HelloPharmacist Scorecard of Organic Chaga Mushroom by Dr. Mercola

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 Oct 8, 2026

What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 2 of its 3 active ingredients.
  • “Polysaccharides” is listed as a grouped ingredient — the label gives one combined amount (40 mg) without saying how much of each component you get.
  • “Chaga Mushroom Blend” is a proprietary blend — the label gives one combined amount (500 mg) without saying how much of each component you get.
  • “Chaga, Powder” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

The active ingredients listed are polysaccharides, polyphenols, beta-glucan, chaga mushroom blend, chaga extract, and chaga powder. Beta-glucan and chaga extract are the two components with interaction and safety data on file here.

Polysaccharides, the chaga mushroom blend, and chaga powder are listed as group entries, so their individual components are the ones that appear in the data. The product also lists inactive ingredients: gum acacia, tapioca dextrose, sunflower lecithin, insulin, tapioca maltodextrin, palm oil, guar gum, and carnauba wax.

These are non-active additives that help form the tablet or pill.

Does it work?

Strong evidence
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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Strong

Strong clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Beta-glucans) (Natural Medicines).
  • On file: Dyslipidemia — rated "Likely Effective" (Beta-glucans) (Natural Medicines).

For beta-glucan, the data rates the evidence as Likely Effective for dyslipidemia (abnormal blood fats) and coronary heart disease (CHD). For chaga, the data lists cardiovascular disease (CVD), diabetes, and coronavirus disease 2019 (COVID-19) as Insufficient Reliable Evidence To Rate, meaning there is not enough reliable evidence to judge whether it works for these uses.

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Beta-glucans from food sources are generally well tolerated. Concentrated supplements lack safety data, so the data advises caution.

Skin reactions and contact dermatitis have been reported with a topical beta-glucan cream, and in one pediatric trial one of 44 patients had a temporary rise in liver enzymes after taking oral beta-glucans. Chaga is generally used in foods and teas, but human safety data are limited and a few risks have been reported.

Excessive chaga intake has been linked to two cases of kidney failure and one case of acute nephropathy, which the data attributes to its high oxalate content.

Side effects, ingredient by ingredient Chaga

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?
  • 2 of the 2 matched ingredients can interact with medications — Beta-glucans, 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: 494 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.

Double-check with your doctor or pharmacist if you take blood thinners (anticoagulants) or antiplatelet drugs, which are rated Moderate for chaga extract. Antihypertensive drugs, antidiabetes drugs, and immunosuppressants are also rated Moderate.

No interactions are documented for polyphenols because we could not check them.

Organic Chaga Mushroom by Dr. Mercola: Common Questions

Does Organic Chaga Mushroom by Dr. Mercola interact with any medications?
Yes. Based on its ingredients, Organic Chaga Mushroom has a known interaction with 494 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Chaga Mushroom 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.
Is Dr. Mercola Organic Chaga Mushroom safe during pregnancy?
The safety data advises against chaga during pregnancy because there is not enough safety information. We do not have pregnancy data on file for beta-glucan, so there is not enough information to know either way for that ingredient. Please talk with your doctor or pharmacist for advice about your situation.
Can I take this while breastfeeding?
Chaga is rated to be avoided while breastfeeding because the safety information is not sufficient. For beta-glucan, the data advises caution because there is little research on supplement doses during breastfeeding. Please talk with your own doctor or pharmacist before deciding.
Does chaga work for COVID-19 or diabetes?
The data rates the evidence for chaga in COVID-19 and diabetes as Insufficient Reliable Evidence To Rate. That means there is not enough reliable evidence to judge whether it works for these uses.
Does beta-glucan help with cholesterol?
The data rates beta-glucan as Likely Effective for dyslipidemia, which covers abnormal blood fats. It is also rated Likely Effective for coronary heart disease. Talk with your doctor about whether it fits your own health needs.
Are there kidney risks with chaga?
Excessive chaga consumption has been linked to two cases of kidney failure and one case of acute nephropathy in the data. These are attributed to chaga's high oxalate content. The risk is tied to excessive intake.
