What does a larch tree have to do with gut and immune health?
The larch is unusual among conifers: it’s deciduous and sheds its needles each fall. But that’s not the only thing that makes this tree remarkable. Its inner bark is a rich source of arabinogalactan, a soluble prebiotic fiber studied for its role in gut and immune health.
Arabinogalactan helps nourish beneficial gut bacteria and supports healthy immune function.* Larix makes this prebiotic fiber easy to add to your routine, with a mixable powder or convenient capsules.
What is arabinogalactan?
Larix is the botanical genus for larch trees. Eclectic Herb’s Larix products are made with arabinogalactan from Larix laricina.
Arabinogalactan is a complex plant carbohydrate, or polysaccharide. It’s soluble in water and resists digestion in the upper digestive tract. In the large intestine, gut microbes can ferment it—one reason it’s described as a prebiotic fiber.
Find Your Larix
Choose Larix Powder to mix into a drink or food, or Larix Capsules for a convenient, no-mixing option. Both provide larch arabinogalactan, a prebiotic fiber that supports healthy immune function and nourishes beneficial gut bacteria.*
Why does gut health matter for immune support?
The gut and immune system are closely connected. The gut is home to a diverse community of microorganisms, and researchers continue to study how that community interacts with immune function.
As a source of soluble prebiotic fiber, larch arabinogalactan helps nourish beneficial gut bacteria and supports digestive wellness.* Larix also supports healthy immune function.* Together, these features make it a distinctive choice for people looking to add prebiotic fiber and daily immune support to their routine.
Benefits of Larix (Arabinogalactan)
Larix offers immune support without intensity or overstimulation. Its benefits are rooted in how it interacts with the gut and immune system, making it suitable for both daily maintenance and short-term support. Here’s a closer look at how Larix works and why it’s widely trusted.
- Supports healthy immune function:Â Larix provides arabinogalactans that help the immune system respond appropriately to seasonal challenges. It supports immune readiness without overstimulation, making it suitable for daily use.
- Works where much of the immune system lives — the gut: A significant portion of the immune system is located in the gut. Larix acts as a soluble dietary fiber, supporting immune activity through the gut–immune connection rather than working only at the surface level.
- Effective for daily use and early intervention:Â Larix is commonly used throughout winter for ongoing immune maintenance. Many people also increase use at the first sign of seasonal stress to support a quicker, more efficient immune response.
- May help reduce how long seasonal symptoms linger:Â When used early, Larix supports immune communication and balance, which may help the body move through seasonal challenges more smoothly.
- Gentle enough for regular, long-term use:Â Larix arabinogalactans are classified by the FDA as a soluble dietary fiber, reflecting a strong safety profile and suitability for consistent use over time.
- Supports respiratory health during colder months:Â Traditionally used in winter, Larix helps support normal respiratory function when cold air, indoor environments, and seasonal exposures place extra demand on the lungs.
- Easy to use for the whole family: Water-soluble and nearly tasteless, Larix blends easily into soups, teas, juice, or water—making it simple to use daily, even with children.
- Pairs well with other immune support herbs: Larix works well alongside echinacea, elderberry, garlic, or ginger, serving as a steady foundation while other herbs are layered in as needed.
