Thymosin Beta 4 (TB4) is a naturally occurring multi-domain (multiple active sections) peptide that is produced in the thymus gland. The thymus starts shrinking around age 15 and continues to decline until approximately 80-90% of its activity has decreased by age 40, this is when the chronic diseases of aging start becoming more prevalent. The CDC states that approximately 80% of aged individuals are affected by at least one chronic disease due to declination of thymus related immune function. TB4 provides a range of beneficial effects with the ability to stimulate and support tissue repair, healing, and regeneration for a range of tissues and organ systems. TB4 is shown to support the down-regulation of inflammation and pain; increase ATP (energy) production and protect and repair mitochondria; increase antioxidant and glutathione production; improve IGF-1 levels; stimulate stem cell proliferation, activity, function and maturation. Additionally, TB4 has significant antimicrobial functions; helps maintain a normal and balanced immune system; provides support and defence against environmental and internal toxins, including, pesticides, pollutants, antibiotics, alcohol, endotoxins mycotoxins and neurotoxins from infections and external sources; modulates dysfunctional immunity; supports the body’s repair functions in multiple systems of the body and supports the body’s ability to stay healthy during aging.
