The vitamin that is most responsible for the production and RNA and DNA is Vitamin B9 also known as Folate. It can be especially important for infants, adolescents and pregnant mothers, as Vitamin B9 aids in rapid cell and tissue growth. A deficiency in Folate can cause megaloblastic anemia which is a condition that occurs when the red blood cells in the body are larger than normal and there’s fewer of them. Vitamin B9 deficiency may also cause higher levels of anxiety and depression, supplementing it may help with these symptoms.
