HelloPharmacist Scorecard of NeuPerzine by Biotics Research Corporation

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 27, 2026

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 1 of its 1 active ingredient.
  • “Huperzia serrata” is listed as a grouped ingredient — the label gives one combined amount (10 mg) without saying how much of each component you get.

NeuPerzine contains one active ingredient: huperzine A, a compound extracted from club moss that works by slowing the breakdown of acetylcholine, a brain chemical involved in memory and thinking. The capsule also contains microcrystalline cellulose (a filler), magnesium stearate, and the capsule shell itself — all inactive ingredients.

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: Memory and cognitive support.
  • We looked for evidence on: Alzheimer disease, Cognitive impairment, Memory, Vascular dementia, Age-related cognitive decline, Dementia — and 1 related terms.
  • The strongest evidence on file: Huperzine A is rated "Possibly Effective" for Alzheimer disease (Natural Medicines).
  • Also on file: Huperzine A is rated "Insufficient Reliable Evidence To Rate" for Cognitive impairment, Vascular dementia, Memory.

Huperzine A is possibly effective for Alzheimer disease based on available evidence. For athletic performance, cognitive impairment, vascular dementia, depression, and memory, the evidence we hold is insufficient to rate how well it works.

If you're considering this product for one of those other uses, there isn't enough reliable data yet to know whether it'll help.

The evidence, ingredient by ingredient Toothed Clubmoss Huperzine A

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Taken by mouth, huperzine A is generally well tolerated, though it can cause dose-dependent cholinergic side effects — blurred vision, constipation, diarrhea, dizziness, dry mouth, insomnia, nausea, sweating, vomiting, decreased heart rate, and loss of appetite. High doses or accidental overdose from plant sources have caused serious toxicity.

The safety data advises against use during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Huperzine A.
  • The most serious interaction on file is rated Moderate.
  • For scale: 219 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking NeuPerzine, double-check any cholinergic drugs (medications that boost acetylcholine) and anticholinergic drugs (medications that block acetylcholine) you're on. Both types can interact at a Moderate level with huperzine A.

Your pharmacist can search your prescriptions using the tool on this page.

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).

NeuPerzine by Biotics Research Corporation: Common Questions

Does NeuPerzine by Biotics Research Corporation interact with any medications?
Yes. Based on its ingredients, NeuPerzine has a known interaction with 219 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
NeuPerzine contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is huperzine A?
Huperzine A is a compound from club moss that blocks an enzyme in your brain, slowing the breakdown of acetylcholine — a chemical important for memory and thinking. It's used in supplements intended to support brain function.
Can I take NeuPerzine if I'm pregnant or breastfeeding?
No. The safety data advises against huperzine A during pregnancy and while breastfeeding because there isn't enough information to know it's safe in those situations. Talk with your doctor or pharmacist about whether this product is right for you.
What side effects might I experience?
Huperzine A can cause dose-dependent cholinergic side effects like blurred vision, constipation, diarrhea, dizziness, dry mouth, insomnia, nausea, sweating, vomiting, and decreased heart rate. High doses carry a risk of serious toxicity.
Does it work for memory problems?
The evidence we have isn't strong enough to say huperzine A works for general memory issues. It's possibly effective for Alzheimer disease, but for other memory or cognitive concerns, the data is insufficient to rate it.
Is this supplement safe to take long-term?
Huperzine A is a pharmacologically active compound, meaning it can cause real side effects. Use it only with care and medical guidance. Your doctor or pharmacist can help you weigh the benefits and risks for your situation.
