Arabinogalactans are long, densely branched, high-molecular weight polysaccharides found in many plants, with the highest concentrations in larch trees. Larch arabinogalactan, specifically obtained from the western larch (Larix occidentalis) and eastern larch (Larix laricina), is approximately 98% arabinogalactan. This polysaccharide has a range of potential health benefits, including serving as a soluble, non-viscous fiber that ferments in the gut, potentially increasing beneficial gut bacteria like Lactobacillus. Additionally, larch arabinogalactan has been investigated for its possible role in drug delivery systems due to its water solubility and numerous hydroxyl groups, which may enhance the bioavailability of drugs like ibuprofen. Moreover, preliminary research suggests immunostimulatory effects, such as increased natural killer cell activity and enhanced immune response to certain vaccines.

The American elder (Sambucus canadensis) is a plant native to North America. It is a member of the Caprifoliaceae family and is commonly known as elderberry or simply 'elder'. It has large leaves and produces clusters of small, white, or cream-colored flowers. The plant's fruit is a dark blue/purple berry. American elder (Sambucus canadensis) and black elder (Sambucus nigra) are two different species of plants in the Sambucus genus. Both are used in traditional medicine and as food. They are claimed to have a variety of health benefits and are commonly used for their purported immune system-stimulating effects. However, black elder (Sambucus nigra) is far more commonly utilized in dietary supplements.

Maitake mushrooms, also known as Grifola frondosa or "hen of the woods," are a type of edible mushroom native to Japan and parts of China and North America. They have a distinctive, fan-shaped appearance and are often found growing at the base of trees. Maitake mushrooms are known for their flavor and texture, as well as their purported health benefits. They are high in antioxidants and may have anti-inflammatory, immune-boosting, and blood sugar-regulating effects. In traditional Japanese medicine, maitake mushrooms have been used to treat a variety of conditions, including high blood pressure and diabetes. Supplements containing maitake mushrooms often highlight the "D-fraction" of beta-glucan and a type of protein called "SX-fraction".
