HelloPharmacist Scorecard of Immune Support by Lindberg
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
Immune Support is a 4-ingredient capsule combining three mushroom extracts and a polysaccharide compound. Reishi mushroom extract, maitake mushroom extract, and shiitake mushroom extract each bring different compounds—polysaccharides and beta-glucans among them—traditionally associated with immune function.
Beta 1,3/1,6 glucan is a carbohydrate extracted from yeast or mushrooms that also appears in several of the mushroom ingredients themselves. The capsule also contains inactive ingredients (gelatin, magnesium stearate, and silicon dioxide) as binders and flow agents.
Does it work?
Not established
The evidence for this product's active ingredients is mixed. Beta-glucan shows likely effectiveness for high cholesterol (dyslipidemia) and coronary heart disease based on clinical research.
For the mushroom extracts, the data on file doesn't establish effectiveness for most conditions we have ratings for—the evidence is either insufficient to judge or points to possible ineffectiveness, as with reishi mushroom and cholesterol. Some individual mushroom compounds have shown promise in laboratory or animal research for immune support and other conditions, but human trial evidence for the product's stated immune-support purpose isn't on file in our data.
How safe is it?
Well-documented data
The three mushroom extracts are generally well tolerated when taken by mouth in the short term, though long-term safety data for supplements is limited. The most common side effects are mild: dizziness, dry mouth, nausea, stomach upset, rash, and diarrhea appear across the mushroom ingredients.
Shiitake, especially if raw or in concentrated supplement form rather than as food, carries a rare risk of a skin reaction called shiitake dermatitis. Beta-glucan from food sources is generally well tolerated; concentrated supplements lack safety data, so caution is advised.
During pregnancy, safety data doesn't exist for these concentrated mushroom supplements, so they're best avoided. The same applies to breastfeeding.
If you're pregnant or nursing, talk with your doctor or pharmacist before taking this product.
Meds to double-check
Moderate interaction found
Before you take Immune Support, check with your pharmacist or doctor if you're on warfarin (Coumadin) or other blood thinners, as maitake mushroom may boost their effect. Blood pressure medications, diabetes medications, and immune-suppressing drugs (used after transplant or for autoimmune conditions) all interact with ingredients in this product at Moderate severity and should be reviewed.
Additionally, if you take psychiatric or heart medications that your liver breaks down through the CYP2D6 pathway, shiitake mushroom may slow their clearance, though this is theoretical in humans.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
Immune Support may be worth considering if you're looking for a mushroom-based immune formula, though the human evidence for its main purpose isn't well established in our data. If you take blood pressure medications, diabetes medications, warfarin, or drugs that suppress the immune system, this product needs a careful check-in with your pharmacist or doctor first—the mushroom extracts can interact with those drug classes.
Pregnant or breastfeeding people should avoid it and speak with their healthcare provider instead.

Immune Support by Lindberg Drug Interactions
HelloPharmacist Interaction Report
Lindberg's Immune Support contains four active ingredients—reishi mushroom, maitake mushroom, shiitake mushroom, and beta-glucan—that together carry documented interactions with several medication types.
The most serious is maitake mushroom's potential to increase warfarin's blood-thinning effect (anticoagulant effect), a Moderate-severity interaction documented in a case report where a patient's anticoagulation level became dangerously elevated after taking maitake.
Read the full breakdown — every affected drug type, severity by severity
Beyond warfarin, reishi and maitake mushroom both may lower blood pressure further when combined with blood pressure medications (antihypertensive drugs), and both may increase the risk of low blood sugar (hypoglycemia) if you're taking diabetes medications. Shiitake mushroom could theoretically reduce how well immune-suppressing medications work if you're taking them after an organ transplant or for an autoimmune condition.
Shiitake may also slow how your liver clears certain psychiatric and heart medications metabolized by the CYP2D6 enzyme, though this hasn't been confirmed in people yet. Beta-glucan shares the blood pressure and immunosuppressant concerns with the mushroom extracts.
Additionally, we could not check for interactions with several inactive ingredients in the capsule (gelatin, magnesium stearate, silicon dioxide). Altogether, these interactions span 654 individual medications.

For each ingredient in Immune Support 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.
Reishi Mushroom extract
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.
Shiitake Mushroom extract
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.
Beta 1,3/1,6 Glucan
Antihypertensive Drugs
Theoretically, taking beta-glucans with antihypertensive drugs might increase the risk of hypotension.
Clinical research shows that taking beta-glucans may reduce systolic and diastolic blood pressure in some hypertensive individuals.
Immunosuppressants
Theoretically, beta-glucans might interfere with immunosuppressive therapy.
Some clinical research shows that beta-glucans have immunostimulant effects.
Maitake Mushroom extract
Antidiabetes Drugs
Theoretically, combining maitake mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that taking maitake mushroom polysaccharide (MMP) can lower blood glucose levels in patients with types 2 diabetes.
Antihypertensive Drugs
Theoretically, combining maitake mushroom with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that maitake mushroom can lower blood pressure.
Warfarin (Coumadin)
There is limited evidence that maitake mushroom may increase the anticoagulant effects of warfarin.
In a case report, a patient previously stabilized on warfarin developed an elevated international normalized ratio (INR) of 5.1 after taking maitake mushroom (Grifron-Pro Maitake D-Fraction) 1 drop/kg daily in three divided doses for one week. The elevated INR resolved after holding warfarin for two days, then reducing the dose by 11%. It is thought that the beta-glucan constituent of maitake mushroom might cause warfarin dissociation from proteins, resulting in increased free warfarin levels and increased warfarin effects.
