Respiratory Concerns

Respiratory infections and chronic airway inflammation remain leading causes of illness worldwide. Research shows that beta glucan, a natural immune-modulating fiber, supports lung defense by enhancing mucosal immunity and balancing inflammatory pathways. This dual action helps the body better resist and recover from respiratory challenges.
