What daily vitamins should a vegetarian take to stay healthy? i'm a vegetarian & already take b12, vegetarian omega 3, multivitamin, and vitamin d-3.

Consider L-carnitine: Sounds like you are doing well with the vitamins you have chosen. A healthy vegetarian diet can provide nearly all the nutrients you need except for dha, an omega 3 which you can get from algae extracts. Carnitine is not a vitamin, but is a beneficial nutrient found mostly in red meat that aids in burning fat for energy & is good for our hearts & muscles, so consider taking l-carnitine too.
