Review: Amazing product - I really wish people would refrain from posting bad reviews prior to educating themselves about a particular product. This is REGULAR Niacin, it WILL MAKE YOU TEMPORARILY RED and flushed, you may feel hot or even cold for up to maybe an hour,this is NORMAL!!!!! It's irritating when people give a product I'll reviews because they fail to realize this. I use Niacin for blood flow to the scalp while doing scalp massage or facial massage, it really gets your blood circulating. I have been using it for 3 years now and I really love it!
Review: Reliable and cheaper without sacrificing quality. - NOW makes reliable supplements and I am an avid flusher with Niacin and I have been using NOW brand regularly for 15 years. They are reasonably priced and usually cheaper and more reliable than most competitors. There are some really good companies in the nutritional supplementation industry.

### ⭐⭐⭐⭐⭐ Review after taking and reading other reviews
*by A***Y on April 7, 2025*

I read reviews after I bought this while waiting for it to come in and I was worried about taking this because people where saying they had to go into the hospital over it. I'm taking this trying to lower my cholesterol levels and I was worried about the flushing but honestly it just feels like a sunburn (but not sensitive with touch like a normal sunburn) on face, ears, nose, arms, belly and in my case other sensitive areas. The flush only last 30 mins to an hour on me after that I'm fine. I do notice slight nausea after taking it during flush but not like I'm going to get sick from it. Sometimes I get a weird aftertaste that last awhile. The capsule is about the size of extra strength tylenol.
