HelloPharmacist Scorecard of Chaga Mushroom Powder by TerraVita Premium Collection

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

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 a single active ingredient: chaga mushroom powder. Chaga is a fungus that grows on birch trees and is commonly used in teas and food preparations.

There are no inactive fillers or other ingredients listed.

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 Chaga product and its label doesn't state a use — see Chaga'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.

The evidence we hold doesn't establish that chaga is effective for cardiovascular disease, diabetes, or coronavirus disease. The data rates all these uses as having insufficient reliable evidence, meaning we don't yet know whether it works for these purposes.

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. There have been rare reports of serious kidney problems — two cases of kidney failure and one case of acute kidney injury — linked to heavy chaga use, because chaga contains high concentrations of oxalate, a compound that can affect kidneys.

The safety data advise against using chaga during pregnancy and while breastfeeding due to insufficient 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 any of these, check with your doctor or pharmacist before starting: blood thinners or antiplatelet drugs (moderate risk of increased bleeding), immunosuppressants (moderate risk of interference with your transplant or autoimmune therapy), or diabetes medications (moderate risk of low blood sugar). No interactions are documented for any other drugs we checked.

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 mushroom powder might appeal to someone exploring traditional remedies, but it's not established to work for cardiovascular or metabolic conditions. If you take blood thinners, diabetes medications, or drugs that suppress your immune system, clear this with your doctor or pharmacist first — the interactions are theoretical but documented.

Because of kidney concerns and limited safety data, pregnant and breastfeeding people should avoid it.

Chaga Mushroom Powder by TerraVita Premium Collection: Common Questions

Does Chaga Mushroom Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Chaga Mushroom Powder 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 Mushroom Powder 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 chaga safe during pregnancy?
No — there isn't enough safety information, and the data advise against it during pregnancy. Talk with your doctor or pharmacist if you're pregnant or planning to be.
Is it safe if I'm breastfeeding?
No — there isn't enough safety information, and the data advise against it while breastfeeding. Check with your doctor or pharmacist for personalized advice.
Can chaga hurt my kidneys?
There's a rare risk. Chaga contains high levels of oxalate, and there have been a few reports of serious kidney problems, including kidney failure, linked to heavy use. If you have kidney disease or a history of kidney stones, talk with your doctor first.
Does chaga actually work for blood sugar or heart health?
The evidence we hold doesn't establish that it works for either. Both uses are rated as having insufficient reliable evidence, so we don't yet know whether chaga helps.
How much chaga is too much?
The facts don't specify a safe dosing range. Because kidney problems have been reported with excessive use, talk with your doctor or pharmacist about how much is right for you.
