Nutricost Niacin (Vitamin B3) 100mg, 240 Capsules - with Flushing, Non-GMO, Gluten Free

I had an allergic reaction to this medication. My heart race and my entire body turned red and I was very uncomfortable. (However, I realize that's because of me and not because of the medication, so I didn't mark it as 1 star.) Be careful and aware while taking this. At least for the first few times!! Almost had to go to the ER. Very scary.

I tried the 500mg of Niacin and the flush feeling was very strong and lasted an hour. This version at 100mg gives me a short light flush indicating it is working on my blood veins like the higher dose.

helpful for health problems but be aware of flushing

So I have mixed reviews here. While I'm aure that the product itself is quite decent I had a reaction that I now have come to know as "The Niacin Flush". I took a capsule as soon as I got them. I was excited. I had just bought several new supplements and I was eager to try them. Well about 1-1 1/12 hours later I started feeling hot. Ok I need to turn my aor on. A few minutes after that my lips started burning, then my face, and finally my chest and arms are 🔥 burning on fire. I felt as though I was being attacked by fire ants and needles all at the same time and at the rate of the speed of light! I didn't know what was happening. I was waiting for my throat to close. I yell to my husband "something is wrong, I need a doctor stat. My throat never started closing so I calmed down by the slightest bit and began to think " What in the H.E. double hockey sticks is going on? What did i do?" After racking my brain, all the while feeling like I was being microwaved it dawned on me.......could it be the niacin? So I head to my doctor on call...Google...and find out that yes indeed it was the Niacin Flush. Perfectly harmless, so they say. Upon further reading I found that there is a whole slew of folks that LIKE the way it feels. I myself absofrickenlutely am not one of them. So to anyone who is not familiar with this I say..BEWARE.

You can really feel the flush.

This supplement is very economical.

My previous Niacin purchase (500 mg.) from Amazon was a good investment, but the "flushing" lasted nearly all day - it got annoying. This new order (100 mg.) is more tailored to my needs. The "flushing" only lasts a short time, if at all.

Took one and i was really scared i started feeling really hot like a fever then felt tingling like needles and itching burning feeling in my body i wasn't sure what was happening i wanted to go to hospital but i have a 5 month old and 2 year old with no help. Im upset i ordered and didn't check reviews when i always do for ever purchase. I would not recommend anyone to buy this product!!! if you need B3 do it natural way threw food.
