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.

Larix Powder is a single-ingredient supplement containing larch arabinogalactan, a fiber derived from larch tree wood. It's used in wellness to support immune function and overall digestive health.

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 function and gut health support.
  • We looked for evidence on: Common cold, Immune function, Gut health, Prebiotic support.
  • 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 cholesterol don't show enough reliable evidence to make a firm claim 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, though long-term safety data of high quality are limited. Some people experience bloating and flatulence when taking it.

The safety data available aren't extensive enough for us to say it's clearly safe in all situations — talk with your doctor or pharmacist before starting, especially if you have any health conditions or take medications.

  • 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.

Immunosuppressant medications — drugs that weaken your immune system after transplant or for autoimmune disease — are the main class to watch. Examples include cyclosporine, tacrolimus, azathioprine, and mycophenolate.

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.
What is larch arabinogalactan?

The product facts don't give us enough information on safety during pregnancy or lactation. Talk with your doctor or midwife before using it if you're pregnant or nursing.
Will this help with my cold?
The evidence we have isn't strong enough to say whether it works for colds. If you want to try it, that's a conversation to have with your pharmacist or doctor.
