Acute Immune formula is a combination of immune enhancing vitamins, minerals and botanical medicines. These ingredients have been clinically shown to effectively strengthen and support the immune system. Beta Glucan, Echinacea purpurea, and DMG support T-cell activity (the body's first line of defense) and assist in strengthening immunity. Oregano, an herb with natural antiviral and antibacterial properties, was found to kill all 30 germs it was tested against in a study at Cornell University. Acute Immune contains a blend of six organic immune-specific mushrooms that have been clinically shown to be highly effective in immunomodulation and increased immune function.
