How can I support my immune system naturally?
Your immune system depends on the basics. Research points to four everyday habits that matter most:
- Sleep 7+ hours. In one study, people who slept less than 6 hours were about 4 times more likely to catch a cold after exposure. (Sleep, 2015)
- Keep vitamin D in a healthy range. A review of 25 trials linked vitamin D supplements to fewer respiratory infections, especially in people who were low. (BMJ, 2017)
- Wash your hands often. The CDC reports handwashing cuts respiratory illness in the community by about 16–21%.
- Move most days and eat colorful produce for the vitamin C, zinc and fiber your body uses every day.
What helps during cold and flu season?
Rest, fluids and the habits above. The CDC recommends a yearly flu vaccine for most people 6 months and older. Many customers also keep a few go-to products on hand, like vitamin C, elderberry, zinc lozenges or a homeopathic cold formula. See a doctor for a high fever, trouble breathing, or symptoms that last more than 10 days.
Where do supplements fit?
Products in this collection, from Smart Silver and PureDefense to Energique and DesBio homeopathics, are designed to complement these habits, not replace them.
