Although excessive intake of vitamins can be poisoned

 

Vitamins are organic compounds necessary to maintain the body's normal physiological functions. For some modern people, a variety of vitamin supplements have emerged as a result of their inability to meet their health aspirations solely from the intake of vitamins in food.

The latter is mainly vitamin A, D, E, K, do not dissolve in water, so stored in the liver and fat, and eventually excreted through the lymphatic system, the excretion process takes a long time.

Reasonable diet, no obvious illness without additional supplements

As many workers because of high work intensity, stress, often staying up late, smoking and drinking, eating irregular or diet control diet to lead to nutritional deficiencies, the body showed sub-health, then take vitamin supplements is a viable way.

 

In addition, special populations such as pregnant women and adolescents with developmental age may need to be supplemented with specific vitamins. However, they must be taken after consultation with a doctor and taken as much as possible of natural foods.

 

"If there is a lack of vitamins caused by the disease, such as night blindness, you need to be targeted under the guidance of a doctor to supplement vitamin A, but should not blindly, should find the cause of symptomatic treatment, eat in the diet can eat animal liver, egg yolk , Carrots and other foods, intake of food from the dimension A. In addition to the complex vitamin supplements should be cautious.
