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.

Excellent product. Because I take 325mg of Aspirin per day - I barely have the Niacin Flush. This is another reason it's beneficial to take aspirin. I take 2,000mg of this Niacin per day 1,000mg in the morning and 1,000mg in the evening. I've ordered twice from this seller and Amazon does an excellent job of shipping fast. Thanks!

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.
