I switched to this because regular niacin made my face burn for an hour. This version gives me the B3 without any of that flushing, and I take it with breakfast since it helps my body turn carbs into energy. Two months in and I'm not going back.

The non-flushing kind is exactly why I made the switch — no hot prickly feeling an hour later like the regular stuff gave me. I take one with breakfast and it's been easy on my stomach, which wasn't the case before.

I switched to this because regular niacin made me flush bright red for an hour, and the non-flushing form fixed that completely. I take it with breakfast since it helps my body break down fats and turn carbs into energy. No weird aftertaste either.
