I couldn’t judged about it’s effectiveness as I couldn’t physically see or feel any improvement. Seems to be no difference compared to the natural factors no flush niacin. But it definitely didn’t give any niacin flush just like what it stated on the packaging. Please press the like button if the review is helpful. Thank you.

Great product. I drink it with B1 and B 6 to help to have more energy and to help metabolism of carbohydrates. Good quality. Very good size for me to drink it one moth. It also help to calm my nervous system.
