Review: I like the burn - When I was a kid, I used to pop Niacin to help flush my system and pass drug tests after smoking a bunch of weed. Now, I just use it to flush out my system every once and a while and get the warm fuzzy feeling of my veins dilating to the maximum. My only con is the (short-term) intense stomach pain if you take them on an empty stomach. Made in the USA with globally sourced ingredients
Review: Works! - Works great if you like the flush feeling and I do. Takes about 30 minutes to start for me on a empty stomach.

### ⭐⭐⭐⭐⭐ Kinda love the flush now lol worth it
*by L***O on January 12, 2026*

Yeah totally works! Even checked my blood work yet but definitely need to after taking these the past year. At first didn’t get used to the flush. The hot prickly sensation that using starts on my head and faces. I kinda like. Hits me different when I mixed other vitamins. Probably better to take it by itself after I eat something then later take my other vitamins and just space then out. But definitely worth it and will buy again
