Thymosin Alpha-1 is an endogenous peptide derived from prothymosin alpha, produced primarily by thymic epithelial cells. It has been studied extensively for its immunomodulatory properties and is approved in several countries for use in the context of hepatitis B, hepatitis C, and as an adjunct in certain immunocompromised states.
The following areas have been examined in research contexts. This does not constitute medical advice or imply proven efficacy in humans.
- Immune Support
- Anti-Aging & Longevity
Research indicates Thymosin Alpha-1 may enhance T-cell maturation and differentiation, augment NK cell activity, upregulate MHC class I expression, and modulate cytokine production including interferon-gamma and interleukins. It is thought to act primarily through toll-like receptor and dendritic cell pathways.
Approved in over 35 countries (as Zadaxin/thymalfasin). Generally well-tolerated with injection site reactions as the most common adverse effect. Not FDA-approved in the US.
Selected peer-reviewed papers from research literature. These are educational references only and do not imply proven efficacy or safety in humans.
