Peptide
Thymosin Alpha-1
Thymosin Alpha-1 is used or studied for enhances immune response and related immune, inflamation and longevity goals. Potential benefits and safety depend on indication, formulation, dose, and medical supervision.
In depth
How it works
Thymosin Alpha-1 is a naturally occurring thymic peptide involved in regulating immune signaling, including interaction with toll-like receptors, and in supporting T-cell maturation and immune surveillance.
What the research shows
Under the brand name Zadaxin, Thymosin Alpha-1 is an approved pharmaceutical in roughly 35 countries for chronic hepatitis B and C and as an immune adjunct, though it does not hold FDA approval in the United States. It has been studied in trials for severe sepsis, hepatocellular carcinoma, and as an adjunct treatment during serious respiratory infections, including a registered COVID-19 trial (ClinicalTrials.gov NCT04487444).
Safety and who should avoid it
Injection site irritation is the most commonly reported effect. Because it modulates immune activity, anyone taking immunosuppressive medication or managing an autoimmune condition should discuss its use with a clinician before considering it.

Frequently asked questions
Is Thymosin Alpha-1 FDA approved?
It is not approved in the United States, but it is approved as Zadaxin in roughly 35 other countries for chronic hepatitis B and C and as an immune-support therapy.
Was Thymosin Alpha-1 studied for COVID-19?
Yes, it was investigated as an adjunct treatment in a registered clinical trial (ClinicalTrials.gov identifier NCT04487444).
Does Thymosin Alpha-1 boost or suppress the immune system?
It modulates immune activity rather than simply boosting it, helping regulate both under-active and over-active immune responses depending on the clinical context.
