HelloPharmacist Scorecard of Chaga by HealthForce SuperFoods

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.

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.
  • “Chaga (Inonotus obliquus) sclerotium extract” is listed as a grouped ingredient — the label gives one combined amount (2,000 mg) without saying how much of each component you get.

This product contains one active ingredient: beta-glucans extracted from chaga mushroom. Beta-glucans are polysaccharides — basically long-chain sugars — from the fungus Inonotus obliquus, and they're the compounds thought to be responsible for chaga's effects on heart health and cholesterol.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Beta-glucans's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: immune support and antioxidant wellness.
  • We looked for evidence on: Aging, Chronic fatigue syndrome (CFS), Exercise-induced respiratory infections, Lower respiratory tract infections, Upper respiratory tract infection (URTI), Wound healing — and 3 related terms.
  • The closest evidence on file: Beta-glucans is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS) (Natural Medicines).
  • Also on file: Beta-glucans is rated "Insufficient Reliable Evidence To Rate" for Upper respiratory tract infection (URTI), Exercise-induced respiratory infections, Lower respiratory tract infections, Wound healing, and more.

Beta-glucans in chaga are rated Likely Effective for two things: lowering cholesterol (dyslipidemia) and supporting heart health in coronary heart disease. The evidence behind these ratings comes from clinical research showing real effects on cholesterol and blood vessel function.

The evidence, ingredient by ingredient Chaga Beta-glucans

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.

Beta-glucans from food sources are generally well tolerated. Concentrated supplements, though, haven't been studied as thoroughly, so it's wise to be cautious with high doses.

Side effects from the supplement form are uncommon, though very rarely people have experienced mild skin reactions if applied topically. There's not much research on supplement doses during breastfeeding, so talk with your doctor or pharmacist if you're nursing.

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 — Beta-glucans.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 293 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 your medications against this product if you take blood pressure drugs (antihypertensives) or immunosuppressants — both have Moderate-severity interactions documented with the beta-glucans in chaga. Use the medication checker on this page with your exact prescriptions before you start.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you're managing cholesterol or heart disease and aren't on blood pressure medication or immunosuppressants, chaga may be worth discussing with your pharmacist. Anyone taking drugs to control blood pressure or suppress their immune system should check their specific medications first — the interactions are real enough to warrant caution.

Formula

Chaga (Inonotus obliquus), known as "The King of Medicinal Mushrooms," has long been used in folk medicine in the Eastern Hemisphere, especially in Siberia, where legends tell of an amazing birch fungus (or mycelium mass, known as a sclarotia) with miraculous health properties. Records dating back to 1000 B.C. show the use of chaga to balance the body's life force, or "chi", in Traditional Chinese Medicine. Chaga offers an abundance of antioxidants for skin, hair, and nail health, as well as overall support for increased immunity and vitality. Chaga has a mild, earthy, slightly bitter flavor. Our chaga is wildcrafted and hot water extracted for greatest bioavailabiltiy. Chaga can be added to your favorite smoothie, fresh juice, coffee, or tea.

Chaga by HealthForce SuperFoods: Common Questions

Does Chaga by HealthForce SuperFoods interact with any medications?
Yes. Based on its ingredients, Chaga 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?
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.
Does chaga actually help with cholesterol?
Yes — the beta-glucans in chaga are rated Likely Effective for lowering cholesterol (dyslipidemia). Clinical research backs this up, so if that's your goal, it's one of the better-supported uses.
Is chaga safe if I'm not on medications?
Beta-glucans from food sources are generally well tolerated. The supplement form hasn't been studied as much as food forms, so use some caution with high doses. For most people without the specific drug interactions mentioned, it should be fine — but it's still worth a quick conversation with your pharmacist.
Can I take chaga while breastfeeding?
There isn't enough research on supplement doses during breastfeeding to say either way. Talk with your doctor or pharmacist to figure out what's right for you and your baby.
What's in this powder besides the active ingredient?
Just the beta-glucans from chaga — no inactive fillers or other ingredients are listed.
Could chaga interfere with my blood pressure medication?
Possibly. Beta-glucans can lower blood pressure on their own, so taking them with blood pressure drugs might push your pressure too low. Check your exact medications using the tool on this page before starting.
