HelloPharmacist Scorecard of BetaRight Beta Glucan 250 mg by Swanson

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 1, 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 one active ingredient: BetaRight 3-6, a beta-glucan derived from yeast cell walls. Beta-glucans are natural compounds that your immune system and heart health rely on.

The capsule itself is filled with gelatin and microcrystalline cellulose (a common filler), which are inactive ingredients.

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 system nourishment and cellular defense.
  • We looked for evidence on: Exercise-induced respiratory infections, Lower respiratory tract infections, Upper respiratory tract infection (URTI), Critical illness (trauma), Wound healing, Immune function — and 1 related terms.
  • The closest evidence on file: Beta-glucans is rated "Insufficient Reliable Evidence To Rate" for Lower respiratory tract infections (Natural Medicines).
  • Also on file: Beta-glucans is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced respiratory infections, Wound healing, Critical illness (trauma), Upper respiratory tract infection (URTI).

Beta-glucans in this product are rated likely effective for two key uses: lowering cholesterol (dyslipidemia) and supporting heart health in coronary heart disease. That said, real-world results vary — the evidence shows the benefit is there for many people, but not everyone will see the same outcome.

The evidence, ingredient by ingredient 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 are generally well tolerated. With concentrated supplements like this one, though, safety data is limited — so use caution and start at a low dose if you're new to it.

In one clinical trial, a child developed temporary liver enzyme elevations early on. Topical beta-glucans cream caused mild skin reactions in some users, though that doesn't apply to oral capsules.

We don't have enough safety data on supplement doses during breastfeeding, so talk it over with your doctor or pharmacist first.

Side effects, ingredient by ingredient Beta-glucans

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 — 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 blood pressure medications and any drugs that suppress your immune system before taking this product. Beta-glucans may lower blood pressure further and might interfere with immune-suppressing drugs' effectiveness.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

BetaRight may help with cholesterol and heart health if you don't take blood pressure or immune-suppressing medications. If you're on either of those, check with your doctor or pharmacist before adding this in — the interactions are real.

Start low and watch how you feel, and flag any new symptoms with your healthcare provider.

BetaRight Beta Glucan 250 mg by Swanson: Common Questions

Does BetaRight Beta Glucan 250 mg by Swanson interact with any medications?
Yes. Based on its ingredients, BetaRight Beta Glucan 250 mg has a known interaction with 293 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
BetaRight Beta Glucan 250 mg 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 this really help lower cholesterol?
Yes — beta-glucans are rated likely effective for dyslipidemia (high cholesterol). That doesn't mean it works for everyone, but the research backs it up for many people.
What are beta-glucans, anyway?
They're natural compounds found mostly in yeast and fungi that help your immune system and heart. BetaRight 3-6 is a purified form extracted from yeast cell walls.
Can I take this while breastfeeding?
We don't have enough data on supplement doses during breastfeeding to say either way. Talk with your doctor or pharmacist about whether it's right for you right now.
What are the inactive ingredients in this capsule?
Gelatin and microcrystalline cellulose — a capsule shell and filler. Both are standard and inert.
Could this interact with my blood pressure meds?
Yes — beta-glucans can lower blood pressure on their own, so taking them with your medication might drop it too far. Check your specific medications with your doctor or pharmacist first.
Are there any common side effects?
Oral beta-glucans are generally well tolerated, and most people don't report problems. Topical creams have caused mild, short-lived skin reactions in some users, but that doesn't apply to this capsule.
