Yes, I started taking vitamins, biotin, calcium / magnesium / potassium supplements. I believe putting my body into a healthy pre-op state has helped me with a successful post-op. But I also started these supplements 8 months before surgery (6 months before I finalized my plans to have surgery).
I wouldn't over do shakes, but I would try a few to see what flavors you like, but don't over buy as you will quickly find out they will not be your best friends post op.
