The short answer: the immune system isn't a switch you flip in October — it's a full-time system that depends on daily nutrition, real sleep, and a healthy gut. Supporting it year-round means feeding it year-round.* That's why the immune collection is the largest in the store: 57 whole-food formulas for a system that never clocks out.
Where does immune strength actually come from?
- The gut. A large share of immune tissue lives in and around the digestive tract — which is why gut health and immune health travel together.* (Our gut health primer explains more.)
- Daily nutrition. Immune cells are rebuilt constantly, from the raw materials you eat.*
- Sleep and stress. Chronic short sleep and constant stress draw down the reserves the immune system relies on.* See sleep, stress & mood.
What does year-round support look like?
Every day: real food, enough sleep, and foundational whole-food nutrition.* Seasonally: many patients add extra support during winter or travel — times when the system carries a heavier load.* When you feel run down: that's a signal to rest more and support more, not push harder.
Which formulas should I look at?

Can supplements prevent me from getting sick?
No supplement prevents illness, and you should be wary of any that claims to. Whole-food formulas support the immune system's normal function — the system that defends you is your own.* For infections and illness, see your physician.
