HelloPharmacist Scorecard of Immune Optimizer by Jarrow Formulas
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
Low disclosure
Immune Optimizer contains seven active ingredients: Lion's Mane mushroom, Reishi, Cordyceps, King Trumpet mushroom, Shiitake mushroom, a PeakO2 proprietary blend, Turkey Tail mushroom, and AP-Bio (andrographis). These are mushroom extracts and herbal compounds traditionally used to support immune function.
The product also includes inactive ingredients — microcrystalline cellulose, hydroxypropyl methylcellulose, myceliated oats, magnesium stearate, and silicon dioxide — which serve as binders and capsule materials.
Does it work?
Not established
The evidence for most of these ingredients is limited. For Lion's Mane, Cordyceps, and King Trumpet, we don't have enough reliable data to rate their effectiveness for any of the conditions they're marketed for — that includes cognitive function, athletic performance, and various cancers.
Cordyceps is actually rated possibly ineffective for athletic performance. Shiitake is rated possibly ineffective for dental plaque.
AP-Bio (andrographis) shows promise: it's rated possibly effective for sore throat (tonsillopharyngitis), ulcerative colitis, and osteoarthritis, but evidence for other uses remains insufficient. We hold no effectiveness data for Reishi or Turkey Tail.
How safe is it?
Well-documented data
Lion's Mane, Cordyceps, and King Trumpet are generally well tolerated but have not been studied long-term in supplement form. All three carry a caution during pregnancy and should be avoided while breastfeeding due to insufficient safety data.
Common side effects across these mushrooms include gastrointestinal discomfort, nausea, and diarrhea. Shiitake is generally safe when eaten as food but should be approached cautiously in concentrated supplement doses; raw shiitake can cause a skin condition called shiitake dermatitis, and workers handling the mushroom have reported allergic reactions including asthma and pneumonia.
AP-Bio (andrographis) is often well tolerated short-term but should be avoided in pregnancy due to concerns about reproductive effects, and evidence is insufficient for breastfeeding. Andrographis most commonly causes gastrointestinal discomfort, altered taste, diarrhea, dizziness, fatigue, headache, nausea, rash, and itching; rare serious reactions include anaphylaxis and severe skin eruptions like Stevens-Johnson syndrome.
Meds to double-check
Moderate interaction found
Before taking Immune Optimizer, double-check with your pharmacist if you're on blood thinners or antiplatelet drugs (like warfarin, apixaban, aspirin, or clopidogrel) — Lion's Mane, Cordyceps, King Trumpet, and AP-Bio may increase bleeding risk. Also flag blood sugar medications (like metformin or insulin), drugs that suppress your immune system (like cyclosporine), blood pressure medications, and any psychiatric or heart drugs metabolized by your liver's CYP2D6 enzyme.
Specific interactions exist with celecoxib (Celebrex), etoricoxib (Arcoxia), and glipizide (Glucotrol).
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
This product may be worth considering if you're interested in traditional mushroom and herbal immune support and have no relevant medications. But if you take blood thinners, diabetes drugs, blood pressure medications, immune-suppressing drugs, or certain psychiatric or heart medications, you need to check with your pharmacist first — the interactions are real and could affect how your drugs work.
Pregnancy and breastfeeding are times to skip it and talk with your doctor.

Immune Optimizer by Jarrow Formulas Drug Interactions
HelloPharmacist Interaction Report
Immune Optimizer by Jarrow Formulas contains seven ingredients, and we've found documented interactions with medications for five of them.
The most serious concern is with blood thinners (anticoagulants) and antiplatelet drugs like aspirin or clopidogrel — Lion's Mane, Cordyceps, King Trumpet, and AP-Bio (andrographis) may all theoretically increase bleeding risk. Lion's Mane, Cordyceps, King Trumpet, and AP-Bio also interact with blood sugar medications (antidiabetes drugs) and drugs that suppress your immune system (immunosuppressants), with the potential to cause low blood sugar or interfere with transplant or autoimmune therapy.
AP-Bio additionally may lower blood pressure when used with blood pressure medications, and shiitake may affect how your body metabolizes certain psychiatric and heart medications (CYP2D6 substrates). Altogether, these interactions span 657 individual medications.
Read the full breakdown — every affected drug type, severity by severity
We could not check Reishi or Turkey Tail — we hold no interaction data for those ingredients. For the others, the most frequently affected drug types are blood thinners, immune-suppressing medications, and blood sugar drugs, all rated Moderate severity.
AP-Bio also carries Minor-severity interactions with specific pain relievers (etoricoxib and celecoxib) and a diabetes medication (glipizide).

For each ingredient in Immune Optimizer 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.
AP-Bio
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.
Antihypertensive Drugs
Theoretically, andrographis might increase the risk of hypotension when used with antihypertensive drugs.
Animal research suggests that andrographis has hypotensive effects.
Immunosuppressants
Theoretically, andrographis might interfere with the effects of immunosuppressive drugs.
Laboratory research suggests that andrographolide has immunostimulant activity.
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.
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.
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.
Reishi
Anticoagulant/Antiplatelet Drugs
Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does.
Antidiabetes Drugs
Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.
Animal research suggests that reishi mushroom decreases blood sugar. However, in patients with type 2 diabetes, taking reishi mushroom does not reduce fasting glucose levels, and its effects on glycated hemoglobin are inconsistent.
Antihypertensive Drugs
Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.
Reishi mushroom has shown hypotensive activity in animal research. Clinical evidence suggests that reishi mushroom reduces blood pressure in some, but not all, patients with hypertension.
Lion's Mane
Anticoagulant/Antiplatelet Drugs
Theoretically, lion's mane mushroom may increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
In vitro research suggests that lion's mane mushroom extracts can inhibit platelet aggregation.
Antidiabetes Drugs
Theoretically, lion's mane mushroom may have additive effects when used with antidiabetes drugs.
Animal research suggests that an aqueous extract of lion's mane mushroom can reduce serum glucose and increase serum insulin.
Immunosuppressants
Theoretically, concurrent use of lion's mane mushroom might interfere with immunosuppressive therapy.
In animal and in vitro research, lion's mane mushroom polysaccharides stimulate the immune system.
Shiitake
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, shiitake mushroom might decrease levels of drugs metabolized by CYP2D6.
In vitro studies suggest that the shiitake mushroom extract AHCC might induce the CYP2D6 enzyme. This effect has not been reported in humans.
Immunosuppressants
Theoretically, taking shiitake mushroom might decrease the effects of immunosuppressive therapy.
In vitro evidence suggests that shiitake mushroom extracts stimulate immune function.
Cordyceps
Anticoagulant/Antiplatelet Drugs
Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
In vitro and animal research suggests that cordyceps extract inhibits platelet aggregation and function. However, this interaction has not been reported in humans.
Immunosuppressants
Theoretically, concurrent use of cordyceps might interfere with immunosuppressive therapy.
Animal and in vitro research suggests that cordyceps stimulates the immune system. However, limited clinical research suggests that taking cordyceps may lower the necessary therapeutic dose of the immunosuppressant cyclosporine, which suggests that cordyceps may have an immunosuppressive effect.
Testosterone
Theoretically, concurrent use of cordyceps and testosterone might have additive effects.
Animal research suggests that cordyceps can increase testosterone levels. The clinical significance of this finding is unclear.
