An immune-modulating peptide approved in over 30 countries for immune support. Restores balanced immune function — particularly relevant given that 80% of autoimmune patients are female.
Thymosin Alpha-1 is a 28-amino acid peptide naturally produced by the thymus gland. It enhances T-cell maturation, promotes dendritic cell activation, modulates cytokine production, and restores the Th1/Th2 immune balance. Unlike immunosuppressants, it modulates rather than suppresses — upregulating underactive immune responses while dampening overactive ones.
80% of autoimmune patients are female. Thymosin Alpha-1 is particularly relevant because it modulates rather than suppresses immune function — important for women who need immune support without increased infection risk. It is approved in over 30 countries (though not FDA-approved in the US) for conditions including hepatitis B/C and as an immune adjuvant.
Well-tolerated across extensive clinical use in 30+ countries. Injection site reactions (redness, mild pain) are the most common side effect. Rare reports of mild fever or flu-like symptoms, typically transient.
It is not FDA-approved in the United States but is approved and widely used in over 30 countries for immune support, hepatitis treatment, and as a cancer immunotherapy adjuvant.
No — it modulates immune function rather than suppressing it. It upregulates underactive immunity while helping to balance overactive autoimmune responses, making it distinct from immunosuppressive drugs.
