As winter approaches, we’re all thinking about bolstering our defenses against colds and flu. But a robust, well-balanced immune system does more than fight off bacteria and viruses; it’s key in preventing more serious diseases, like hepatitis, leukemia, and other cancers.

This year, as cold and flu season enters its wintry worst, fight back: keep your system rock solid, with these 10 super-immune supplements to maximize your pathogen-fighting potential—and set you up for long-term health.

1. VITAMIN C

This powerful antioxidant has antimicrobial activities, improves components of the immune system, and reduces the risk, severity, and duration of infectious disease. Some studies show that large doses taken at the onset of colds can lessen symptoms. More importantly, vitamin C may also protect against some forms of cancer, including pancreatic, breast, colon, and cervical cancer.

2. MUSHROOMS

Reishi, maitake, cordyceps, and other medicinal mushrooms contain immune-enhancing lentinan and other compounds that ward off viral infections, lower inflammation, and help prevent bronchitis and flu. Studies have also shown their effectiveness in treating HIV-infected patients, reducing cancer risk, and inhibiting the growth and spread of tumors.

3. ZINC

This trace element is crucial for the development of white blood cells that destroy bacteria and viruses, and even mild deficiencies can increase the risk of infection. Studies show zinc may reduce the length and severity of the common cold, especially when taken as lozenges the first 24 hours of onset of symptoms. Other studies show zinc supplementation inhibits the growth of cancer cells and induces apoptosis (cancer cell death) and can help protect against prostate, lung, bladder, and other cancers.
