• DNA Synthesis: Vitamin B12 is involved in the synthesis of DNA, the genetic material that carries instructions for cell growth and function. Adequate vitamin B12 intake supports proper cell division and growth.

Other Sources of Vitamin B12

While beef jerky can be a good source of vitamin B12, it is important to incorporate other sources into your diet to ensure adequate intake. Other foods rich in vitamin B12 include:
