Thymosin Alpha-1Strong clinical evidence

Immune modulator

A thymic peptide (marketed as Zadaxin), one of the most clinically validated immunomodulators, researched for chronic viral infections, immune restoration and as a cancer-therapy adjunct.

⚙️ How it works

Signals through Toll-like receptors TLR2/TLR9 on dendritic cells and macrophages, maturing dendritic cells and driving CD4+ T cells toward Th1 effectors (IFN-gamma, IL-2), activating NK and cytotoxic T cells while engaging tolerogenic pathways — bidirectional immune calibration.

🎯 What it's studied to help

Bars reflect the strength & volume of research evidence for each use — not a guarantee of results.

Backed by 30+ RCTs; approved in 35+ countries for chronic hepatitis B and used for immune restoration.
Calibrates immune tolerance via IDO/Treg pathways, studied for dampening harmful inflammation.
Immune-restoration framing in immunosenescence/aging, though direct longevity data are limited.
