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 (Ganoderma Lucidum), at 450 mg per capsule. The capsule itself is made from gelatin and water.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Reishi Mushroom product and its label doesn't state a use — see Reishi Mushroom's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

For the uses we have data on, reishi shows mixed or weak evidence. It is rated possibly ineffective for high cholesterol (hyperlipidemia).

For altitude sickness, Alzheimer disease, and athletic performance, we don't have enough reliable evidence to know whether it works.

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, but long-term safety hasn't been studied well, so we can't say much about taking it for months or years. The most common side effects are dizziness, dry mouth, itching, nausea, rash, and stomach upset.

Some people report sore throat and runny nose, and respiratory allergy to reishi spores can happen. Rare symptoms include insomnia and headache.

There isn't enough safety data to know whether reishi is safe in pregnancy or while breastfeeding, so the guidance is to avoid it during both. If you're pregnant, planning pregnancy, or nursing, talk with your doctor or pharmacist before taking this product.

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 start, double-check your blood pressure medications (antihypertensives), blood thinners (anticoagulants and antiplatelet drugs), and diabetes medications (antidiabetes drugs) with your own doctor or pharmacist — all three drug types interact with reishi at Moderate severity.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Reishi may be worth considering if you're curious about its potential effects, but it's not proven effective for most of the conditions it's marketed for. The real caution is if you take blood pressure drugs, blood thinners, or diabetes medications — you need to check with your own doctor or pharmacist first, because reishi can affect how those drugs work.

Steer clear during pregnancy and breastfeeding.

Reishi Mushroom3 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.

Reishi Mushroom (Ganoderma Lucidum) 450 mg by TerraVita Premium Collection: Common Questions

Does Reishi Mushroom (Ganoderma Lucidum) 450 mg by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Reishi Mushroom (Ganoderma Lucidum) 450 mg 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?
Reishi Mushroom (Ganoderma Lucidum) 450 mg 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.
What does reishi mushroom actually do?
We have evidence that reishi may lower blood pressure and blood sugar in some people, though the results are mixed. For high cholesterol and other conditions like Alzheimer disease or athletic performance, the evidence is too weak or missing to say whether it works.
What are the most common side effects?
Dizziness, dry mouth, itching, nausea, rash, and stomach upset are the most commonly reported. Some people also get a sore throat or runny nose. Rarely, people experience insomnia or headache.
Can I take this while pregnant or breastfeeding?
No — there isn't enough safety data, so the guidance is to avoid it during pregnancy and while breastfeeding. Talk with your doctor or pharmacist if you're pregnant, planning pregnancy, or nursing.
Is this safe to take long-term?
Short-term use is generally well tolerated, but long-term safety hasn't been well studied, so we don't have good information about taking it for months or years.
Does dose matter for interactions?
Yes — for blood thinners, the difference between 1.5 grams and 3 grams daily matters. At 1.5 grams it doesn't thin blood, but at 3 grams it does. This product is 450 mg per capsule, so talk with your doctor or pharmacist about how many you'd take and whether that's a concern with your medications.
