维生素是生物生长和代谢所必需的微量有机物,存在于许多天然产物中,大多不能在人体内自行合成,需由外界食物中取得。但是维生素不是无害的,服用太多可能损害健康。据联邦德国报导,可溶解组织中的脂肪,尤其是能保持视力的维生素A,吃多了会引起中毒。可能引起的后果是:脱发、掉皮屑、黄疽病、夜里盗汗、呕吐或月经失调。维生素B 消除紧张的作用没有得到证实。科学家 Vitamins are trace organic substances necessary for biological growth and metabolism. They exist in many natural products, and most of them can not be synthesized in the human body by themselves and need to be obtained from outside food.

The possible consequences are: hair loss, dander, jaundice, night sweats, vomiting or menstrual disorders. The role of vitamin B in the elimination of tension has not been confirmed. the scientist
