Vitamin B12 plays a crucial role in overall health, particularly in reproductive health for both men and women. A deficiency in this essential vitamin can impact fertility, leading to complications in conception and pregnancy. In this article, we’ll explore how Vitamin B12 affects fertility, its benefits, sources, and ways to optimize levels for better reproductive outcomes.

What is Vitamin B12?

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that supports red blood cell formation, neurological function, and DNA synthesis. It is primarily found in animal-based foods and fortified products. Since the body does not produce B12, it must be obtained through diet or supplements.
