Folic acid, also known as vitamin B9, is a water-soluble vitamin.
It is widely present in nature, and foods such as green leafy vegetables, beans, whole wheat products, and animal liver are rich in folate.
Folic acid plays a crucial role in the metabolism of the human body, participating in multiple key physiological activities such as DNA synthesis, repair, and cell division and growth.
Folic acid is an essential nutrient for maintaining normal physiological functions in the human body.
