HelloPharmacist Scorecard of Huperzine A with Eleuthero by Solaray
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
This supplement contains three active ingredients. Huperzine A is an alkaloid compound extracted from a moss species; it works by inhibiting an enzyme that normally breaks down acetylcholine, a brain chemical involved in memory and learning.
Eleuthero (also called Siberian ginseng) is an herbal root extract used traditionally for stamina and stress resilience. Lecithin is a phospholipid — a fat-like compound found naturally in eggs and soybeans — that your body uses to build and maintain cell membranes, including in the brain.
The capsules also contain inactive ingredients: cellulose, maltodextrin, silica, and magnesium stearate, which are fillers and binders.
Does it work?
Moderate evidence
Huperzine A is rated possibly effective for Alzheimer disease based on available evidence. The evidence for other uses — cognitive impairment, vascular dementia, memory, depression, and athletic performance — is currently insufficient to rate.
Eleuthero is rated possibly effective for genital herpes. For its other marketed uses — familial Mediterranean fever, bipolar disorder, osteoporosis, and chronic fatigue syndrome — the evidence is insufficient.
Lecithin is rated likely ineffective for Alzheimer disease and has insufficient evidence for age-related cognitive decline, anxiety, bipolar disorder, and liver problems related to total parenteral nutrition.
How safe is it?
Well-documented data
Huperzine A is a pharmacologically active compound and should be used with care and medical guidance. It's generally well tolerated orally, but can cause dose-dependent cholinergic side effects — blurred vision, constipation, diarrhea, dizziness, dry mouth, insomnia, nausea, sweating, and vomiting — and may slow your heart rate.
Avoid it in pregnancy and while breastfeeding, as safety data is insufficient. Eleuthero is generally well tolerated short-term, but long-term safety is not well established.
Avoid it in pregnancy and while breastfeeding. Common side effects include diarrhea, heartburn, stomach upset, headache, nausea, and rash.
Nervousness and anxiety have been reported in some people, especially at higher doses; it may also raise blood pressure. Lecithin is generally well tolerated and likely safe in pregnancy and lactation.
Orally it may cause abdominal pain, diarrhea, fullness, and nausea. If you have an egg or soy allergy, lecithin can trigger allergic skin reactions.
Meds to double-check
Moderate interaction found
Check these medication types before you start: digoxin or other heart drugs, blood thinners or antiplatelet drugs (like warfarin or clopidogrel), diabetes medications, immunosuppressants, and drugs your liver metabolizes using CYP1A2, CYP2C9, or CYP2D6 enzymes — anticholinergic and cholinergic drugs are also a concern with huperzine A specifically. Your pharmacist can search your full list on this page.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product targets brain function and memory, with huperzine A as the most studied ingredient for Alzheimer disease. It's not appropriate for pregnancy or breastfeeding.
If you take digoxin, blood thinners, diabetes medications, or drugs metabolized by your liver (a very common category), check your exact medications below before starting. Talk to your pharmacist — these are active compounds, and the combination deserves a quick review of your personal medication list.

Huperzine A with Eleuthero by Solaray Drug Interactions
HelloPharmacist Interaction Report
Huperzine A with Eleuthero by Solaray contains three ingredients, two of which have documented interactions with medications.
Eleuthero is the biggest concern — it theoretically may increase levels of several types of drugs your liver metabolizes (CYP1A2, CYP2C9, and CYP2D6 substrates) and may affect how P-glycoprotein transporters move drugs through your body. The most serious documented interaction is Moderate: eleuthero may raise digoxin levels if you take that heart medication.
Read the full breakdown — every affected drug type, severity by severity
Eleuthero also carries Moderate interactions with blood thinners (anticoagulants and antiplatelet drugs) — it may increase bleeding risk — and with diabetes medications, since it may lower blood sugar on its own. It theoretically may interfere with immunosuppressants and could affect how your body handles other drugs your liver processes using CYP2D6, though human research found no effect at typical doses.
