When I went to my PCP today and told him about the trouble I am having with an incision not healing as it should, he suggested that I take 250mg of vitamin C twice a day because he said he has seen in it helpful in nursing homes when patients are trying to heal. I am not going to take any until I talk with my other doctors and get their approval, but I was wondering if anyone had been told of this effect of vitamin C in improving healing or had had his or her own doctor recommend it? Can vitamin C interact with Prograf, tacrolimus? I will be seeing my nutritionist on Monday and will talk about this then. I was just wondering if there is anything that I should know that might be helpful for that discussion. Thank you for any response. Best of wishes for good health to all.
