What else affects it

Beyond other supplements
!
High sugar diet

High sugar intake undermines blood sugar benefits

Excess glucose overwhelms metabolic improvements

How it works

  • Beta-glucans improve insulin sensitivity and glucose metabolism
  • D-fraction activates natural killer cells and immune response
  • Polysaccharides modulate inflammatory pathways
  • May inhibit alpha-glucosidase reducing glucose absorption
  • Supports pancreatic beta cell function
  • Enhances macrophage and dendritic cell activity

Key findings

what the evidence supports
  • Good evidence for blood sugar control and diabetes support
  • Moderate evidence for immune enhancement
  • Generally safe but monitor blood glucose with diabetes medications
  • D-fraction extract has strongest research backing
