## Description

Each bottle contains 240 capsules, each containing 100mg of Niacin. Nutricost strives to provide the best supplements at the best prices. Please be aware that taking high dosages of Vitamin B3 (Niacin), especially when your body is not used to it, can lead to what is often referred to as the Niacin flush. A "niacin flush" is a temporary side effect of taking niacin; it's also a protocol used by some physicians. Studies have shown that niacin flush has a lot of benefits. However, if you are looking for just the benefits of vitamin b3 without the flush, we'd recommend using a different form of Vitamin b3 such as Niacinamide or Niacin from Inositol Hexanicotinate.

Review: 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 great if you like the flush feeling and I do. Takes about 30 minutes to start for me on a empty stomach.

### ⭐⭐⭐⭐⭐ Review
*by J***N on 11 February 2026*

50mg use to get my face flushed when I was working out. A couple years later I'm trying the 100mg and it's not having the same effect. It's no the product but probably my body is getting use to it or changing. I may not have enough of whatever it was that is needed in the skin that causes that helps niacin produce the flush. I forget what it was called. But Nutricost seems to be a brand I can trust.
