A 70-year-old eats at least three vitamins a day, which causes overdose of B12 in the body. When the overall vitamin is taken, the body is already full of high-concentration B12. When it is not taken at first, symptoms of B12 deficiency occur, such as blood loss and mental depression. Nutritionists call for a balanced diet at normal times, and increase the use of comprehensive vitamins when nutrition is confirmed, and you can take up to one comprehensive vitamin a day.

Nutritional tutor Sang Miaoling, a nutritionist at the North Health Branch of National Taiwan University Hospital, said that many people are polite to take comprehensive vitamins, especially to grow up. To show filial piety, children often give health foods during the Chinese New Year, but they should be careful to overdosage. For example, due to poor teeth, the skin hair people reduce their consumption of animal foods such as meat, which in turn reduces their diet to vitamin B12. Some people take vitamins when they are stable to prevent symptoms such as obstruction of obstruction of blood, numbness and pain. At this time, group B is also supplemented, so they may eat too much.

Simple Ling Explanation: Vitamin B12 is a water-soluble vitamin and is usually supported by the body system. As long as you have a balanced diet, you don’t have to worry about vitamin B12 deficiency. Unless you are a vegetarian, have had gastrointestinal surgery, and cannot eat animal foods, you may have the risk of vitamin B12 deficiency.

Shang Miaoling said that generally lacking vitamin B12 will not cause immediate risk, but if it is severely deficient, severe blood loss, mental depression, skin numbness and other symptoms will occur. However, excessive supplementation will cause the body to be ill with excessive vitamins to maintain basic functions. It is recommended to supplement vitamins, and you should first consult the nutritionist and then supplement when there is a lack of risk.
