Practicing proper hygiene and regular daily disinfection certainly do the job of keeping the threat of the COVID-19 coronavirus at bay. However, there is another way to prevent you from getting infected by a virus that has no developed cure or vaccine to date, and that is by keeping your immune system strong and healthy. This is where vitamin C comes in.

In fact, the New York Post reported that "seriously sick" coronavirus patients in New York's largest hospital system were given massive doses of vitamin C, based on promising reports that it had helped people in China, where the virus originated. Though each dose was more than 16 times the daily recommended dietary allowance by the National Institutes of Health and though medication protocols varied from patient to patient, "the patients who received vitamin C did significantly better than those who did not get vitamin C," according to Andrew G. Weber, pulmonologist and critical-care specialist affiliated with two Northwell Health facilities on Long Island, NY. 

From capsules to gummies, listed here are 12 of the best vitamin C products that are guaranteed to boost your immune system and lower your chances of getting infected by the coronavirus:
