HelloPharmacist Scorecard of Brain/Memory with Huperzine A by Vinco

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 5 of its 5 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Vinco's Brain/Memory formula contains 5 active ingredients: Vinpocetine, N-Acetyl-L-Carnitine Hydrochloride, Phosphatidyl Complex, Huperzia serrata Extract, and Bacopa monnieri Extract. Vinpocetine is a compound derived from the periwinkle plant thought to improve blood flow to the brain.

N-Acetyl-L-Carnitine (often called ALCAR) is an amino acid form of carnitine involved in energy production in brain cells. Huperzia serrata extract and Bacopa monnieri are plant-based ingredients traditionally used in memory and cognitive support formulas.

The product also contains inactive ingredients — gelatin capsule, rice flour, vegetable stearate, and silicon dioxide — to hold and deliver the formula.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: healthy cognition and memory recall.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Cognitive function, Cognitive impairment, Dementia, Memory — and 4 related terms.
  • The strongest evidence on file: Vinpocetine is rated "Possibly Effective" for Dementia (Natural Medicines).
  • Also on file: Acetyl-l-carnitine is rated "Possibly Effective" for Age-related cognitive decline, Alzheimer disease.
  • Also on file: Vinpocetine is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline, Memory.

The evidence for this product's ingredients is mixed. Vinpocetine is rated possibly effective for dementia, but the data for tinnitus, motion sickness, stroke, and chronic fatigue syndrome is insufficient to rate.

N-Acetyl-L-Carnitine shows possibly effective evidence for age-related cognitive decline, Alzheimer disease, alcohol use disorder, diabetic neuropathy, and depression. Bacopa monnieri has insufficient reliable evidence for Alzheimer disease, sexual dysfunction, ADHD, back pain, cognitive function, and cognitive impairment in our data.

Overall, the strongest evidence exists for a couple of the ingredients in specific conditions, but much of the formula's claimed benefit rests on ingredients we simply don't have solid trial data for.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vinpocetine is generally well tolerated short-term, though long-term safety isn't firmly established. Most common side effects include anxiety, dizziness, headache, flushing, stomach discomfort, and sleep issues.

Rare serious side effects (like arrhythmias and seizures) have been reported. The FDA has specifically warned that people who are or could become pregnant should not use vinpocetine, and it's best avoided while breastfeeding due to insufficient safety data.

N-Acetyl-L-Carnitine is also generally well tolerated short-term. Common side effects are agitation, dry mouth, headache, insomnia, and reduced appetite; a metabolite can cause a fishy odor in urine, breath, and sweat.

It's best avoided in pregnancy and while breastfeeding unless your doctor advises otherwise. Bacopa is generally well tolerated in studies, with common side effects including abdominal cramps, diarrhea, dry mouth, headache, nausea, drowsiness, and vivid dreams.

Gastrointestinal issues occurred in 12–30% of trial participants. Bacopa should be avoided during pregnancy and while breastfeeding due to insufficient safety information.

Bacopa monnieri Extract8 drug types · 930 drugs

Anticholinergic Drugs

Theoretically, concurrent use might decrease the effectiveness of both agents.
Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels, which could counteract the effects of anticholinergic drugs. Similarly, anticholinergic drugs might counteract the cholinergic effects of bacopa.

Likelihood Possible Evidence D
Cevimeline (Evoxac)

Theoretically, bacopa might increase the effects and adverse effects of cevimeline.
In one case, a 58-year-old female taking cevimeline long-term for Sjogren syndrome experienced hyperhidrosis, malaise, nausea, and tachycardia shortly after taking a single dose of bacopa. Symptoms resolved after two days. Cevimeline is metabolized by cytochrome P450 (CYP) 2D6 and CYP3A4, and researchers theorize that bacopa may have inhibited these isoenzymes. However, it is unclear if bacopa causes clinically significant inhibition of either CYP2D6 or CYP3A4.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, concurrent use of bacopa with other cholinergic drugs might have additive effects.
Bacopa seems to inhibit acetylcholinesterase and might increase acetylcholine levels. Theoretically, this could result in additive cholinergic effects when used with cholinergic drugs.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, bacopa might increase the levels and adverse effects of CYP1A2 substrates.
Research on the effects of bacopa extracts on CYP1A2 enzymes is conflicting. Some in vitro evidence shows that bacopa extract can moderately and non-competitively inhibit CYP1A2, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, bacopa might increase the levels and adverse effects of CYP2C19 substrates.
In vitro evidence suggests that bacopa extract can moderately and non-competitively inhibit CYP2C19 enzymes. It is not known whether this is clinically significant.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, bacopa might increase the levels and adverse effects of CYP2C9 substrates.
Research on the effect of bacopa extracts on CYP2C9 enzymes is conflicting. Some in vitro evidence suggests that bacopa extract can moderately and non-competitively inhibit CYP2C9, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, bacopa might increase the levels and adverse effects of CYP3A4 substrates.
Research on the effects of bacopa extracts on CYP3A4 enzymes is conflicting. Some in vitro evidence suggests that bacopa extract can moderately and competitively inhibit CYP3A4, while other in vitro evidence suggests that any effect is unlikely to be clinically significant.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, bacopa might have additive effects when used with thyroid hormone.
Animal research suggests that bacopa increases thyroxine (T4) levels in mice by about 40%.

