HelloPharmacist Scorecard of Arabinogalactan Larch Tree Vital Extracts 300 mg by Solaray

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

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.
  • “Arabinogalactan” is listed as a grouped ingredient — the label gives one combined amount (300 mg) without saying how much of each component you get.

This supplement contains one active ingredient: larch arabinogalactan, a fiber derived from larch trees. The capsule also contains inactive ingredients — cellulose, cassava flour, rice extract blend, and silica — which are fillers and binders that give the product its form.

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: Immune system support and digestion.
  • We looked for evidence on: Common cold, Gut health, Prebiotic function, Infection prevention.
  • The closest evidence on file: Larch Arabinogalactan is rated "Insufficient Reliable Evidence To Rate" for Common cold (Natural Medicines).

We don't have reliable evidence that larch arabinogalactan works for common cold or high cholesterol (hyperlipidemia). The data shows insufficient evidence to rate it for either condition.

That doesn't mean it doesn't work — just that the evidence we hold isn't established enough to say one way or the other.

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 do experience bloating and flatulence.

Long-term safety data are limited, and there isn't enough information about use during pregnancy or breastfeeding — your doctor or pharmacist should weigh in if you're pregnant, nursing, or planning to be.

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 immunosuppressant medications — including cyclosporine, tacrolimus, mycophenolate, basiliximab, daclizumab, muromonab-CD3, or azathioprine — check with your pharmacist before starting this product. Larch arabinogalactan may interfere with how these drugs suppress your immune system.
