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 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Immune Factor E contains 4 active ingredients: goldthread (Coptis chinensis), two echinacea species (Echinacea angustifolia and Echinacea purpurea), and andrographis (Andrographis paniculata). The capsules also contain gelatin and purified water as inactive ingredients.

Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: promote body's natural immune defenses.
  • We looked for evidence on: Acute bronchitis, Coronavirus disease 2019 (COVID-19), Genital herpes, Gingivitis, Herpes labialis (cold sores), HIV/AIDS — and 4 related terms.
  • The closest evidence on file: Andrographis is rated "Insufficient Reliable Evidence To Rate" for Acute bronchitis (Natural Medicines).
  • Also on file: Andrographis is rated "Insufficient Reliable Evidence To Rate" for Influenza, Rhinosinusitis, Coronavirus disease 2019 (COVID-19).
  • Also on file: Echinacea is rated "Insufficient Reliable Evidence To Rate" for Herpes labialis (cold sores), Gingivitis, HIV/AIDS.

The data we hold shows insufficient reliable evidence to rate echinacea for anxiety, athletic performance, ADHD, burns, chronic fatigue syndrome, or migraine headache. Andrographis has possibly effective evidence for ulcerative colitis, tonsillopharyngitis, and osteoarthritis.

We don't have effectiveness ratings on file for goldthread or for the overall combination in this product, so the evidence isn't established in our data for most of what this supplement claims to do.

The evidence, ingredient by ingredient Goldthread Echinacea Andrographis

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 2 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.

Both echinacea species are generally well tolerated short-term, but common side effects include abdominal pain, constipation, diarrhea, heartburn, nausea, vomiting, and rashes. Allergic reactions are possible, especially if you're sensitive to ragweed or related plants (like chrysanthemums or daisies).

Rare but serious reactions—including severe allergies, hepatitis, and anaphylaxis—have been reported. Andrographis is also generally well tolerated short-term but causes similar digestive upset, rashes, and allergic reactions; side effects are more likely at higher doses or beyond 14 days of use.

Goldthread may be tolerated short-term by some adults, but human safety data are limited and product quality varies. Goldthread should be avoided in pregnancy because berberine may harm the fetus, and it should be avoided while breastfeeding because berberine passes to infants.

Andrographis safety data advise against use in pregnancy and breastfeeding. We don't have pregnancy or breastfeeding safety information on file for the echinacea species.

Echinacea angustifolia12 drug types · 816 drugs

Caffeine

Echinacea can increase plasma levels of caffeine by inhibiting its metabolism.
Echinacea seems to increase plasma concentrations of caffeine by around 30%. This is likely due to inhibition of cytochrome P450 1A2 (CYP1A2) by echinacea.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Echinacea might inhibit the metabolism of CYP1A2 and increase plasma levels of some drugs.
Echinacea appears to inhibit CYP1A2 enzymes in humans. Additionally, echinacea seems to increase plasma concentrations of caffeine, a CYP1A2 substrate, by around 30%. Theoretically, echinacea might increase levels of other drugs metabolized by CYP1A2.

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

Echinacea may induce hepatic CYP3A4 and inhibit intestinal CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Several clinical trials have shown that taking echinacea for up to one month does not significantly affect the metabolism of various CYP3A4 substrates, including midazolam, docetaxel, etravirine, lopinavir-ritonavir, and darunavir-ritonavir. However, other clinical research shows that echinacea may increase the clearance of midazolam, suggesting that echinacea might induce CYP3A4. The discrepancy is thought to be due to differing effects of echinacea on intestinal versus hepatic CYP3A4 enzymes. Echinacea appears to induce hepatic CYP3A4 but inhibit intestinal CYP3A4. In some cases, these effects might cancel each other out, but in others, drug levels may be increased or decreased depending on the level of effect at hepatic and intestinal sites. The effect of echinacea on CYP3A4 activity may differ depending on the CYP3A4 substrate.

Likelihood Possible Evidence B
Etoposide (Vepesid)

Echinacea may increase levels of etoposide.
In one report, concomitant use of etoposide and echinacea was associated with more severe thrombocytopenia than the use of etoposide alone, suggesting inhibition of etoposide metabolism. Etoposide is a cytochrome P450 3A4 (CYP3A4) substrate. Echinacea has variable effects on CYP3A4, but some studies have reported inhibition of the enzyme.

