Seven ingredients carry stated amounts. Five do not. Rather than describing all twelve in the same glowing adjectives, we print the numbers and grade each one against what the research actually covers — including the three we think you should discount.
MemoHoney lists twelve active ingredients per capsule: Bacopa Monnieri, Ginkgo Biloba, blueberry, astaxanthin, honey, niacin (7.5 mg, 47% DV), calcium as calcium carbonate (18 mg, 1.5% DV), L-arginine (200 mg), L-arginine AKG (200 mg), L-citrulline HCl (100 mg), L-citrulline malate (100 mg) and beta-alanine (40 mg). The five botanicals and the carotenoid carry no stated per-capsule amount. The capsule shell is hypromellose.
| Ingredient | Amount | % DV |
|---|---|---|
| Niacin | 7.5 mg | 47% |
| Calcium (as Calcium Carbonate) | 18 mg | 1.5% |
| L-Arginine | 200 mg | † |
| L-Arginine AKG (2:1 extract) | 200 mg | † |
| L-Citrulline HCl | 100 mg | † |
| L-Citrulline Malate | 100 mg | † |
| Beta-Alanine | 40 mg | † |
| Bacopa Monnieri | not stated | † |
| Ginkgo Biloba | not stated | † |
| Blueberry | not stated | † |
| Astaxanthin | not stated | † |
| Honey | not stated | † |
† Daily Value not established.
Other ingredients: Hypromellose (vegetable capsule shell).
Five of the twelve actives carry no stated per-capsule amount. We show that as
“not stated” rather than filling the gap with a guess.
The strongest cognitive citation in the formula. A randomised, double-blind, placebo-controlled trial reported cognitive, mood and anxiety benefits in older adults, and a separate meta-analysis of RCTs supports standardised extracts.
Strong cognitive evidenceA double-blind RCT linked blueberry polyphenols to improved vascular function and cognitive performance in healthy older adults. Genuinely on-topic research — though the label does not state how much blueberry is in each capsule.
Strong cognitive evidenceOne of the most widely studied botanicals for cognitive support. Clinical trials generally use 80–720 mg per day. Known to interact with blood-thinning medication, so clear it with your doctor first.
Supporting evidenceAn essential nutrient with an established role in cellular energy metabolism. This is a real, meaningful dose at 47% of the Daily Value — not a fairy dusting.
Supporting evidenceA nitric-oxide precursor. The research base is solid but sits mostly in cardiovascular and exercise-performance studies rather than memory trials.
Supporting evidenceAn alpha-ketoglutarate form of arginine used to extend nitric-oxide support. Same research caveat: strong in exercise science, thin in cognition.
Supporting evidenceConverts to arginine in the kidneys and tends to raise circulating arginine more reliably than arginine itself. Again: blood-flow research, not memory research.
Supporting evidenceCitrulline bound to malic acid. Popular in sports nutrition; included here to support the same nitric-oxide pathway the brand builds its positioning around.
Supporting evidenceA carotenoid antioxidant from microalgae. The research reviewed centres on antioxidant activity generally rather than cognition specifically.
Supporting evidenceThe ingredient the brand is named after. Published honey research centres on wound care and cough suppression — not memory. Treat it as a formulation and flavour component, not the active driver.
Limited relevance1.5% of the Daily Value. This is a formulation-level amount — useful as an excipient, not a meaningful calcium source. Don't count it toward your daily intake.
Limited relevanceThe formula's biggest gap between marketing and dose. Clinical research on beta-alanine typically uses 4,000–6,000 mg per day — 100 to 150 times what is here.
Limited relevancePublished beta-alanine research uses 4,000 to 6,000 mg daily and measures exercise capacity, not cognition. Forty milligrams is roughly one percent of a studied dose, aimed at a different outcome. It is on the label; it should not be in your decision.
That is 1.5% of the Daily Value. Calcium carbonate at this level functions as a formulation aid, not a nutritional contribution. Do not count it toward your calcium intake and do not weigh it as a benefit.
The brand's namesake. Honey's published research is about wound dressing and cough suppression. There is no meaningful cognitive literature on it. It gives the product its name and probably its palatability — treat it as neither more nor less than that.
Why undisclosed amounts matter. Ginkgo trials generally run 80 to 720 mg per day. Bacopa trials use standardised extracts at specific bacoside percentages. Without a stated milligram figure you cannot tell whether this capsule sits inside those research ranges or far below them. That is not proof the amounts are low — it is proof you cannot check. If dose comparison matters to your decision, email support and ask for the figures in writing before ordering.
| Ingredient | Interacts with | What to do |
|---|---|---|
| Ginkgo Biloba | Blood thinners (e.g. warfarin), antiplatelet drugs | Documented bleeding-risk increase. Clear with your doctor before ordering. |
| Bacopa Monnieri | Antidepressant medication | A possible interaction is noted in the literature. Ask your prescriber. |
| L-Arginine / L-Citrulline | Blood pressure medication, nitrates | Both affect vasodilation. Discuss with a pharmacist if you take either. |
| Niacin | High-dose niacin therapy | 7.5 mg is a nutritional dose, well below therapeutic niacin levels. |
| Honey | Pollen or bee-product allergy | Avoid if you have a known bee-product allergy. |
This table lists interaction considerations documented in the published literature for these ingredient categories. It is not a complete list and it is not medical advice. The finished product's full adverse-effect profile has not been independently established.
Twelve actives: Bacopa Monnieri, Ginkgo Biloba, blueberry, astaxanthin, honey, niacin (7.5 mg / 47% DV), calcium as calcium carbonate (18 mg / 1.5% DV), L-arginine (200 mg), L-arginine AKG 2:1 (200 mg), L-citrulline HCl (100 mg), L-citrulline malate (100 mg) and beta-alanine (40 mg). The capsule shell is hypromellose. Five ingredients carry no stated per-capsule amount.
Bacopa Monnieri, without close competition. It carries both a randomised double-blind placebo-controlled trial reporting cognitive, mood and anxiety benefits in older adults, and a separate meta-analysis of RCTs supporting standardised extracts. Blueberry polyphenols come second with a 2023 double-blind trial in healthy older adults. Everything else in the formula has research behind it, but from adjacent fields rather than cognition.
The label lists individual ingredients rather than hiding them inside a single “proprietary blend” total, which is better practice. However, five of the twelve have no amount printed at all — which produces a similar practical problem for a buyer trying to compare doses against published trials.
The capsule shell is hypromellose, a plant-derived cellulose, so the shell is not gelatin. Honey is listed among the actives, so the product is not vegan. Gluten and dairy status are not stated in the materials we reviewed — if you have coeliac disease or a dairy allergy, email support for written confirmation before ordering rather than assuming.
