Nutrients helped reduce recurring URTIs
Improved health issues with vitamin C and others

Doctors said that getting vitamins and minerals in the right amounts can boost immunity and protect against upper respiratory tract infection (URTI). In this study, 192 people with recurrent URTIs took a daily supplement containing vitamin C, vitamin D3, folic acid, and selenium, or a placebo. Researchers followed the two groups to measure the number, intensity, and course of URTIs.
After 16 weeks, nearly half of those in the placebo group had missed work compared to 14 percent for the supplement group. Doctors also measured circulating levels of the four nutrients and found that vitamin C, folic acid, and selenium increased in the supplement group, while vitamin D declined for both groups, but declined less in the supplement group. Those in the supplement group who began the study with insufficient vitamins C or D also had improved respiratory health.
