What it is

Thymosin alpha-1 is a naturally occurring thymic peptide that helps mature T cells and modulate immune response. It is approved in more than 30 countries for hepatitis B and C and as a vaccine adjuvant, and it was studied during COVID-19. It is not FDA-approved.

What it's studied for

  • Chronic hepatitis B and C as adjunct therapy
  • Immune response in sepsis and critical illness
  • T-cell function in immunosuppressed populations

How it's used in practice

  • Used clinically in courses under supervision where approved
  • Discussed in research contexts around recurrent infection and immune resilience

What you should know before asking about it

  • Not FDA-approved; research use only in the United States
  • Immune modulation warrants caution with autoimmune conditions
  • Was removed from the FDA's bulk compounding list, which is why pharmacy access changed
