Which B vitamin is important for the synthesis of DNA and found in leafy green vegetables?

Folate, also known as vitamin B9, plays a critical role in DNA synthesis and repair. It is essential for the production of nucleotides, which are the building blocks of DNA. This makes it particularly important during periods of rapid cell division and growth, such as during pregnancy and infancy.

Leafy green vegetables, such as spinach, kale, and romaine lettuce, are excellent sources of folate. Consuming these foods can help ensure adequate levels of this vitamin, which supports overall health and the proper functioning of the body's cells. Folate is also crucial in preventing neural tube defects during pregnancy, which further underscores its importance in DNA synthesis and cellular health.

In contrast, niacin (B3), thiamin (B1), and pantothenic acid (B5) have different roles in the body related to energy metabolism and enzyme functions, but they do not specifically contribute to DNA synthesis in the way folate does.
