Can Niacin be used for the treatment of Raynaud's Disorder?

Depends on the severity. I've taken Niacin up to 1000 mg daily and it did nothing. I have a severe case and have flares about every two months. So far I've been lucky and not had my fingers amputated, but they have suggested it a few times. Niacin with help with Berger's syndrome since it's a much less form for raynaud's. Oddly enough if it's bad, medication for high blood pressure is now being used and it does help a lot of people, but not me.

Yes, at one point and time my doctor had me take niacin 1 per day added to my other persciption medication. I also found on the internet reading that you can do this too. I would ask your doctor because you may be taking a medication that may interfer with this or you could ask the pharamist. I know some people takes more than 1 if your not taking a perscription for this cause, but i think if you take too many all the time you would have to have your liver checked.
