Methylation is basically your body adding a small chemical group (one carbon + three hydrogens = a “methyl group”) to another molecule. Sounds tiny. But that little shift can completely change how your body functions.

PMS (pre-menstrual syndrome) refers to a group of physical and emotional symptoms that a woman may experience in the week or so leading up to the beginning of her menstrual cycle (when she starts menstrual bleeding) and subsides within a few days of menstruation.  

If you’ve managed to make it through most of your adult years with regular, “normal” periods but now suddenly find yourself with heavy or irregular bleeding, it can be rather alarming.
