The Active Ingredient Is: Arabinogalactan (ResistAid from Larix spp. heartwood)

Arabinogalactan is a soluble fibre and glyconutrient derived from the heartwood of the larch tree. This form is standardised to a specific content for human use and acts as a natural, plant-derived supplement ingredient.

This preparation uses ResistAid arabinogalactan from Larix species heartwood, a common source recognised for immune-supporting properties in glyconutrient applications.

What Does Arabinogalactan Do?

Arabinogalactan participates in normal immune function and acts as a soluble prebiotic fibre, supporting gut microbial balance and frontline immune responses according to research communications. It may also affect immune cells that patrol for irregular activity.

Dr. D’Adamo of the University studied arabinogalactan’s effects on immune activity, including natural killer cell function and T cell markers, supporting its role in immune health in adults.
