ImmBooster

Lewis Labs ImmBooster supplies a pure dose of the highest-quality beta glucan, professional-grade Glucan500™, to help you achieve optimal immune health, raise your energy levels and boost mood and vitality.

Beta glucan is thought to selectively enhance the activities of key immune cells such as macrophages without stimulating other immune cells called proinflammatory cytokines, which can cause damage by increasing levels of inflammation. As a natural immune system modulator and a biological response modifier, beta glucan is also thought to balance your immune system by blocking steps in the inflammatory and immune processes when the system is too active, promoting a healthy immune response. 
In studies, users of Glucan 500™ also reported statistically significant improvements in their wellbeing, including mood, energy levels and vitality. It is also taken to support healthy bone density.
