Larch arabinogalactan

Tier 2 — promising · Prebiotic · Immunity · Fibre

A soluble prebiotic fibre from larch trees that feeds beneficial gut bacteria and promotes butyrate production. Limited clinical studies suggest it may enhance immune function by increasing NK cell activity. Dissolves easily in water and is very well tolerated with minimal gas or bloating vs other prebiotic fibres. More human research is needed.

Dose: 4―30 g/day dissolved in water; well-tolerated prebiotic fibre; immune claims need more research
