I ordered Niacin a few days ago and it arrived in the mail today. I had come across discussions of Niacin on the Acne.org boards in the past, but it wasn't until last week that I noticed people saying it cured their oily skin. Naturally, I was intrigued. It seems like most people who take Niacin see results, sometimes dramatic, with their acne. My acne situation isn't too bad but I do get the occasional breakout, so even if this doesn't help my oily skin it might at least help stave off the acne.
I bought Nature's Way Niacin 100mg (nicotinic acid). Niacin supplements come in flush and non-flush forms. The Nature's Way brand is the flush version, which I opted for because I've heard that long-term use of the non-flush form can cause liver damage. The flush took a while to set in. 30 minutes after swallowing the capsule, I was beginning to wonder if I was even going to have a flush. Then all of the sudden I felt a mild pins-and-needles feeling all over my body, similar to the feeling you get when your foot falls asleep. Certain spots flared up a little bit, like my arms. All in all it wasn't bad. I'm starting off with one capsule a day and I'll gradually ramp it up to 500mg or so.
