My go to niacin tablets. Have tried other brands but these always seem to give the best results. Slight scent to them that i can only describe as the smell of the niacin flush feeling. Maybe because the smell of the tablets makes me instantly remeber the flush. Nice dose to start with 100mg if just starting nacin. On an empty stomach the flushing can come on quick but for me it doesnt last cery long (approx 30 minutes) this is dependant on you though as everybody is different. Works fast. My skin always feels so nice afterwards, like it tightened up a little bit. Gives a slight "you're glowing" look (most likely because it increases blood flow to the skin by way of the nacin flush. The flushing can be uncomfortable but the no flush version doesnt provide the same benefits as this type. Small tablet that is easy to swallow. Considered low strength. But a good everyday dose.
