The one important pre-operative supplement you should be taking is a high-potency daily multiple vitamin/mineral. It should include at least moderate doses of vitamin B complex and magnesium, which will help your body deal with the added stress of surgery. High doses of Vitamin C, flavonoids, protein and zinc are important for tissue rebuilding. You will find additional suggestions and cautions by going to our Presurgical Page and reading what we have to say there.
After surgery, when you are allowed to take in foods again, you can restart all the presurgical supplements and continue them for as long as you like.
