HelloPharmacist Scorecard of Chaga 500 mg by Aloha Medicinals

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.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (500 mg) without saying how much of each component you get.

Chaga 500 mg contains one active ingredient: Inonotus obliquus, a fungus that grows on birch trees and is used in traditional medicine. The product includes a vegetarian capsule and organic white milo as inactive ingredients.

Does it work?

Insufficient 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
Insufficient

There isn't enough reliable clinical evidence to rate this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: immunity, cardiovascular, liver and blood sugar support.
  • We looked for evidence on: Cardiovascular disease (CVD), Diabetes, Immune function, Cholesterol, Liver health.
  • The closest evidence on file: Chaga is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD) (Natural Medicines).
  • Also on file: Chaga is rated "Insufficient Reliable Evidence To Rate" for Diabetes.

The evidence we hold doesn't establish chaga's effectiveness for cardiovascular disease, diabetes, or COVID-19 — we have insufficient reliable evidence to rate it for any of those uses. If you're considering chaga for a specific health goal, talk with your doctor about what the data 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. There have been two reported cases of kidney failure and one case of acute kidney damage (acute nephropathy) linked to heavy chaga use — chaga contains high concentrations of oxalate, which is a concern for kidney health.

Pregnant and breastfeeding people should avoid it because there isn't enough safety information to know either way.

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 (like warfarin or aspirin), immunosuppressants, or diabetes medications, double-check with your doctor or pharmacist before adding chaga. The risk of bleeding and low blood sugar, and possible interference with immune-suppressing therapy, warrant a conversation beforehand.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with insufficient evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Chaga may be of interest if you're exploring traditional herbal use, but the science on whether it actually works for common conditions isn't established. If you take blood thinners, immunosuppressants, or diabetes drugs, check with your doctor or pharmacist before starting it.

Kidney health and pregnancy or breastfeeding status also matter — talk it over with your own healthcare provider first.
