Alot of people find they are low in Vitamin D after surgery. I take that and also E as it is supposed to help with nerve health. I think some people take calcium supplements. As usual, ask your surgeon what s/he recommenRAB.
I asked my surgeon before my surgery if there was anything I could take to help get the fusion going. He sadly shook his head and said, "believe me, if there were, I'd tell you." Just eat a good, well balanced diet, take a multi-vitamin, and maybe some extra calcium. That's really about it.
