Positive experiences
“In my experience, niacinamide (not niacin) 1000-1500mg a day worked wonders in about 5-7 days.”
“sharp improvement in my working memory and recall when taking it ... night and day difference in my memory”
“Niacinamide is a great anti acne supplement. I take it orally, 1500 mg a day in one slow release tablet. It's completely changed my life! I'm so much less oily now”
“melatonin in conjunction with 1000mg niacinamide helped me more than anything else”
“Niacinamide (500mg/day) had an incredible effect for me. I had frequent small pimples and an uneven skin tone... It was an ongoing issue for a long time and I tried a lot of things, until I found this.”
Negative and mixed experiences
“Personally, I tried going the niacinamide/sustained release niacin path before I started nicotinamide riboside. No impact whatsoever.”
