I was wondering if anyone could tell me why my nail color is purpleish red. I do have a problem with cold hands and feet. I have been tested for circulation problems from a specialist and say that i'm fine. I have also been tested for Raynaud's syndrome and they said I don't have that. I have been getting a little worse each year. I normally have to take a bath to get warmed back up. Does anyone have any suggestions and advise on any supplements or vitamin's i could take to improve this?
