Take Your Vitamins

Low levels of vitamin D can affect immune strength. Consider a 1,000-IU supplement if you spend a lot of time indoors or don’t drink much milk. Meanwhile, zinc—found in chocolate, pumpkin seeds, and tahini—has been proven to boost the immune system, while zinc lozenges (like Zicam and Cold-EEZE) may help prevent the spread of respiratory viruses. According to Maier, vitamin C supplements like Emergen-C and Airborne have not been proven effective as preventive measures, but when taken at the onset of symptoms may reduce your downtime. And beware over-the-counter, anti-flu medicines, which have not been shown to be effective.
