Vitamin C
Mark Levine, MD, always laughs when he’s asked about taking vitamin C supplements. He’s a researcher at the National Institute of Diabetes and Digestive and Kidney Disease, and he has performed multiple meticulous studies on how the body reacts to vitamin C.
Even if there’s research that shows how vitamin C is extremely good if you suffer from cancer, cardiovascular disease, age-related macular degeneration, or you simply have a cold, it won’t work if you take ONLY this supplement. “The best evidence when it comes to vitamin C is shown from examples where individuals had a diet rich in fruits and vegetables.”
Even more, his research proves that the body regulates vitamin C levels, so it’s useless to load up on God knows how many megadoses you find in popular supplements. “The body is working hard to absorb low amounts of vitamin C. But the bigger the dose, the lesser you absorb, and you excrete the extra vitamin C through your urine in only a couple of hours.”
Should I even mention that there’s no need to take a supplement? Because amounts that are higher than the RDA of 90 mg for men and 75 mg for women are extremely easy to get from your diet. According to CDC, only 6 percent of the population has a vitamin C deficiency.
