How much vitamin C the body needs—and especially whether supplements are a useful source—has been subject to controversy for decades. But a new analysis of pooled research confirms what some scientists claimed a long time ago: get your C if you want to live longer. For example, a 2013 study with 16,000 participants found that people with the highest vitamin C blood levels had the lowest risk of death and cancer over 14 years. Other studies have shown vitamin C protects against osteoporosis and kills drug-resistant bacteria. Benefits appeared to be due to the nutrient itself, whether from food or supplements. The bottom line: get your C for optimal health.
