I carried on with the vitamin c,only because the nurse said I was ok to do so,but we are all given different instructions,I would say follow the advise you are given,as the service seems to be tailored to you as an individual.The nurses work alongside the surgeons,so they know what the surgeon prefers.
For my BA I used Mario Russo,he recommended Arnica and vitamin C
For my Rhinoplasty I used Stepan Gonschior he said do not take Arnica,he didnt recommend I take any supplements,so it really does depend which surgeon you use.xxx
