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.
