I would say B-12, but that is because B-12 is really poorly absorbed through foods even for some people. My family has a history of pernicious anemia, which is basically that your boday cannot take up enough B-12 no matter how much of it you eat. To combat that, my mom used to have to take these HUGE shots in her upper arm each week, but we found that sublingual vitamins actually work really well for her. Without high enough b-12 levels, too, you can't utilize the iron anyway, so it would be silly to take iron supplements if you don't have enough b-12 for the iron to help you feel strong.
All vitamins are TYPICALLY best absorbed through daily diet, so yes- DEFINITELY a good idea to increase those intakes, and yes, DEFINITELY a good idea to talk to your doctor and get bloodwork done to see if you are deficient at all. If you aren't, don't worry so much about supplements and just try to eat foods with more iron.
Another tidbit- you can get more iron if you cook with cast iron and from non-animal sources, but the body can more readily absorb heme-iron (the iron found in the blood of animals). I am NOT suggesting you give up your vegetarian lifestyle, especially if you aren't anemic at all, but be aware that supplementation, and even cast-iron cooking, may not be sufficient to increase your iron levels IF YOU ARE anemic. Hopefully that is not the case though :)
