I've reviewed dozens of nootropic supplements for HathawayMD. Most of them share the same failure mode: a formula built from ingredients that have real research behind them individually, assembled into a blend where the dosages are hidden, and marketed with claims that stretch well past what any of the actual studies support.
Memopryl fits that description in some ways and doesn't in others. The eight-ingredient formula is genuinely drawn from the more credible end of the nootropic research literature. The interaction risk profile — which no other review I've found treats with any real specificity — is the thing I want to address directly before anything else.
If you take prescription medication, read the interaction section of this review before you read anything else. St. John's Wort is in this formula. The combination of three cholinergic-pathway ingredients in one bottle is also something anyone on a prescription Alzheimer's medication needs to know about. This isn't scare language. It's the information the product's own marketing doesn't surface clearly.
Here's the full picture.
What Is Memopryl?
Memopryl is a nootropic dietary supplement manufactured by MemoPryl Research and sold exclusively through the official website at memopryl.com, with payments processed through ClickBank. It is not available on Amazon, eBay, or through any third-party retail channel — the company's stated reason is quality control.
The formula contains eight ingredients: Ginkgo Biloba, Phosphatidylserine, Bacopa Monnieri, Alpha-GPC, N-Acetyl-L-Carnitine, Huperzine-A, St. John's Wort, and L-Glutamine. The product is manufactured in the United States in an FDA-registered, GMP-certified facility. Individual ingredient dosages are not publicly disclosed — the formula operates as a proprietary blend.
The serving size is two capsules daily, taken with breakfast. The brand recommends consistent daily use for a minimum of 90 days before evaluating results, citing the research timelines for slow-acting ingredients like Bacopa Monnieri.
Memopryl is a dietary supplement, not a pharmaceutical drug. It has not been FDA-approved. It is not intended to diagnose, treat, cure, or prevent any disease. There are no published randomized controlled trials on the finished Memopryl formula. These are facts, not criticisms — they apply to every nootropic supplement on the market.
The Eight Ingredients: What the Research Actually Shows
Because individual ingredient dosages are not disclosed, this analysis draws on the published research for each compound in the contexts typically studied. This is ingredient-level research context, not product-level efficacy claims.
Ginkgo Biloba is among the most studied botanical compounds in cognitive wellness research. The mechanism most commonly cited involves cerebrovascular effects — improved blood flow to brain tissue — along with antioxidant activity. A 2014 Cochrane review of Ginkgo Biloba across 36 trials found some evidence supporting its use in age-related cognitive decline, with effect sizes that were modest and inconsistent across populations. Effective doses in most studies ranged from 120 mg to 240 mg daily. Because Memopryl's dosages are undisclosed, whether the formula reaches these thresholds is unknown.
Phosphatidylserine is a phospholipid that forms part of the structure of neuronal cell membranes. The FDA has authorized a qualified health claim (not a drug approval) for phosphatidylserine and cognitive decline — specifically for its potential to reduce the risk of dementia in older adults, with the caveat that evidence is limited and not conclusive. Studies evaluating phosphatidylserine for memory and cognitive function in aging adults have used doses typically ranging from 100 mg to 300 mg daily.
Bacopa Monnieri is an Ayurvedic herb with the strongest evidence base of any ingredient in this formula for the specific outcome of memory consolidation. Multiple randomized controlled trials have found statistically significant improvements in delayed word recall, visual processing speed, and working memory in adults. The critical variable: most studies showing meaningful effects used 300 mg to 450 mg daily over 12 weeks or longer. Bacopa is a slow-acting compound. Users who evaluate it at four weeks are not giving it the time the research protocols used.
Alpha-GPC (Alpha-glycerylphosphorylcholine) is a choline compound that crosses the blood-brain barrier efficiently and serves as a direct precursor to acetylcholine, the neurotransmitter most directly associated with learning and memory encoding. Research in older adults with mild cognitive decline has used doses of 400 mg three times daily. This is a potent cholinergic precursor — and its combination with two other cholinergic-pathway ingredients in this formula is worth noting explicitly (see the Safety section of this review).
N-Acetyl-L-Carnitine (ALCAR) is an acetylated form of L-carnitine that enters the brain and supports mitochondrial energy production in neurons. Research has explored its role in slowing age-related cognitive decline, with some trials showing modest improvements in memory and attention in older adults. ALCAR also has a mild cholinergic effect — it supports acetylcholine synthesis — which is the third cholinergic-pathway ingredient in this formula.
Huperzine-A is derived from club moss and works by inhibiting acetylcholinesterase, the enzyme that breaks down acetylcholine. By slowing acetylcholine breakdown, it effectively raises acetylcholine levels in the brain. Huperzine-A is one of the few botanical nootropic ingredients that operates through a mechanism nearly identical to a class of FDA-approved prescription drugs (cholinesterase inhibitors like donepezil). This is not a safety concern for healthy adults without prescription cognitive medications — but it is the central issue in the drug interaction profile discussed below.
St. John's Wort is included in many cognitive support and mood formulas for its association with serotonin and dopamine pathway support. The research on St. John's Wort for mood is reasonably well-established in mild-to-moderate applications. The drug interaction profile is the reason this ingredient is flagged prominently in this review — and in the separate safety article in this series.
L-Glutamine is an amino acid involved in neurotransmitter synthesis and serves as a precursor to both glutamate and GABA. It contributes to brain energy metabolism as a secondary fuel source. Research on L-Glutamine specifically in cognitive supplement contexts is less robust than the other ingredients in this formula, but it is generally well-tolerated and its inclusion is mechanistically consistent with overall neurological support.

