four to eight weeks; this capsule holds 40 mg.
No. The NIH records that paresthesia — tingling, prickling or burning lasting 60 to 90 minutes — occurs at doses of at least 800 mg. At 40 mg you will feel nothing. That is a genuine comfort and also the clearest available sign of where this amount sits.
Yes, and it is the one ingredient here we would describe that way. 7.5 mg NE is about half the adult RDA, which the NIH gives as 16 mg NE for men and 14 for women. It is well under the 35 mg Tolerable Upper Intake Level for supplemental niacin, and far below the 30 to 50 mg at which flushing typically starts.
The material does not say. Eighteen milligrams is 1.4% of the FDA's 1,300 mg Daily Value, which is not a calcium supplement by any definition. Calcium carbonate is also among the most common capsule fillers there is; we are not claiming that is what it is doing here, only that the amount is negligible as nutrition.
