Tri-Mune combines three antioxidants to help stimulate healthy immune system response. Tri-Mune includes Ester-C, Vitamin E and Beta Glucan. Studies show that Tri-Mune is absorbed twice as fast as Vitamin C and blood levels up to 4 times greater. It protects cells from free radical damage and supports brain function with Vitamin E. Beta Glucans have proven to be part of the first line of defense in immune response. Feed 2 oz. daily during high levels of stress; 1 oz. daily for maintenance. Meal.
