What vitamins should be taken before surgery and which ones should be stopped before surgery?

Hello and thank you for your question. Every surgeon has their own protocol for pre-operative vitamins.  You are smart to think about this early.  I would recommend speaking with your surgeon.
Make sure you specifically look at before and after pictures of
real patients who have had this surgery performed by your surgeon and evaluate
their results.  The most important aspect is to find a surgeon you are
comfortable with.
Best wishes and good luck.

You should
discuss what medications, supplements, and vitamins you are taking, both
prescription and over the counter, with your plastic surgeon and have him or
her decide what you should and should not be taking. Your surgeon should be
certified by the American Board of Plastic Surgery and ideally a member of the
American Society for Aesthetic Plastic Surgery (ASAPS). It is important to
follow all pre and post-operative instructions.
