Doctors have conflicting opinions about taking multivitamins daily, but many are in collective agreement that prenatal vitamins benefit pregnant people. As it turns out, they help a lot in the growth of the baby. "Prenatal vitamins are important before and during pregnancy to help your body meet the demands of pregnancy and aid in your baby's development," Dr. Cordelia Nwankwo, a DC-based OBGYN, told Women's Health. Apparently, prenatal vitamins are just like regular multivitamins, except the dosages are higher because it needs to benefit both the mom and her child.

With heightened dosages, particularly folic acid and iron, Dr. Lucky Sekhon, a reproductive endocrinology and infertility specialist, shared with Woman's Day that people who aren't pregnant may experience "undue discomfort" with regular prenatal vitamin consumption as it can lead do constipation "due to higher levels of iron than what's needed." What's more, people with B12 deficiency may experience negative side effects, because "supplementing with folate while leaving your B12 levels untouched may actually cause a type of anemia known as megaloblastic anemia," Dr. Ryann Kipping, founder of The Prenatal Nutritionist, explained.

While it's true that prenatal vitamins can improve the appearance of your skin and nails, you may be better off getting those benefits elsewhere. After all, the market is inundated with supplements promising clearer skin, stronger nails, and more luscious locks.
