Dr. Neal shares how to truly strengthen your immune system during cold and flu season, emphasizing foundational habits over trendy supplements. He explains how proper nutrition, regular exercise, sleep, and a healthy gut all work together to keep your defenses strong, especially in winter climates like Minnesota’s.

Quotes to ponder:

"Pretty much all of the vitamins and minerals have some role in keeping the immune system working at its best but some are more involved than others."

"Exercise makes our immune cells more active and ready to fight off dangerous microbes."

"It’s estimated that about 70% of our immune cells can be found in the gut."
