Looking at old forum posts on niacin, I seem to be finding a great amount of articles both supporting and attacking niacin usage for general longevity. I've read multiple sources stating that it can be bad for your liver, and this post in particular has some discussion on niacin as possible factor in Parkinson's:

What are your thoughts? I was about to try niacin since I read it can increase libido, but to me there seems to be too many risks. Perhaps the risks are dose-dependent? If so, what it is the optimal dosage for someone who wants to take it just for general health and doesn't have heart problems?
