HelloPharmacist Scorecard of Full Spectrum Chaga Mushroom 400 mg by Swanson

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 30, 2026

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: chaga mushroom extract at 400 mg per capsule. Chaga is a fungus that grows on birch trees and has been used traditionally in foods and teas.

The capsule also holds inactive ingredients — brown rice flour, gelatin, magnesium stearate, and silica — that help form and deliver the supplement.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: immune health.
  • We looked for evidence on: immune function, infection resistance, immune response.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for chaga's effectiveness isn't yet established in the data we hold. The product is marketed for cardiovascular disease, diabetes, and COVID-19, but the scientific evidence for these uses rates as insufficient to make a reliable call either way.

If you're considering chaga for a specific health goal, it's worth talking that over with your doctor or pharmacist to see what the current research supports.

The evidence, ingredient by ingredient Chaga

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.

Chaga is generally used in foods and teas, but human safety data are limited. A few risks have been reported: there have been cases of kidney failure and kidney injury linked to very high chaga consumption, which contains large amounts of oxalate (a compound that can build up in the kidneys).

The safety data advise against chaga during pregnancy and while breastfeeding because there isn't enough information to know whether it's safe.

Side effects, ingredient by ingredient Chaga

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 — Chaga.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 327 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.

Check with your doctor or pharmacist before taking this product if you use blood thinners or antiplatelet drugs, immunosuppressants, or antidiabetes medications. No interactions are documented for the other medications you might take, but that doesn't mean none exist — it's an absence of data, not proof of safety.

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.

Chaga may be worth considering if you're interested in traditional mushroom supplements, but check your exact medications first — especially blood thinners, immunosuppressants, and diabetes drugs. Avoid it during pregnancy or breastfeeding.

Talk with your doctor or pharmacist before you start, particularly if you have a history of kidney problems or take any prescription medications.
