Every winter, many of us worry about catching a cold or flu. But with added concerns related to the COVID and RSV, people are thinking about preventive health more than ever.
Luckily, you can fend off cold, flu or other illnesses by living a healthy lifestyle and embracing immune-boosting foods and supplements.
Below, you’ll find a list of herbs, vitamins, and even a few delicious snacks that can naturally improve immunity.
Herbs and Supplements for Immunity
-
Maitake Mushroom Extract
Researchers studying stress's potential to reduce the immune system's ability to fight infection found that an extract of maitake mushroom stimulated phagocytes, white blood cells that target bacteria.
A combination of extracts of maitake and the Ayurvedic herb ashwagandha proved even more effective at reducing stress and boosting immunity.
-
Olive Leaf
Olive leaf fights bacteria and viruses, and helps defend against colds and flu.
Research suggests olive leaf's compounds can modulate the body's inflammatory response and promote peak immune system performance.
-
Probiotics
Gut-friendly bacteria are needed not only for a healthy digestive system but also for a robust immune system.
Probiotics can be taken supplementally, or eat unsweetened yogurt with live cultures or drink kefir several times a week.
Other cultured or fermented foods offer beneficial bacteria too.
-
Vitamin C, D, and E
The immune system requires C to function, and D and E support immunity.
Vitamin C aids the production of anti-stress hormones and immune system proteins, and stimulates production of infection-fighting white blood cells.
-
Zinc
An essential mineral that promotes healthy immunity, zinc is found in every cell. Following zinc depletion, all kinds of immune cells show decreased function.
Women need 8 milligrams (mg) of zinc a day and men need 11 mg. Pregnant or breastfeeding women need a bit more.
If you feel yourself getting sick, lozenges containing zinc may help speed recovery from the common cold.
Immune-Boosting Foods

Almonds
Not only are almonds a delicious part of many meals and treats, but they also provide an all-natural dose of vitamin E that can support your body’s overall immune function.
-
Elderberry
Available as a supplement, elderberry is antioxidant-rich and contains vitamin C, a known immune booster.
Research indicates that elderberries may help prevent flu viruses from taking hold.
-

That strong flavor comes from sulfur, which fights viruses and gives your immune system a healthy boost.
Garlic enhances immune function to protect against infection and contains other substances (vitamin C, zinc) that support immune response.
