Question: I have my b.s in Bio. and I want to get my M.s in nutrition Will I be able to be a nutritionist after my M.s ? 

Answer: Yes, if that is what you want, but if you combine your skills together you could easily apply for a position in a major food manufacturing corporation as a ingredients advisor to the board of directors which translates into a six figure salary and the potential to improve the health and well being of the customers of whatever company you land in.
