HelloPharmacist Scorecard of Chaga by Om Mushroom Superfood

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 16, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 1 active ingredient.
  • “Certified Organic Mushroom Powder Blend” is a proprietary blend — the label gives one combined amount (2 Gram(s)) without saying how much of each component you get.

This product contains one active ingredient: chaga powder, a medicinal mushroom. The capsule also holds cellulose and oats as inactive ingredients (binders and fillers).

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: antioxidant support and immune defense.
  • We looked for evidence on: skin health, free radical damage, inflammation.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for chaga's effectiveness isn't established in the data we hold. We don't have reliable evidence to rate it for cardiovascular disease, diabetes, or COVID-19.

If you're considering chaga for any of these conditions, talk with your doctor about what the science actually 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 two cases of kidney failure and one case of acute kidney injury tied to very high chaga consumption — chaga contains high levels of oxalate, which can be hard on the kidneys.

Chaga is not recommended during pregnancy or breastfeeding because there isn't enough safety information.

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?
  • 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.

If you take blood thinners or antiplatelet drugs, diabetes medications, or immunosuppressants, talk with your doctor or pharmacist before starting chaga. These are the medication types most likely to interact with it.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure 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 mushroom supplements, but it's not proven to work for major health conditions. If you take blood thinners, diabetes drugs, or immune-suppressing medications, check with your doctor or pharmacist first.

Avoid it during pregnancy and breastfeeding, and watch your total intake to avoid kidney issues.

Chaga by Om Mushroom Superfood: Common Questions

Does Chaga by Om Mushroom Superfood interact with any medications?
Yes. Based on its ingredients, Chaga has a known interaction with 327 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Chaga 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 chaga if I'm pregnant or breastfeeding?
No. There isn't enough safety information about chaga during pregnancy or breastfeeding, so it's best to avoid it. Talk with your doctor if you want to use it during these times.
Does chaga actually work for heart health or blood sugar?
We don't have reliable evidence to say whether it does. The data we hold rates both cardiovascular health and diabetes support as insufficient evidence, so the science isn't there yet.
What's the risk with chaga and kidney health?
Chaga contains high levels of oxalate. There have been rare cases of kidney failure and acute kidney injury from very high consumption. If you have kidney concerns or a history of kidney stones, check with your doctor before taking it.
I take a blood thinner — is chaga safe for me?
Animal research suggests chaga might affect blood clotting, which is a concern with blood thinners. Talk with your doctor or pharmacist before starting chaga; they can tell you if it's okay for you.
