INSIGHT

Unique Immune Receptors Targeted

  • Beta-glucans bind unique immune receptors (Complement receptor 3 and Dectin-1) to modulate immunity.
  • This drives NK cell and macrophage activation distinct from other natural products.

Immune Aging Drives Biological Aging

  • Immunosenescence (aging of immune cells) may be a major driver of biological aging.
  • Supporting immune function like with beta-glucan could indirectly improve longevity and disease outcomes.

Gut Effects: Prebiotic And Postbiotic

  • Beta-glucan acts as a prebiotic feeding Lactobacillus and Bifidobacterium and raises short-chain fatty acids.
  • Increased butyrate supports gut barrier integrity and lowers systemic endotoxin.
