Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Beta-glucans and Dulaglutide in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first.

Beta-glucans and Dulaglutide

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Dulaglutide and Beta-glucans in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Beta-glucans safety at a glance

Beta-glucans overall Generally safe Beta-glucans from food sources are generally well tolerated by most people.
Pregnancy Use caution Beta-glucans in normal food amounts are likely fine, but concentrated supplements lack safety data, so use caution.
Breastfeeding Use caution There is little research on supplement doses during breastfeeding, so caution is advised.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Dulaglutide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Dulaglutide is filed under a single classification — antidiabetes drugs. Beta-glucans has documented interactions with 2 drug classes — the most serious being antihypertensive drugs (moderate) and immunosuppressants (moderate) — and none of Dulaglutide’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What to actually watch for

What Beta-glucans Itself Has Been Linked To

This is not an interaction — nothing below involves Dulaglutide. It is the side-effect record for Beta-glucans on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Beta-glucans, this list is the first place to look.

  • A skin rash Additional detail

    “Topically, a specific beta-glucans cream (Imunoglukan P4H, PLEURAN s.r.o.) has been reported to cause skin reactions and contact dermatitis in one clinical trial. These reactions occurred in 27% of patients; reactions were mild and self-limiting in 12% of patients.”

Everything above comes from the Natural Medicines adverse-effect record for Beta-glucans — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Dulaglutide’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Dulaglutide column appears here.

Overlapping uses

What Dulaglutide Is Prescribed For, and What Beta-glucans Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Dulaglutide is a prescription medicine with approved uses on its FDA label. Beta-glucans is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Dulaglutide is prescribed for: Trulicity (dulaglutide) injection is used alongside diet and exercise to improve blood sugar control in adults and children 10 years and older with type 2 diabetes mellitus. It is not for type 1 diabetes. Trulicity is also used in adults with type 2 diabetes who have established cardiovascular disease or multiple cardiovascular risk factors to lower the risk of major heart events — specifically cardiovascular death, non-fatal heart attack, or non-fatal stroke.

Beta-glucans has been studied for:

  • Diabetes studied, not established Beta-glucans has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Beta-glucans for diabetes

    Small clinical studies in children and adults with type 1 diabetes suggest that beta-glucans do not improve blood glucose levels. It is unclear if oral beta-glucans are beneficial for patients with type 2 diabetes.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Dulaglutide on your own; if you are taking Beta-glucans for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

See Every Supplement That Interacts With Dulaglutide

This page covers Beta-glucans only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Dulaglutide page lists 239 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate), Agaricus Mushroom (moderate) and Agmatine (moderate).

By severity: 1 major · 208 moderate · 30 minor.

From our pharmacist’s overview on the Dulaglutide page

“Because dulaglutide (Trulicity) already lowers blood sugar in people with type 2 diabetes, nearly every entry on this page deserves genuine respect, and one demands it outright. Almost all of these supplements pull glucose in one direction or the other, so the danger that matters most is hypoglycemia, blood sugar dropping too low.”

About Beta-glucans

What is Beta-glucans?

  • High cholesterol
  • Heart health
  • Immune support
  • Blood sugar control
  • Wound care (topical)

Beta-glucans are natural fibers found in oats, barley, mushrooms, and yeast. The strongest evidence supports the oat and barley types for modestly lowering cholesterol and blood sugar, while immune-related claims from yeast and mushroom sources are far less proven. They are generally well tolerated, but check with your pharmacist before starting any supplement.

Cell walls of yeast, mushrooms, oats, and barley · Capsules, tablets, powders, oat or barley foods, topical creams

An interaction check asks whether these two react with each other — it does not ask whether Beta-glucans is a good idea for someone in your situation. Here is what our Beta-glucans record says about it on its own.

Beta-glucans: dosing

There is no single "official" supplement dose for all beta-glucans, and the right amount depends on the source and the product. For cholesterol benefits from oats and barley, health authorities often refer to a daily amount of beta-glucan as part of the diet, which can be reached by eating oat and barley foods or using a labeled supplement.Yeast and mushroom beta-glucan supplements vary widely, and a clearly proven dose has not been established.

Taking Beta-glucans and Dulaglutide Together: Common Questions

Is it safe to take Beta-glucans with Dulaglutide?
We do not list a known interaction between Beta-glucans and Dulaglutide. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Are Beta-glucans and Dulaglutide used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Beta-glucans in each. That is a conversation for your prescriber, especially if Dulaglutide is being adjusted to a target.
How was the Beta-glucans and Dulaglutide combination checked?
Interactions in our licensed database are recorded against drug classes. Dulaglutide is filed under 1 classification, and Beta-glucans has documented interactions with 2 drug classes — none of Dulaglutide's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Beta-glucans interact with any other medications?
Yes. Beta-glucans has 293 documented drug interactions in our database — Dulaglutide is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Dulaglutide interact with any supplements?
Yes. Dulaglutide has documented interactions with 239 supplements in our database — Beta-glucans is not one of them. The Dulaglutide interaction page linked on this page lists every one, ranked by severity.
