Ultra Beta-Glucan with Maitake Extract — Supports Normal Immune Cell Activity*
Our Ultra Beta-Glucan with Maitake combines well-researched β-1,3/1,6-glucan from Saccharomyces cerevisiae with Maitake (Grifola frondosa) polysaccharide fractions in veggie capsules to support balanced immune modulation, promote innate readiness and surveillance, help maintain macrophage and NK-cell activity, support cytokine balance, provide foundational immune wellness, promote coordination between innate and adaptive responses, help maintain immune cell function, support healthy inflammatory signaling, promote overall immune vitality, help maintain comfort during seasonal challenges, and support comprehensive immune health* — while respecting standardized, synergistic sourcing. Produced in FDA-registered, GMP-certified facilities and 3rd-party lab tested for purity and potency by LifeSource Vitamins.
