(Med-Vet Pharmaceuticals) Tri-Mune combines three antioxidants to help stimulate healthy immune system response. Tri-Mune contains 2500 mg Ester-C, 500 mg beta-glucan, and 2500 IU vitamin E per ounce. Ester-C is non-acidic; studies have indicated it's absorbed twice as fast as regular vitamin C with tissue and blood levels up to 4 times greater. Vitamin E protects cells from the damaging effects of free radicals and supports neurological function. Beta Glucans are shown to be immune response potentiators and modulators and are part of the first line of defense in immune response.
