What type of vitamins should i be taking?

Multi vit.: Not sure you should be taking any. If you eat a healthy diet there is no need for supplementation. If you must take them get a good generic brand once a day. If you plan to get pregnant switch to a prenatal vitamin.

Cheap if any: Most people get no benefit from vitamin-mineral supplementation, but i think a few do, especially in this era of varying lifestyles, sun-avoidance, vegetarianism, and fast-food. Vitamin d & iron are deficient in many of our diets. A drugstore-chain tablet is plenty. I'd rather see you avoiding fatty, greasy & salty food and taking time for aerobic fitness on a regular basis. Good luck, stay fit.
