 There's nothing else on the market like it. I've done tons of research. Vitamin C has over 100,000 studies, and it's really survived the test of time. What do these studies suggest? What are they saying? Well, I'll give you a couple headlines. This study was conducted at the University of California, and it found that people who took vitamin C above the RDA, above 60 milligrams, increased their lifespan up to six years. They also found that deaths from cardiovascular disease were reduced over 40%.