Likelihood Possible Evidence D

Huperzia serrata Extract2 drug types · 219 drugs

Anticholinergic Drugs

In animal models, toothed clubmoss and huperzine A, an active constituent of toothed clubmoss, reversed cognitive deficits induced by scopolamine. Theoretically, concurrent use of anticholinergic drugs and toothed clubmoss might decrease the effectiveness of toothed clubmoss or the anticholinergic drug.
Some anticholinergic drugs include atropine, benztropine (Cogentin), biperiden (Akineton), procyclidine (Kemadrin), and trihexyphenidyl (Artane).

Likelihood Possible Evidence D
Cholinergic Drugs

Huperzine A, a constituent of toothed clubmoss, has demonstrated acetylcholinesterase inhibitory properties. Theoretically, concurrent use of toothed clubmoss with cholinergic drugs might have additive effects and increase the risk of cholinergic side effects.
Cholinergic drugs include bethanechol (Urecholine), donepezil (Aricept), echothiophate (Phospholine Iodide), edrophonium (Enlon, Reversol, Tensilon), neostigmine (Prostigmin), physostigmine (Antilirium), pyridostigmine (Mestinon, Regonol), succinylcholine (Anectine, Quelicin), and tacrine (Cognex).

Likelihood Possible Evidence D

Vinpocetine3 drug types · 208 drugs

Anticoagulant/Antiplatelet Drugs

Vinpocetine might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Clinical research shows that vinpocetine decreases red blood cell aggregation, as well as plasma and whole blood viscosity. This effect has been seen with intravenous vinpocetine 1 mg/kg and oral vinpocetine 30 mg daily. Vinpocetine also seems to have antiplatelet effects.

Likelihood Possible Evidence B
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, vinpocetine might increase levels of drugs metabolized by CYP2C9.
In vitro research shows that vinpocetine weakly inhibits CYP2C9. However, this effect has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Vinpocetine might modestly increase the risk of bleeding when taken with warfarin.
Clinical research shows that the combination of warfarin and vinpocetine leads to slight increases in prothrombin time and the area under the concentration curve for warfarin. However, these increases were small, and researchers suggest that this interaction is not likely to be clinically significant in most patients.

Likelihood Possible Evidence B

N-Acetyl-L-Carnitine Hydrochloride4 drug types · 203 drugs

Acenocoumarol (Sintrom)

Theoretically, acetyl-L-carnitine might increase the anticoagulant effects of acenocoumarol.
L-carnitine, the parent compound of acetyl-L-carnitine, might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant that is similar to warfarin, but shorter-acting. There are at least two case reports of INR elevation when L-carnitine was taken with acenocoumarol. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product. It is unclear if such an interaction would also occur with acetyl-L-carnitine.

Likelihood Possible Evidence D
Serotonergic Drugs

Theoretically, acetyl-L-carnitine might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders, when taken with serotonergic drugs.
Animal research shows that acetyl-L-carnitine can increase levels of serotonin in the brain.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, acetyl-L-carnitine might decrease the effectiveness of thyroid hormone replacement.
L-carnitine appears to act as a peripheral thyroid hormone antagonist by inhibiting entry of thyroid hormone into the nucleus of cells. Taking L-carnitine also seems to diminish some of the symptoms of hyperthyroidism. It is unclear if such an interaction would occur with acetyl-L-carnitine.

Likelihood Probable Evidence B
Warfarin (Coumadin)

Theoretically, acetyl-L-carnitine might increase the anticoagulant effects of warfarin.
L-carnitine, the parent compound of acetyl-L-carnitine, might increase the anticoagulant effects of acenocoumarol, a shorter-acting oral anticoagulant similar to warfarin. There is not enough information to know whether this interaction occurs with acetyl-L-carnitine and warfarin.

Brain/Memory with Huperzine A by Vinco: Common Questions

Does Brain/Memory with Huperzine A by Vinco interact with any medications?
Yes. Based on its ingredients, Brain/Memory with Huperzine A has a known interaction with 1,052 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Brain/Memory with Huperzine A contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant or trying to get pregnant?
No — the FDA has warned that people who are or could become pregnant should not use vinpocetine, one of the key ingredients. The other ingredients also lack sufficient safety data in pregnancy. Talk with your doctor or pharmacist about alternatives if you're pregnant, planning pregnancy, or breastfeeding.
What are the most common side effects?
The most common side effects across the ingredients include headache, dizziness, anxiety, diarrhea, dry mouth, nausea, insomnia, and stomach discomfort. A few people report vivid dreams or a fishy odor in sweat and breath. Most people tolerate the formula short-term without serious problems, but long-term safety data is limited.
Does this really work for memory?
Two of the main ingredients — vinpocetine and N-Acetyl-L-Carnitine — have possibly effective evidence for certain memory and cognitive conditions. Bacopa monnieri, the third active ingredient, doesn't have enough reliable evidence to rate for cognitive function in our data. So the product is only as strong as its most-proven ingredient.
What is Huperzia serrata, and does it interact with medications?
Huperzia serrata is a plant extract included in the formula, but we don't hold interaction data for it — we haven't checked it against medications. If you have questions about this specific ingredient and your drugs, ask your pharmacist.
Why does this product interact with so many medications?
Two of the active ingredients — bacopa and vinpocetine — are processed through your liver's enzyme systems that also break down hundreds of common drugs. When a supplement affects those enzymes, it can theoretically change how your body handles other medications. That's why checking your exact medications is so important.
Is it safe to take this with warfarin or other blood thinners?
No without talking to your doctor or pharmacist first. Both vinpocetine and N-Acetyl-L-Carnitine may increase bleeding risk or boost the effect of blood thinners like warfarin — a Moderate concern. Your provider needs to know you're taking this before starting.
