Ingredients-101-ARABINOGALACTAN

This is part of our ongoing series helping consumers better understand chemicals, chemistry, and product formulations. We translate the science, bust the myths, and give you an honest assessment, so you can make informed choices for your family!

Ingredient:

Arabinogalactan

What it is:

Arabinogalactan (AG) is a polysaccharide (a chain of sugar molecules) found in a wide range of foods like carrots, radishes, wheat, Shiitake mushrooms, and coconuts, as well as plants like Echinacea purpurea and Thuja occidentalis. For commercial products, AG is most commonly sourced from Larch trees (which have a very high concentration of the substance) using an eco-friendly, hot water extraction process.

What it does:

Arabinogalactan is a relatively new darling in the world of nutraceuticals (it’s been “new” for the past 20 years), and a rich body of research shows the many benefits of Arabinogalactan:

  • Helps build a more responsive immune system
  • Supports monocyte production in the mononuclear portion of the immune system, one of the first lines of defense against foreign invaders
  • Decreases the incidence of common cold
  • Functions as a prebiotic and significantly enhances beneficial gut microflora, specifically increasing anaerobes such as Bifidobacteria and Lactobacillus, while decreasing harmful Clostridia
  • Increases short chain fatty acid (SCFA) production, decreases ammonia generation, and lowers the colon pH, which is thought to play a role in the protection against a variety of gastrointestinal diseases
  • Stimulates natural killer (NK) cell cytotoxicity which aids in fighting viruses and tumors

Why we use it:

It’s true: not all sugars are bad for you! Arabinogalactan is one of the key ingredients in both our Kid’s Immunity Boost and our Immunity Defense Health + Wellness products. Not only does it have amazing immune boosting powers, it’s also 100% water soluble and has a very mild taste, making it easy to digest and subtly flavor your child’s favorite food (yogurt, oatmeal, jelly sandwich, etc.), smoothie, or milk choice.

Why we’re featuring it today:

The U.S. Food and Drug Administration does not require supplement manufacturers to prove that their products do what they say they’re going to do. The more you know, the more you might question whether or not it’s worth it to invest your hard-earned money into these types of products – rightly so!

We appreciate that, so that’s why we (and our renowned team of expert Medical Advisors) do enormous amounts of research as we develop our products. We’re also vigilantly ensuring our formulas keep up with our ever-evolving scientific understanding of the human body.

We get our fair share of questions from people wondering what kind of evidence we have for our formulations and this blog series is one way we can share that with you. See the list of references below for a sampling of the peer-reviewed research conducted on arabinogalactan that have guided our decision-making.
