A study by the University of Minnesota Murso shows that taking large amounts of Vitamins may do more harm than good, and the study is another piece of evidence showing that certain supplements may have health risks. “In our study and studies like it, there is very little evidence that commonly used dietary supplements help combat chronic disease,” Mursu said. “We recommend that people reconsider whether to use supplements and instead focus more on a healthy diet.” The study linked many vitamins and minerals to a weak risk of death, including multivitamins, vitamin B6, folic acid, iron, magnesium, zinc and copper. For example, 40.8 percent of the 12,769 women who took a daily conforming vitamin died by the end of 2008, compared with 39.8 percent of the 10,161 women who did not take a daily multivitamin. Mursu said the increased risk of death “may be related to the generally higher concentrations of compounds contained in these supplements. The vast majority of supplements contain more nutrients than are consumed from food, and large doses of certain compounds can produce toxins, especially when taken over a long period of time and some of them accumulate in the body.” On the other hand, taking calcium supplements appeared to slightly (3.8 percent) reduce the risk of death in women, although the researchers noted that there was no link between gradually increasing the amount of calcium taken and a sustained decrease in mortality. Although vitamins and minerals are necessary for nutritional balance, excessive intake has shown no further benefit, and recent studies have called into question the idea that vitamin supplements provide a “safety net” for people with inadequate intake of specific nutrients. On the contrary, overconsumption may be problematic. Note: The Chinese have a long-standing belief in “tonicity”. It is important to understand that “medicine is toxic in three parts”. Drugs are for treating diseases. For healthy people, it is not necessary to take “tonic” under the premise of ensuring reasonable diet and healthy living habits. Only in the case of physical discomfort or some physical and chemical indicators abnormal, you can carry out some appropriate treatment under the guidance of a doctor.
