HelloPharmacist Scorecard of Norwegian Beta 1,3/1,6 Glucan by Flora

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 11, 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: beta-glucans sourced from Norway. Beta-glucans are a type of fiber found naturally in certain foods and fungi; they're extracted here in concentrated form.

The capsule itself is made from gelatin, and the other ingredients are excipients — sucrose fatty acid ester, silicon dioxide, and water — that help hold the capsule together.

Does it work?

Strong 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

This product doesn't appear to be marketed for a specific use, so we graded Beta-glucans's overall clinical evidence instead.

Strong

Strong clinical evidence supports Beta-glucans for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Natural Medicines).
  • On file: Dyslipidemia — rated "Likely Effective" (Natural Medicines).

Beta-glucans in this form are likely effective for two conditions: improving cholesterol levels (dyslipidemia) and supporting heart health in coronary heart disease. That said, this single-ingredient product gives you just one tool, and heart health usually needs a fuller picture — talk with your doctor about whether it fits into your complete plan.

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 sources are generally well tolerated. When you take them as a concentrated supplement like this one, the safety data isn't as solid as it is for food amounts, so caution is reasonable.

Topical beta-glucan products have caused mild, self-limiting skin reactions in some people, though you're taking this orally. One person in a high-dose trial showed temporary liver enzyme elevations; routine use at typical doses hasn't shown the same pattern.

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 (antihypertensives) and any immunosuppressant drugs before starting this product. Beta-glucans can lower blood pressure and may interfere with immune-suppressing medications — both rated Moderate severity interactions.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with cholesterol and heart health if that's what you're aiming for. If you take blood pressure medications or any drug that suppresses your immune system, check with your pharmacist first — beta-glucans could affect how those work.

Talk to your pharmacist or doctor before you start, especially if you have heart or liver concerns.

Yes. Based on its ingredients, Norwegian Beta 1,3/1,6 Glucan 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?
Norwegian Beta 1,3/1,6 Glucan 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 actually help with cholesterol?
Yes — beta-glucans are likely effective for improving cholesterol levels and supporting heart health in coronary heart disease. That said, it's one piece; your doctor can tell you if it fits your full plan.
Is it safe to take if I'm breastfeeding?
There isn't enough research on concentrated supplement doses during breastfeeding to know either way. Talk with your pharmacist or doctor for advice tailored to your situation.
Will this mess with my blood pressure pills?
Possibly — beta-glucans lower blood pressure on their own, so taking them together with your medication could drop it too low. Check with your pharmacist before you start.

Beta-glucan is a type of fiber found naturally in certain foods and fungi. Here it's extracted and concentrated into a supplement form to boost the dose you'd normally get from eating.
