The human immune system is a complex network that protects the body from pathogens and diseases. Among the various types of immune cells, T cells play a critical role in defending the body against infections and tumors. They are responsible for recognizing and eliminating infected or dysfunctional cells.

One approach to enhancing T cell activity is through supplementation. In this article, we will explore various supplements thought to help increase T cell levels and support overall immune health.
