Coryza Forte®, a blend of nutrients in capsule form, provides nutritional support for the immune system, particularly in the upper respiratory tract. Numerous scientific investigators have demonstrated the relationship between nutrients and components of the immune system such as T and B lymphocytes, immunoglobulins and the energy and chemistry of producing antibodies. Specific nutrients needed by the immune system and natural phytochemicals extracted from plants, such as those used in the Coryza Forte® formula, support the number and strength of cells in the immune system army.
