While dietary supplements can support and enhance T cell production and function, it is essential to approach supplementation with caution. Consulting with a healthcare professional before starting any new supplement regimen is advised, particularly for individuals with underlying health conditions or those taking medications. Additionally, maintaining a balanced diet rich in vitamins, minerals, and other nutrients, along with regular exercise and adequate sleep, remains the foundation of a healthy immune system. By integrating these strategies, individuals can work towards increasing T cell levels and strengthening their overall immune health.
