But the United States health experts found that the United States who have too much medication contains many vitamins and trace elements of health supplements. In fact, there was insufficient evidence to prove that multivitamin supplements beneficial to human health.

The associated press reported 18, United States national institutes of health organizations, health experts Committee believes that there is no research to fully prove that people can take to contain many vitamins and trace elements of health supplements to promote their own health.

He said: "about half the adults in the United States taking vitamins and microelements containing a variety of health supplements. However, we are not sure whether they can benefit. In fact, we are very concerned about the excessive intake of some nutrients for human health. ”

Many people believe that vitamins and trace elements essential to health and, therefore, intake, the more the better. But experts say that this is not the case. For example, excessive intake of β-carotene may increase smokers at risk of suffering from lung cancer. From the United States at Cornell University's nutritionists topazi · Brannon, excessive intake of antioxidant vitamin mangy disease may cause liver damage, excessive intake of vitamin A can easily cause neonatal diseases, excessive intake of vitamin E may cause some bleeding disorders. A number of vitamins and certain drugs while taking also dangerous side effects.

Vitamin shall:

Expert Committee said, the experiment proved that health supplements only on part of the disease has a preventive role. The following apply health supplements:

At the same time, many studies have shown that taking vitamin disease prevention in general are among other ways to promote their own health, such as eating plenty of fruits and vegetables, engaging in physical exercise, smoking, etc. It is difficult to determine vitamin is a major factor in bringing health.

Health care market supervision

Dr. McGinnis said: "we are dealing with a lot of health supplements in fact not be regulated. "This means that packaging label content is consistent with the true quality of medicines big problem.

In 1994, the United States Congress limited the United States food and Drug Administration for health supplements industry implementation oversight permissions. But with the vast majority of different drugs, health supplements not to experiment proved safe reliability, nor to prove that they are really good for your health.

United States national institutes of Health's Expert Committee calls for annual production has reached 230 billion health supplements industry strengthening supervision.
