The thymus is the primary gland of the lymphatic system located just beneath the breastbone. The thymus is largest, relative to body weight, at the age of two. The gland is at its absolute largest at puberty. The peak production of thymic hormone secretion is around age one and begins to gradually decline until the age of 50–60 years, referred to as “thymic involution.” Chemotherapy, stress and trauma can also cause significant decline in thymus function.

Thymic Immune Factors is a synergistic formula that contains a full complement of herbal activators in addition to fresh, healthy thymus, lymph and spleen tissues. This combination is supportive for optimizing healthy immune function. The primary ingredient is tissue from the master organ of the system: the thymus gland. Also included is tissue from the lymph nodes and spleen. The immune system tissue extracts in this formula are raw, concentrated, and freeze-dried to preserve enzyme activity.
