What Does Your RDI Look Like: Vitamin B12


Vitamin B12 is extremely important for your health because it helps maintain nerve cells and red blood cells. More importantly though, it's needed in order to make DNA, the genetic material found in every cell in your body. An adult woman needs 2.4 micrograms (mcg) of B12 a day. If she's pregnant she needs 2.6 mcg, and if she's breastfeeding, she needs 2.8 mcg. That's a pretty small amount, but the thing is, it's found mostly in animal products, so if you don't eat meat, you want to be sure to get B12 from other sources.
