Vitamin B9 is a water-soluble B vitamin. It can be obtained from many foods and supplements. The form taken from supplement products is more easily absorbed.

It supports the formation of DNA and RNA, plays a role in protein metabolism, destruction of homocysteine, healthy red blood cell production, and healthy growth.

It can be obtained mostly from animal foods or supplements. It has duties related to red blood cells and DNA production. It supports brain and nerve cells to perform their functions.



It is transported in the body by combining with a protein called intrinsic factor. Therefore, in diseases such as pernicious anemia, B12 deficiency develops because there is no association with the intrinsic factor.
