Immune restoration with age

In plain English

Your thymus shrinks with age and produces fewer T cells. Thymalin is researched as a way to support immune function as that happens.

How it works

Modulates T-cell differentiation and maturation, restoring aspects of immune competency in aging models.

What researchers study

Immunosenescence, lifespan, and infection response in older populations.

Internet discussion

Discussed with Epitalon in classic 'Khavinson protocols.'

Quick summary

Thymalin is a thymus-derived polypeptide complex researched for immune restoration in aging.
