Which vitamin is also known as folic acid?

Folic acid is commonly recognized as Vitamin B9, which plays a crucial role in DNA synthesis, repair, and methylation, as well as cell division. It is essential for the production of red blood cells and is particularly important during periods of rapid growth such as pregnancy and fetal development. This vitamin helps prevent neural tube defects in developing fetuses, making its intake vital for expectant mothers.

Understanding the distinct functions of the various B vitamins helps to clarify why B9 is specifically identified as folic acid. Other B vitamins, such as B6 and B12, serve different roles within the body: B6 (pyridoxine) is important for protein metabolism and cognitive development, while B12 (cobalamin) is crucial for neurological function and red blood cell production. Vitamin C, on the other hand, is not part of the B-vitamin complex and has different functions related to immune function and antioxidant activity.