Likelihood Possible Evidence D
Immunosuppressants

Echinacea has immunostimulant activity which may interfere with immunosuppressant therapy.
Theoretically, echinacea may interfere with immunosuppressant therapy because of its immunostimulant activity.

Likelihood Possible Evidence B
Darunavir (Prezista)

Theoretically, echinacea may interfere with the metabolism of darunavir; however, a small clinical study found no effect.
Darunavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but administration of an E. purpurea root extract (Arkocapsulas Echinacea, Arkopharma) 500 mg four times daily for 14 days did not affect darunavir/ritonavir pharmacokinetics in 15 HIV-infected patients.

Likelihood Unlikely Evidence B
Dayquil Severe

Echinacea is reported to have varying effects on a number of Cytochrome P450 metabolizing enzymes in the liver, including CYP1A2 and CYP3A4, which play a role in acetaminophen and dextromethorphan metabolism (both contained in DayQuil Severe), respectively. Studies have reported both enzyme inhibition and induction, making it difficult to predict clinically significant drug interactions with reliability. Specific drug interaction studies reporting definitive results are rare, and potential drug interactions involving echinacea should likely be taken on a case-by-case basis. Based on what we know about how acetaminophen and dextromethorphan are metabolized, the risk of a clinically significant interaction between echinacea and DayQuil Severe is low.

Likelihood Unlikely Evidence A
Docetaxel (Taxotere)

Theoretically, echinacea may interfere with the metabolism of docetaxel; however, a small clinical study found no effect.
Docetaxel is metabolized by cytochrome P450 3A4 (CYP3A4). Echinacea has variable effects on CYP3A4, but taking E. purpurea whole plant extract (Echinaforce, A. Vogel Biopharma AG) 20 drops three times daily for 2 weeks did not alter the pharmacokinetics of docetaxel in one clinical study.

Likelihood Unlikely Evidence B
Etravirine (Intelence)

Theoretically, echinacea may interfere with the metabolism of etravirine; however, a small clinical study found no effect.
Etravirine is metabolized by cytochrome P450 3A4 (CYP3A4). Echinacea has variable effects on CYP3A4, but taking E. purpurea root extract (Arkocapsulas Echinacea, Arkopharma) 500 mg three times daily for 14 days did not alter the pharmacokinetics of etravirine in HIV-infected patients.

Likelihood Unlikely Evidence B
Lopinavir/Ritonavir (Kaletra)

Theoretically, echinacea may interfere with the metabolism of lopinavir; however, a small clinical study found no effect.
Lopinavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but taking E. purpurea (Echinamide, Natural Factors Nutritional Products, Inc.) 500 mg three times daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in healthy volunteers.

Likelihood Unlikely Evidence B
Midazolam (Versed)

Theoretically, echinacea may increase the metabolism of intravenous midazolam.
Echinacea induces hepatic CYP3A4 and might decrease plasma levels of midazolam by about 20%, reducing the effectiveness of intravenous midazolam. Echinacea also appears to inhibit intestinal CYP3A4, which could theoretically increase the bioavailability of oral midazolam. This may cancel out the decrease in availability caused by induction of hepatic CYP3A4, such that overall plasma levels after oral administration of midazolam are not affected by echinacea.

Likelihood Possible Evidence B
Warfarin (Coumadin)

Echinacea seems to increase the clearance of warfarin, although the effect may not be clinically significant.
Preliminary clinical research in healthy male volunteers suggests that taking echinacea increases the clearance of the active S-isomer of warfarin after a single dose of warfarin, but there was not a clinically significant effect on the INR.

Likelihood Possible Evidence B
Echinacea angustifolia full monograph & interactions

Coptis chinensis2 drug types · 643 drugs

Cyclosporine (Neoral, Sandimmune)

Berberine, a constituent of goldthread, can reduce metabolism of cyclosporine and increase serum levels. It might inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine.

