Vitamins are a huge family. As far as we know, there are dozens of vitamins, which can be roughly divided into two categories: fat-soluble and water-soluble. The former includes vitamins A, D, E, and K, and the latter includes B vitamins and vitamin C, as well as many "vitamins". Since the phenomenon of people lacking various vitamins has increased, and many people do not know much about vitamins, the editor lists the symptoms of major vitamin deficiency below to see which vitamin you are lacking.
A normal person needs 50-100 mg of vitamin C, 2500-3000 international units of vitamin A, and 300-400 international units of vitamin D every day.
Vitamins are organic compounds required for human nutrition and growth. If the body lacks vitamins, certain diseases will occur. Therefore, some people believe that vitamins are nutrients and the more they are taken, the better. Do people need more vitamins? The answer is no. The key to proper nutrition is "moderation". Excessive intake or lack of certain vitamins is not only unhelpful but harmful to the body.
