Can a b12 deficiency disrupt your menstrual cycle?

B12 and Menstrual: There is no direct affect of B12 deficiency and irregular menses; however, often one deficiency of a nutrient, vitamin, or mineral is associated with others making it difficult to pinpoint cause and affect.

Yes: This happens because lack of B12 prevents the rapid growth of the glands and stroma that make up the lining of the uterus. If there is the least suspicion you are B12 deficient, get checked now using an appropriate lab and get treated at once.
