Vitamin B9 supplements are a dietary supplement that provides an additional source of folate, a type of B vitamin that is essential for the growth and development of cells. Folate is important for the formation of DNA and RNA, and it plays a crucial role in the development of the nervous system of a growing foetus. Vitamin B9 supplements are often recommended for pregnant women, as well as individuals who are at risk of folate deficiency due to poor dietary habits or certain medical conditions. These supplements come in various forms, including tablets, capsules, and liquid drops.
