HelloPharmacist Scorecard of Immune Matters by Bricker Labs

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 Aug 6, 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.

Immune Matters contains a single active ingredient: larch arabinogalactan, a soluble fiber derived from larch trees. It's included here as an immune-support supplement.

The tablet also contains several inactive ingredients — microcrystalline cellulose, dicalcium phosphate, tricalcium phosphate, stearic acid, silicon dioxide, magnesium stearate, and an aqueous clear coat — which serve as binders, fillers, and coating.

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 Larch Arabinogalactan's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supports natural immune function.
  • We looked for evidence on: Common cold, Immune response, Infection resistance, Respiratory health.
  • The closest evidence on file: Larch Arabinogalactan is rated "Insufficient Reliable Evidence To Rate" for Common cold (Natural Medicines).

The evidence for larch arabinogalactan isn't established in the data we hold. Studies on its use for common cold and high cholesterol show insufficient reliable evidence to rate it as effective for those purposes.

If you're considering this product for either of those reasons, talk it over with your doctor about whether the evidence supports it for your situation.

The evidence, ingredient by ingredient Larch Arabinogalactan

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.

Larch arabinogalactan is generally well tolerated as a fiber. Some people experience bloating and flatulence when they take it orally.

That said, high-quality long-term safety data are limited, and there isn't enough safety information available for us to advise on use during pregnancy or breastfeeding — talk with your doctor or pharmacist about whether it's right for you in those situations.

Side effects, ingredient by ingredient Larch Arabinogalactan

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 — Larch Arabinogalactan.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 121 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.

If you take an immunosuppressant drug — including azathioprine, cyclosporine, mycophenolate, tacrolimus, or similar medications used after transplants or for autoimmune diseases — check with your doctor or pharmacist before taking this supplement, as larch arabinogalactan may interfere with how those drugs work.

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.

Immune Matters is a single-ingredient supplement that's generally well tolerated as a fiber but lacks strong evidence for the immune or cholesterol benefits it implies. The main concern is immunosuppressant medications — if you take one, check with your doctor or pharmacist before starting this product.

For everyone else, the biggest practical side effect is likely bloating or gas.

Immune Matters by Bricker Labs: Common Questions

Does Immune Matters by Bricker Labs interact with any medications?
Yes. Based on its ingredients, Immune Matters has a known interaction with 121 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Immune Matters 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.
Will this help prevent colds or boost my immune system?
The evidence isn't strong enough to say yes or no. Studies on larch arabinogalactan for colds show insufficient reliable evidence to rate it as effective. Talk with your doctor if you're looking for proven cold prevention or immune support.
Can I take this if I have high cholesterol?
The data we hold doesn't show enough reliable evidence that larch arabinogalactan helps with high cholesterol. Check with your doctor about whether this supplement makes sense alongside your current cholesterol plan.
What are the side effects?
Most people tolerate it well. The main side effect is bloating and flatulence — gas and digestive discomfort — which some people experience when they take it. Long-term safety data are limited.
Is it safe to use during pregnancy or breastfeeding?
We don't have enough safety information to say one way or the other. Talk with your doctor or pharmacist — they can help you decide whether it's right for you during pregnancy or while breastfeeding.
What's larch arabinogalactan and why is it in here?
It's a soluble fiber from larch trees, included here as an immune-support ingredient. But keep in mind the evidence for its immune benefits isn't established in the data we hold.
