Congaplex contains vitamins A and C, calcium, and magnesium to help support immune system function. Vitamin A plays an important role in a healthy immune system by facilitating the development of type 1 and type 2 helper T cells as well as contributing to the function of both T cells and B cells.Vitamin C enhances the healthy function of the immune system by supporting the maturation of T cells. Additionally, vitamin C stimulates the functions of leukocytes and is important in natural killer (NK) cell activity. Vitamin C also assists the maintenance and regeneration of cells. Research by Standard Process scientists concluded that T lymphocyte cells treated with Congaplex showed statistically significant changes in cytokine levels and an increase in T cell signaling in a dose-dependent manner. Congaplex contains Cytosol extract from the bovine thymus gland to support the healthy function of human thymus gland. T cells are produced in the thymus gland and are very important for a healthy immune system response. Cells require a steady supply of nucleotides to properly build RNA molecules to perform important functions such as protein synthesis and message delivery in cells. Research has indicated that it is important to have nucleotides readily available to tissues that are experiencing stress. It is thought that during these times of stress the cells require more raw materials, such as nucleotides, to maintain health. - Helps support healthy immune system function and thymus gland - Provides ingredients with antioxidant activity - Contains ribonucleic acid, which the body uses to build new cells - Contains a combination of key ingredients from Cataplex A-C, Thymex, Calcium Lactate, and Ribonucleic Acid (RNA) - High in antioxidant vitamin C
