Reishi mushroom has been treasured for centuries as a Chinese folk medicine and health tonic, and modern science is beginning to identify what makes it so valuable. Some of the key components are called polysaccharides and Nature's Way Reishi Mushroom is standardized to 10% polysaccharides in every serving. These active ingredients have many potential health benefits, especially in improving immune response.Beta-glucans are a type of polysaccharide in Reishi with the ability to activate the immune system without the risk of over-stimulating the immune system like some pharmaceutical drugs. Beta-glucans are currently being studied for their potential to lower elevated bad cholesterol levels, assist wound healing and prevent infections. Besides immune support, Reishi mushroom may also help lower blood pressure and blood sugar levels. With more and more benefits being discovered, protecting your immune system is only the start of what Nature's Way Reishi Mushroom will do for you.