The Interaction Risk You Need to Know Before Buying
This is the section that matters most for a specific subset of readers.
St. John's Wort and prescription medications. St. John's Wort is a potent inducer of cytochrome P450 enzymes and P-glycoprotein — the liver and intestinal systems responsible for metabolizing a large percentage of prescription drugs. This means it can reduce the blood concentration of drugs it interacts with, potentially rendering them less effective or altering their dosing requirements. Documented interactions include SSRIs and SNRIs (serotonin syndrome risk when combined), warfarin (reduced anticoagulant effect), oral contraceptives (reduced efficacy), certain antiretrovirals, cyclosporine, and digoxin. If you take any prescription medication, the standard clinical guidance is to discuss St. John's Wort use with your prescribing physician before starting it.
The cholinergic stack and prescription Alzheimer's medications. Memopryl contains three ingredients — Alpha-GPC, N-Acetyl-L-Carnitine, and Huperzine-A — that all act on the cholinergic system simultaneously. For healthy adults not on prescription medication, this is a design feature rather than a problem. For adults taking donepezil (Aricept), rivastigmine (Exelon), galantamine (Razadyne), or memantine (Namenda), the combination with a triple-cholinergic supplement stack requires a physician conversation first. This is not a warning against using Memopryl — it is information the product's marketing doesn't make explicit and that most reviews online don't flag at all.

What Memopryl Does Not Claim — and Why That Matters
Some Memopryl advertising circulating on social media in 2026 has featured fake celebrity endorsements, claims about reversing Alzheimer's disease, and a “secret honey recipe” angle. This review is not evaluating the advertising funnel — it is evaluating the product. The supplement itself is a straightforward nootropic formula with disclosed ingredients, a US manufacturer, and a legitimate return policy. The marketing tactics used in some advertising placements are a separate issue from what is in the bottle.
The official Memopryl product page makes no Alzheimer's reversal claims, no celebrity endorsement claims, and no disease treatment claims. It carries the standard DSHEA disclaimer that statements have not been evaluated by the FDA and the product is not intended to diagnose, treat, cure, or prevent any disease. That is what any legitimate dietary supplement should say.
Pricing and Packages (Verified May 2026)
Memopryl is available in three purchase tiers through the official website. All prices are subject to change — verify current pricing at memopryl.com before ordering.
2-bottle package: $79 per bottle, $158 total, plus $9.99 shipping. This is the 60-day supply.
3-bottle package: $69 per bottle, $207 total, free shipping. This is the 90-day supply and the minimum timeframe most of the research protocols for slow-acting ingredients like Bacopa Monnieri actually used.
6-bottle package: $49 per bottle, $294 total, free shipping. This is the 180-day supply and the lowest per-bottle cost.
The 3-bottle package is the practical minimum for anyone who wants to give the formula a genuine evaluation window aligned with how the ingredient research was conducted.
The Refund Policy — Exact Terms
Memopryl carries a 60-day money-back guarantee from the date of shipment — not the date of purchase. The terms that most competing reviews don't state clearly: you must return all bottles to qualify for a full refund. This includes any bottles that have been opened or are empty. Buyers cover return shipping costs. Contact [email protected] before returning — the company requires an email confirmation before a return is processed. The return address is 19655 E 35th Drive, Suite 100, Aurora, CO 80011. Refund processing takes approximately 5 to 10 business days once the return is received.
This is a legitimate refund policy. The “return all bottles” requirement is standard in the supplement industry and does not represent hidden fine print — it simply isn't stated prominently enough in most reviews for buyers to plan accordingly.
What to Expect Realistically
The marketing language around Memopryl uses terms like “sharpened memory,” “sustained concentration,” and “elevated cognitive clarity.” These are the intended goals of the formula — not clinically validated outcomes from trials on the Memopryl blend itself. The research context for this category is clear: ingredients like Bacopa Monnieri and Phosphatidylserine show modest but real effects in certain populations, primarily older adults, at specific doses, over meaningful evaluation periods. L-Glutamine and Ginkgo Biloba have more variable effect profiles. Alpha-GPC and Huperzine-A have clearer mechanistic rationale for short-term cholinergic support.
What this means practically: if you start Memopryl expecting dramatic cognitive improvement within two weeks, you'll likely be disappointed. If you start it expecting incremental support over three to four months, you're in the right frame of reference for how this category of supplement works.

Lena Hathaway's Assessment
Memopryl is a credibly assembled nootropic formula. The eight ingredients have legitimate research contexts, the manufacturing credentials are verifiable, and the refund policy is real. The primary limitation — shared by essentially every supplement in this category — is the absence of dosage transparency and the absence of a clinical trial on the finished product.
The St. John's Wort interaction profile and the triple cholinergic stack are the two things any physician would flag in a clinical intake. They are not disqualifying for most healthy adults. They are exactly the kind of specific, actionable information that's missing from every other Memopryl review I found in researching this piece.
Compared to simpler formulations in this category — such as the MemoryFuel supplement, which uses a different ingredient approach focused on brain energy and choline precursors without the St. John's Wort variable — Memopryl carries more interaction risk for adults on prescription medications. For healthy adults not on prescription medication, the formula is a reasonable option within the nootropic supplement category.
If you're considering Memopryl and currently take any prescription drug, that conversation happens with your prescribing physician first. Not because this supplement is unusually dangerous, but because the St. John's Wort interaction profile is well-documented enough to warrant the conversation.
