What is Thymulin?
Thymulin is a nonapeptide (9 amino acids) produced by thymic epithelial cells. It requires zinc to be biologically active and plays a crucial role in T-cell differentiation and maturation. Thymulin levels decline with age as the thymus involutes, and supplementation is explored for immune restoration and anti-inflammatory applications.

ModerateAnti-inflammatory effects
EmergingImmune system restoration in aging
EmergingZinc-dependent immune support
EmergingHow It Works
Thymulin helps train your immune cells (T-cells) to work properly. It needs zinc to function, which is why zinc deficiency can weaken your immune system. As we age, thymulin production drops, potentially contributing to immune decline.
