HelloPharmacist Scorecard of Superfood Mushroom Reishi by New Chapter

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

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: reishi mushroom, a fungus used in traditional herbal medicine. The capsule itself is made from pullulan, carrageenan, water, and potassium chloride—all inactive ingredients that form the shell and help deliver the reishi.

Does it work?

Not established
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
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 — see Reishi Mushroom's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Immune support, stress and sleep wellness.
  • We looked for evidence on: Insomnia, Stress, Psychological well-being, Chronic fatigue syndrome (CFS), Cancer-related fatigue, Sleep quality — and 2 related terms.
  • The closest evidence on file: Reishi Mushroom is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS) (Natural Medicines).
  • Also on file: Reishi Mushroom is rated "Insufficient Reliable Evidence To Rate" for Cancer-related fatigue, Insomnia, Stress, Psychological well-being.

The evidence for reishi's effectiveness is limited and mixed. For high cholesterol (hyperlipidemia), reishi is rated possibly ineffective based on available research.

For altitude sickness, Alzheimer disease, and athletic performance, there isn't enough reliable evidence yet to rate whether it works. If you're thinking about reishi for any of these, talk with your pharmacist about what the current research actually shows.

The evidence, ingredient by ingredient Reishi Mushroom

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Reishi is generally well tolerated in the short term. The most common side effects are dizziness, dry mouth, itching, nausea, rash, and stomach upset.

Some people report sore throat, runny nose, or respiratory allergy to reishi spores; rarely, insomnia and headache occur. Long-term safety hasn't been well studied, so caution is advised with extended use.

Reishi is not recommended during pregnancy or breastfeeding—there isn't enough safety data to know either way. If you're pregnant, planning to become pregnant, or breastfeeding, talk with your pharmacist or doctor before taking it.

Side effects, ingredient by ingredient Reishi Mushroom

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?
  • 1 of the 1 matched ingredient can interact with medications — Reishi Mushroom.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 375 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 you take this product, double-check it with your pharmacist if you're on blood thinners (like warfarin or aspirin), blood pressure medications, or diabetes drugs—all Moderate-severity interactions. The interaction risk with blood thinners grows at higher doses, so your exact dose matters.

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.

Reishi may be worth considering if you're exploring traditional mushroom supplements, but the evidence for most claimed benefits is weak or missing. If you take blood thinners, blood pressure meds, or diabetes drugs, check with your pharmacist first—reishi can interact with all three.

Long-term safety is an open question, so don't plan on taking it indefinitely without guidance.

Reishi3 drug types · 375 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Superfood Mushroom Reishi by New Chapter: Common Questions

Does Superfood Mushroom Reishi by New Chapter interact with any medications?
Yes. Based on its ingredients, Superfood Mushroom Reishi has a known interaction with 375 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Superfood Mushroom Reishi contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 on a blood thinner like warfarin?
Not without checking first. Reishi at higher doses can increase bleeding risk when combined with blood thinners—that's a Moderate-severity interaction. Talk to your pharmacist before starting; they may need to monitor you.
What side effects should I expect?
Most common are dizziness, dry mouth, itching, nausea, rash, and stomach upset. A small number of people report sore throat, runny nose, or rarely insomnia and headache. Stop and call your pharmacist if anything feels off.
Is reishi safe long-term?
It's generally well tolerated in the short term, but long-term safety hasn't been studied much. If you're thinking about taking it regularly for months or years, ask your pharmacist whether that's a good fit for you.
Can I take this while I'm pregnant or breastfeeding?
No—there isn't enough safety data. It's best avoided during pregnancy and while breastfeeding. Talk with your doctor or pharmacist if you're pregnant, planning to become pregnant, or nursing.
Does reishi actually work for high cholesterol?
The evidence says it's possibly ineffective for that. If lower cholesterol is your goal, talk with your doctor about what treatments are proven to work.