Huperzine A has Moderate interactions with anticholinergic drugs (it may reduce their effect) and with cholinergic drugs (it may add to their effects and side effects). Lecithin, the third ingredient, has no known interactions documented in our data.
Altogether, these interactions span 1,253 individual medications. Use the search tool on this page to check your exact medications before starting.

Read the full Huperzine A + Acetaminophen, Chlorpheniramine, Phenylephrine interactionEach ingredient & the kinds of drugs it affects
For each ingredient in Huperzine A with Eleuthero with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Eleuthero
Anticoagulant/Antiplatelet Drugs
Theoretically, eleuthero may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research shows that a constituent of eleuthero, dihydroxybenzoic acid, appears to inhibit platelet aggregation. Concomitant use with anticoagulant or antiplatelet drugs might increase the risk of bleeding. This effect has not been reported in humans.
Antidiabetes Drugs
Theoretically, eleuthero might have additive effects when used with antidiabetes drugs.
Animal research suggests that certain constituents of eleuthero have hypoglycemic activity in both healthy and diabetic animals. A small study in adults with type 2 diabetes also shows that taking eleuthero for 3 months can lower blood glucose levels. However, one very small study in healthy individuals shows that taking powdered eleuthero 3 grams, 40 minutes prior to a 75-gram oral glucose tolerance test, significantly increases postprandial blood glucose levels when compared with placebo. These contradictory findings might be due to patient-specific variability and variability in active ingredient ratios.
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, eleuthero might increase levels of drugs metabolized by CYP1A2.
In vitro and animal research suggest that standardized extracts of eleuthero inhibit CYP1A2. This effect has not been reported in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2C9.
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2C9. This effect has not been reported in humans.
Digoxin (Lanoxin)
Eleuthero might increase serum digoxin levels and increase the risk of side effects.
In one case report, a 74-year-old male who was stabilized on digoxin presented with an elevated serum digoxin level after starting an eleuthero supplement, without symptoms of toxicity. After stopping the supplement, serum digoxin levels returned to normal. It is not clear whether this was due to a pharmacokinetic interaction or to interference with the digoxin assay. Although the product was found to be free of digoxin and digitoxin, it was not tested for other contaminants.
Immunosuppressants
Theoretically, eleuthero might interfere with immunosuppressive drugs because of its immunostimulant activity.
Animal and in vitro research shows that eleuthero extracts have immunomodulatory effects, including increasing cellular and humoral activity.
P-Glycoprotein Substrates
Theoretically, eleuthero might increase levels of P-glycoprotein substrates.
In vitro research suggests that eleuthero can inhibit the multi-drug transporter protein, P-glycoprotein. However, it is too soon to tell if this is clinically important. This interaction has not been reported in humans.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2D6.
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2D6. However, research in healthy human volunteers has found that taking eleuthero 485 mg twice daily for 14 days does not inhibit CYP2D6 drug metabolism.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, eleuthero might increase levels of drugs metabolized by CYP3A4.
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP3A4. However, research in healthy human volunteers has found that taking eleuthero 485 mg twice daily for 14 days does not inhibit CYP3A4 drug metabolism.
Organic Anion-Transporting Polypeptide Substrates (Oatp)
Theoretically, eleuthero might decrease levels of drugs metabolized by OATP.
In vitro research suggests that eleuthero inhibits OATP2B1, which might reduce the bioavailability of oral drugs that are substrates of OATP2B1. Due to the weak inhibitory effect identified in this study, this interaction is not likely to be clinically significant.
Huperzine A
Anticholinergic Drugs
Theoretically, huperzine A might decrease the effects of anticholinergic drugs.
Huperzine A has acetylcholinesterase (AChE) inhibiting effects. In animal models, huperzine A reversed cognitive deficits induced by scopolamine, an anticholinergic drug.
Cholinergic Drugs
Theoretically, concurrent use of huperzine A with cholinergic drugs might increase the effects and side effects of these medications.
Huperzine A can inhibit acetylcholinesterase (AChE) and might cause cumulative effects if used with cholinergic drugs.
