I'm a woman and a vegetarian. should i take iron supplements?

Depends : Have your blood count checked to see if you are anemic. Most vegetarians can get adequate amounts of iron through their diet provided they eat a healthy and varied diet.

Iron: Likely won't hurt. It depends which veggies you eat most.

Yes: That's my opinion. Militants may tell you that you can get enough iron from vegetables, but you'd need to take 20 tablespoons of that special molasses or 16 servings of broccoli to have a chance. Vegetarianism is the moral high ground but you need to supplement -- more than just iron. A veg-friendly physician can help you if you want to be safe. Best wishes.
