I definitely think that the bariatric multi vitamins are the best to take. I have been taking them since my surgery, but I have to admit I do feel tired a lot though. I have added B12 shots also in addition to my calcium and fish oil, I also take iron. U may want to check to see if ur iron levels are low, that could also be a factor.
