Life Extension Vitamin B3 Niacin, Heart Health, Cholesterol & Energy Support, Gluten-Free, Non-GMO, 100 Capsules

Why did you pick this product vs others?:HOLY FLUSH! This product is awesome! I’ve never tried this high of a dose before. The negative comments are hilarious. If you read the bottle and understand how niacin works, then you won’t be surprised at effects you feel from it. Kicked in after about 25-30 minutes, my ears were on fire and I got red splotches all over my body (not just my trunk and face) Prickly, itchy, hot goodness! It’s uncomfortable but I look forward to oddly enough. You know it’s working! I prefer to take at night because it makes me sleep like a baby once the symptoms die down. Will buy again.

BEWARE!! Within 30 min of take I felt like I burst into flames. I was very red from head to toe. My heart was racing and my nose and eyes swelled. So much so that I ended up in the doctors office. I realized the dosage is so high that it caused an allergic reaction. My toes turned purple. This product is more than 3000 times the recommended daily dose, which I did not notice when I bought it. I found I should take 14mg -16mg and this is 500mg. If you want to feel like you were lit on fire from the inside out then by all means try this. Otherwise, do research and find one with correct dosage for your body size.

Okay I, like a lot of people discovered niacin watching some of those crazy food documentaries you can find on netflix. I watched "food matters" and there was a lot of talk about niacin. So I looked around and bought this to try out. Now i did a lot if research first and I have to comment on all the negative reviews on this product. most people thought they were having an allergic and they broke out in a red rash or "flush" that felt like pins and needles. (1) a flush is normal with high niacin doses and for some the desired effect. (2) you are not allergic to niacin you simply did not understand what was happening and it is not fair to rate this product with one star because you failed to do your homework. (3)I read a review or 2 that stated they were upset because they got no flush. before I took any niacin I actually read an entire book on... you guessed it, "niacin". It was called "the truth about niacin" which i also got on amazon. After reading it I learned that the less flush you get the more niacin you need. So If you are taking 3000 mg and get nothing than you should prob continue to take it and consider uping the dose. granted i'm no doctor and I have absolutely zero creditably in the medical field and this statement is based solely on the fact, I read a lot and research what ever i'm doing which in this case is taking niacin daily.On to my experience. the first time I took the niacin it was slightly uncomfortable but I was ready for the reaction and I just sat it out. It lasted about 20 minutes then it was gone. After a week the flush was greatly reduced and actually became very pleasant. I also noticed I was in a much better mood, more carefree and had way more energy. After 2 weeks the flush was gone and I had to stop taking it for 3-4 days to get the minimal flush back which for me is the best part. I'm not sure if anyone else experienced this but during my reduced flush all my muscles (I work out)became very sensitive to being massaged. I don't mean this in a weird way. I mean it literally. During my flush my wife would massage my arms legs back chest and it was incredibly relaxing. granted i can only talk my wife into the massage once in a while. I also noticed that while taking this cold symptoms were all most non existent. I have younger kids who bring home every cold known to man and a few times last year everyone in my house was sick and congested except for me. I had only minor symptoms compared to everyone else. I know it could be coincidence but I went a step further and tested the theory. the next time I got sick I stopped taking niacin and within a day I became congested and nasty. So I started taking the niacin again and poof symptoms gone it was like taking dayquil for your symptoms. When my wife saw this she began taking niacin as well. I would love to give it to my kids but they are to young and would not understand or like the flush at all.. So that's my story and im sticking to it.

Whew... the flush! If you are unprepared for the flush, read up about it FIRST or it will be quite disconcerting. The first time I took this product, I forgot completely that I added it to my morning vitamin mix and then I skipped a few days because I forgot. So Monday morning, I am at work and I take my vitamins with my morning tea, and all of a sudden I start feeling WEIRD... VERY weird. It starts with prickling in your nostrils, that spreads to your cheeks, then ears, which get very hot, then down the neck through your torso and out to your fingers and toes. It is like standing inside the sun... OMG. So I am looking at my secretary who tells me I look a little odd, like I am "pink". Heat is rolling off me in waves I cannot believe she can't feel it from 10 feet away. I AM the sun... My socks are clearly melting around my feet. I contemplate whether I should be worried as this is really very strange, then I start to process the sensations, and consider whether I am having a heart attack ... probably not, pulse is fine, or a stroke... probably not, as I am cogent, just HOT. I wrack my brain thinking I am having an allergic reaction but I haven't eaten anything yet today. So then I remember... OH... The Niacin. I read the reviews, I remembered the "flush". Well, that term does not accurately describe this sensation. It subsides after about 25-30 minutes but lessened some after 15 or so. Whew. That was my fault. So after thinking about it, that wasn't so bad, just different. You can feel that niacin working, coursing through your body. Oh, don't forget the distinctly metallic taste that floods your mouth while this is happening. Now, after a couple of weeks, it seems the flush is diminishing a little but I have decided that I kind of like it. So just be prepared when you try it for the first time if you are not accustomed to this sensation. The product itself is great, I would purchase again.

good quality .. good price excellent product

I really don't know how to rate this. It is definitely full flush niacin. 500mg seems to be a bit much, I'm surprised they didn't offer a 250mg option considering the extreme flushing reviews. I actually had 2 flushes. One at 30minutes and a second more intense flush 10 hrs later. Research shows it's not abnormal but might have to do with the amount of caffeine I consumed in the interim or the food contents in my stomach. I will probably reencapsulate the powder into smaller doses.