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

There's very preliminary evidence that berberine, a constituent of goldthread, might inhibit cytochrome P450 3A4 (CYP3A4) enzyme. So far, this interaction has not been reported in humans. However, watch for an increase in the levels of drugs metabolized by CYP3A4 in patients taking goldthread. Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), clarithromycin (Biaxin), indinavir (Crixivan), sildenafil (Viagra), triazolam (Halcion), and numerous others. Use goldthread cautiously or avoid in patients taking these drugs.

Likelihood Possible Evidence D
Coptis chinensis full monograph & interactions

Andrographis paniculata6 drug types · 413 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, andrographis might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Animal and laboratory studies suggest that andrographis has antiplatelet effects.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, andrographis might increase the risk of hypotension when used with antihypertensive drugs.
Animal research suggests that andrographis has hypotensive effects.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, andrographis might interfere with the effects of immunosuppressive drugs.
Laboratory research suggests that andrographolide has immunostimulant activity.

Likelihood Possible Evidence D
Celecoxib (Celebrex)

Theoretically, andrographis extract might increase the maximum concentration and time to peak concentration of celecoxib. The clinical significance of these changes is unclear.
Animal research suggests that andrographis extract taken orally increases the maximum concentration and time to peak concentration of celecoxib but does not appear to impact the area under the curve.

Likelihood Possible Evidence D
Etoricoxib (Arcoxia)

Theoretically, andrographis might decrease the absorption of etoricoxib, although the clinical significance is unclear.
Animal research shows that andrographis extract, or the constituent andrographolide, taken orally with etoricoxib decreases the bioavailability of etoricoxib. However, this reduced bioavailability is not correlated with a reduction in the anti-inflammatory effects of etoricoxib in arthritic mice models. The clinical significance of this interaction is unclear.

Likelihood Possible Evidence D
Glipizide (Glucotrol)

Theoretically, andrographis extract might increase the maximum concentration and area under the curve of glipizide; however, opposite effects are seen with the constituent, andrographolide. The clinical significance of this interaction is unclear.
Animal research suggests that andrographis extract taken orally with glipizide in diabetes-induced rats increases the maximum concentration and area under the curve of glipizide. However, the opposite effect is seen with the constituent, andrographolide, in which the maximum concentration and area under the curve are decreased when taken with glipizide.

Immune Factor E by Longevity Medical Clinic: Common Questions

Does Immune Factor E by Longevity Medical Clinic interact with any medications?
Yes. Based on its ingredients, Immune Factor E has a known interaction with 1,031 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Immune Factor E contains 4 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?
No—andrographis should be avoided in pregnancy because animal studies raise concerns about reproductive effects. Goldthread should also be avoided because its berberine content may harm the fetus. We don't have pregnancy safety data on file for the echinacea species, so talk with your doctor or pharmacist for personalized advice before taking this product if you're pregnant or planning to become pregnant.
Can I take this while breastfeeding?
Goldthread and andrographis should be avoided while breastfeeding—berberine passes into breast milk and may harm infants, and andrographis safety data are insufficient. We don't have breastfeeding safety information on file for the echinacea species. Talk with your doctor or pharmacist about whether this product is right for you.
What's goldthread in here for?
Goldthread (Coptis chinensis) is one of the four active ingredients in this product. We don't have effectiveness ratings on file for it, so the evidence isn't established in our data for what role it plays in the formula.
Does echinacea really work for colds?
The data we hold shows insufficient reliable evidence to rate echinacea for any of the conditions we've checked—including colds and cold-related symptoms. So we can't say whether it works for those purposes based on the information available to us.
What are the most common side effects?
The most common side effects from the echinacea and andrographis in this product include abdominal pain, diarrhea, heartburn, nausea, vomiting, rashes, and headache. Allergic reactions—ranging from rashes to severe anaphylaxis—are possible, especially if you're sensitive to ragweed or related plants. Serious side effects like hepatitis are rare but have been reported.
Is this safe to take long-term?
The data show limited long-term safety information for all four ingredients. Goldthread, echinacea, and andrographis are all best tolerated short-term. Andrographis side effects are more likely if you take high doses or use it for more than 14 days. Talk with your pharmacist about how long is safe for you.
