I. How many types of vitamins are there? – Do you know?

There are currently 13 types of Vitamins: Vitamin A, Vitamin C, Vitamin D, Vitamin E, Vitamin K and B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, vitamin B12 and folate). They are divided into 2 main types:

Fat-soluble vitamins

The group of fat-soluble vitamins includes: vitamin D, vitamin A, vitamin E and vitamin K. This type of vitamin is absorbed into the body through fatty tissues and fat. Therefore, if the body cannot absorb fat, it will lack these vitamins. In the process of absorbing them, acid is needed as an emulsifier because fat does not dissolve in the blood.

These vitamins play an important role in protecting vision, developing bones, supporting blood clotting and even preventing cancer.

Water-soluble vitamins

Similar to fat-soluble vitamins, water-soluble vitamins can dissolve in water. This also means that they are quickly absorbed into the body. A notable feature of this group of vitamins is that the body cannot store them. In other words, if the amount of vitamins taken in is too large, the body cannot absorb it all, and the excess vitamins will be excreted through urine.

Water-soluble vitamins include: vitamin B1, vitamin B2, vitamin B6, vitamin C, vitamin B12, etc. (Vitamin C and group B).
