HelloPharmacist Scorecard of Avipaxin by NS NeuroScience

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

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1.82 Gram(s)) without saying how much of each component you get.

Avipaxin contains three active ingredients in a proprietary blend. Acetyl-L-carnitine HCl is an amino acid compound thought to support brain energy and neurotransmitter function.

Alpha-glycerylphosphorylcholine (alpha-GPC) is a naturally occurring compound involved in cell membrane and brain chemistry. Huperzia serrata, also called toothed clubmoss, is a plant that contains huperzine A, an alkaloid that acts on acetylcholine, a key neurotransmitter for memory and cognition.

The capsule also contains microcrystalline cellulose, magnesium stearate, and silica as 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: Age-related cognitive decline, Alzheimer disease, Cognitive function, Vascular dementia, Memory loss, Brain health — and 2 related terms.
  • The strongest evidence on file: Acetyl-l-carnitine is rated "Possibly Effective" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Acetyl-l-carnitine is rated "Possibly Effective" for Alzheimer disease.
  • Also on file: Alpha-gpc is rated "Possibly Effective" for Alzheimer disease.

Acetyl-L-carnitine is rated possibly effective for age-related cognitive decline, Alzheimer disease, alcohol use disorder, diabetic neuropathy, and depression based on the evidence we hold. Alpha-glycerylphosphorylcholine is possibly effective for Alzheimer disease, but evidence is insufficient for cognitive function, brain tumors, vascular dementia, and stroke.

No effectiveness ratings are documented for Huperzia serrata in our data. The blend as a whole has no separate effectiveness rating in our records.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Acetyl-L-carnitine is generally well tolerated in the short term, though long-term safety isn't fully established. Common side effects include agitation, dry mouth, headache, insomnia, and reduced appetite.

Some people report a fishy odor of urine, breath, or sweat. Gastrointestinal upset (nausea, vomiting, diarrhea, constipation) can occur but typically no more often than with placebo.

Alpha-glycerylphosphorylcholine is generally well tolerated short-term, but long-term safety is not fully established. Rare side effects include dizziness, headache, insomnia, and nausea.

One concern: oral use for 2 months or longer has been associated with an elevated stroke risk compared to non-users or shorter-term use. Huperzia serrata may cause dizziness, nausea, and sweating; product quality varies widely.

Safety information is insufficient; pregnancy and breastfeeding use is not recommended.

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?
  • 3 of the 3 matched ingredients can interact with medications — Toothed Clubmoss, Acetyl-l-carnitine, Alpha-gpc.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 358 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 Avipaxin, check with your pharmacist if you take any serotonergic drugs (like antidepressants), blood thinners such as warfarin or acenocoumarol, thyroid hormone replacement, cholinergic drugs (like donepezil), anticholinergic medications, or scopolamine patches. These are the main medication types with documented interactions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Avipaxin may be worth considering if you're exploring brain health support and have checked your medications first. Because of interactions with blood thinners, serotonergic drugs, thyroid medication, and certain Alzheimer disease and motion-sickness treatments, you really do need to talk with your pharmacist before starting.

Long-term safety data for all three ingredients is limited, so discuss your timeline and goals with your doctor.

Huperzia serrata2 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

Acetyl-L-Carnitine HCl4 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.

Likelihood Possible Evidence D

Alpha-Glycerylphosphorylcholine1 drug type · 16 drugs

Scopolamine (Transderm Scop)

Theoretically, alpha-GPC might decrease the effects of scopolamine.
A small clinical study shows that alpha-GPC can partially counteract the attention and memory impairment effects caused by scopolamine given intramuscularly. Whether alpha-GPC can decrease the beneficial anti-motion sickness effects of the scopolamine patch (Transderm Scop) is unclear.

Avipaxin by NS NeuroScience: Common Questions

Does Avipaxin by NS NeuroScience interact with any medications?
Yes. Based on its ingredients, Avipaxin has a known interaction with 358 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Avipaxin contains 3 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.
What is acetyl-L-carnitine supposed to do?
Acetyl-L-carnitine is an amino acid derivative that plays a role in brain energy production and neurotransmitter function. It's rated possibly effective for age-related cognitive decline, Alzheimer disease, depression, diabetic neuropathy, and alcohol use disorder based on the evidence we hold.
Can I take this if I'm on an antidepressant?
Not without checking first. Acetyl-L-carnitine may increase serotonin levels in the brain, which could raise the risk of serotonin syndrome if you're on a serotonergic antidepressant. Talk to your pharmacist about your specific medication before starting.
What side effects should I watch for?
The most common are agitation, dry mouth, headache, insomnia, and reduced appetite. Some people notice a fishy odor in their urine, breath, or sweat. Nausea, vomiting, or digestive upset can occur. Dizziness and sweating are possible with the Huperzia serrata ingredient.
Is it safe to take during pregnancy?
There isn't enough safety information for acetyl-L-carnitine and alpha-glycerylphosphorylcholine during pregnancy, so talk with your doctor before using either. Huperzia serrata specifically advises against use in pregnancy due to insufficient safety data.
What if I'm on a blood thinner like warfarin?
Acetyl-L-carnitine may increase how much warfarin (or acenocoumarol) thins your blood, raising your bleeding risk. You'll need your doctor's oversight and likely more frequent blood-clotting checks if you use both.
How long can I safely take this?
Long-term safety for all three ingredients is not fully established in our data. Both acetyl-L-carnitine and alpha-glycerylphosphorylcholine are generally well tolerated in studies, but there's a note that alpha-GPC use for 2 months or longer has been linked to elevated stroke risk. Discuss duration with your doctor.
