Green tea is highlighted as the preferred beverage for strengthening the immune system during the winter months, thanks to its unique combination of antioxidants and bioactive compounds. Experts point to the high concentration of EGCG, a powerful antioxidant, and L-theanine, an amino acid that supports immune response, as key factors in green tea's beneficial effects. Research suggests that consistent, daily consumption of green tea offers more meaningful immune support than drinking it only when illness strikes.

Matcha, a powdered form of green tea, is noted for its even higher levels of antioxidants, particularly EGCG, which may provide a stronger impact on the immune system. However, matcha contains more caffeine, making it best suited for mornings or afternoons. Other infusions like ginger and chamomile can complement green tea's effects by reducing inflammation and improving sleep quality, respectively.

While tea is not a miracle cure, incorporating green tea or matcha into a daily routine can be a simple and effective way to support immune health throughout the cold season.
