It is best not to take vitamin pills for a long time when you are healthy. A new study found that taking vitamin C supplements may accelerate the hardening of arteries. The results were surprising, and experts say more experiments are needed to determine whether taking high-dose vitamin supplements is harmful. However, they also point out that even if the above research results cannot be 100% confirmed, many health experts have already recommended that people should not take large doses of nutritional supplements and should absorb these nutrients from food. Many people like to buy and take various nutritional supplements on their own, thinking that this will be beneficial to their health, but in fact there has never been scientific evidence to prove this is true. Theoretically, vitamin C and other nutrients can reduce oxygen damage to body organs and protect the circulatory system and other organs. However, when you extract an element from food and then take it in large amounts, you don’t know whether it will be a blessing or a curse to the body. . Dermatologist James Ware, who led the study, presented their findings at an American Heart Association meeting in San Diego. He and his research partners from the University of Southern California studied 573 apparently healthy middle-aged men and women employed at a Los Angeles power plant, 30 percent of whom regularly took vitamin supplements. The results of the study did not find any harm in absorbing large amounts of vitamin C from food or taking large amounts of vitamin C supplements, but they found that those who took vitamin C supplements had accelerated thickening of the walls of blood vessels in their necks. In fact, those who took higher doses of vitamin C supplements had their blood vessel walls thicken faster. People who took 500 milligrams of vitamin C a day for at least a year had blood vessel walls thickening at a rate two and a half times greater than those who didn't take vitamin C supplements. If he is a smoker, the speed increases fivefold. ?
