Vitamin recommendations?

Thanks for all of the helpful feedback!! This has helped me a great deal! I am researching different options and will discuss with my dietitian at my 1 month follow up.

Off topic, but I was around a scale for the first time today and I told myself I wasn't going to step on a scale until my 1 month follow up. Well I couldn't resist. Tomorrow will be my two week mark since surgery. To my surprise I had lost 20 pounds. It's not much, but I'll take it! Hopefully I can continue to lose since I have a long ways to go! This head hunger is torture!
