Because optimal immune function is an important part of long-term wellness, it is important to provide support during times of high stress, seasonal changes, and when you are not feeling your best.

Your immune system is made up of cells, organs, and tissues that work together to protect your body from outside invaders. White blood cells, including natural killer (NK) cells and interferons all act as your body’s first line of defense. Supporting these vital components of your immune system can go a long way to keeping you healthy.
