While nothing beats a well-balanced diet, there are a few supplements that may help provide the extra nutrients needed for growing a healthy baby. A good quality multivitamin specific for pregnancy is a great start. Choose one with active B vitamins (see my post on methylated B12 and B9) and no added fillers or dyes. I am always confused why a company would make pink prenatal vitamins that contain harmful, usually aluminum based dyes when we know how susceptible the growing nervous system of an infant is! If you live in northern climates and countries, taking Vitamin D is important for calcium metabolism and immune function. An increase in healthy fats is needed during pregnancy and can for the most part be obtained from diet; however, taking a good quality fish oil can also be beneficial.
