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.
What’s inside
Full disclosure
This product contains one active ingredient: beta-glucan derived from a Nordic source. Beta-glucan is a type of soluble fiber found naturally in foods like oats and mushrooms.
The capsule also contains several inactive ingredients — gelatin, sucrose fatty acid ester, silicon dioxide, and water — that help deliver the beta-glucan.
Does it work?
Strong evidence
The evidence supports beta-glucan for managing cholesterol levels (dyslipidemia) and supporting heart health. It's rated Likely Effective for both lowering cholesterol and reducing the risk of coronary heart disease.
The research behind these ratings is solid enough that if heart health or cholesterol control is your goal, this ingredient has real science behind it.
How safe is it?
Well-documented data
Beta-glucans from food sources are generally well tolerated by most people. However, concentrated supplements like this one lack the long-term safety data we have for food amounts, so caution is advised with regular use.
During breastfeeding, there isn't enough research on supplement doses to know either way, so talk with your doctor or pharmacist for personalized advice. When taken orally, adverse effects are rare; topical formulations have occasionally caused mild, self-limiting skin reactions in a small number of trial participants.
Meds to double-check
Moderate interaction found
Before you start, check whether you take any blood pressure medications (antihypertensives) or drugs that suppress your immune system (immunosuppressants). Beta-glucans may lower blood pressure further and could theoretically interfere with immune-suppressing therapy.
Use the search tool on this page to verify your exact medications.
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.
If you're looking to support heart health or manage cholesterol, beta-glucan is backed by solid evidence. Just double-check with your pharmacist if you take blood pressure medication or any drug that suppresses your immune system — the product may amplify or interfere with how those work.
If you're breastfeeding, ask your doctor or pharmacist whether this supplement is right for you.

Norwegian Beta 1,3/1,6 Glucan by Flora Drug Interactions
HelloPharmacist Interaction Report
Norwegian Beta 1,3/1,6 Glucan from Flora contains a single active ingredient, beta-glucan, which does interact with certain medications.
The most serious concern is with drugs that lower blood pressure (antihypertensives). Beta-glucans may lower your blood pressure on their own, so taking them alongside blood pressure medications could theoretically increase the risk of blood pressure dropping too low (hypotension).
Read the full breakdown — every affected drug type, severity by severity
The other documented interaction is with immunosuppressants (medications that calm down your immune system). Beta-glucans appear to have immune-stimulating effects, which could theoretically interfere with how these drugs work.
Both interactions are rated Moderate in severity. Altogether, these interactions span 287 individual medications.
If you take blood pressure meds or any immunosuppressant, check your exact medications with the tool on this page before starting this supplement.

For each ingredient in Norwegian Beta 1,3/1,6 Glucan with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Dietary Fiber
Carbamazepine (Tegretol)
Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.
Lithium
Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.
Metformin (Glucophage)
Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.
Olanzapine (Zyprexa)
Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.
Digoxin (Lanoxin)
Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.
Ethinyl Estradiol
Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.
Oral Drugs
Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.
Beta 1,3/1,6 Glucan
Antihypertensive Drugs
Theoretically, taking beta-glucans with antihypertensive drugs might increase the risk of hypotension.
Clinical research shows that taking beta-glucans may reduce systolic and diastolic blood pressure in some hypertensive individuals.
Immunosuppressants
Theoretically, beta-glucans might interfere with immunosuppressive therapy.
Some clinical research shows that beta-glucans have immunostimulant effects.
