great product !!!!
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.

The heat of a thousand suns... Awesome.
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.

Flushing, is painful sensation as it “bloomed”
“Flushing” cute name for your body turning bright red & burning. Lowers BP, caused severe dizziness upon standing. Also HOT FLASHES! Both women & MEN. My husband & myself added Life Extension Niacin to our daily vitamins. I experienced side effects about 10 days after taking them. I thought it was a reaction to something else. I made 3 trips to the local Urgent Care. Switched, shampoos, soaps, did the elimination diet, changed anything that came in contact with my skin, detailed my car, even bathed the cat and started to carry Benadryl tablets. I had a follow-up with an allergist, everything came back negative. My husband was having hot flashes. Since he had not mentioned he had dizzy spells & until after he fainted be getting up in the middle of the night. Then today, he started to get the flushed red blotchy burning skin. I did some research, we narrowed it down to the Niacin. We thought because it was a vitamin, it would be safe. In our case it had bad results. So be aware!

Woooooooo!!!!!!
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.

Good but severely itchy
A great product, but I had extreme itching for 20 to 30 minutes. After my first dose, I threw the rest of the bottle away.

Swallowing vitamin B3 (niacin) as nicotinic acid results in numerous health benefits that most people aren't aware of
The health benefits of swallowing vitamin B3 (niacin) as nicotinic acid include: (1)better heart health [from improved vasodilation and plaque control] (2)better oral health [gum disease is a comorbidity of heart disease] (3)better bone health [osteoporosis is a comorbidity of heart disease] (4)better kidney health [from improved vasodilation and plaque control] (5)better brain health [from improved vasodilation and plaque control] (6)better eye health [from improved vasodilation and plaque control of ocular arteries and veins] (7)better ear health [from improved vasodilation and plaque control of cochlear arteries and veins] (8)better sexual health [from improved vasodilation and plaque control of both penile and vaginal arteries and veins] Meanwhile, the other 2 very popular ways of increasing our blood levels of HDL good cholesterol can sometimes kill us: (1)drinking a half cup of wine every day [even light-to-moderate alcoholism will greatly increase our risk of death from esophageal cancer and kill a significant percentage of our brain cells] (2)exercising regularly [a substantial percentage of the people who exercise regularly will die of sudden heart attacks, traffic accidents, or bone fractures; during exercise, they will regularly waste lots of their precious time and suffer continuously; during exercise, they might get infected with sexually transmitted viruses from sharing sweaty exercise machines, develop osteoarthritis of the knee from jogging, develop sunburns, skin cancer, or permanent eye damage from solar exposure, or develop scars or injuries from slipping, tripping, or falling] If the itchy or hot sensation called, "flushing," definitely occurs after swallowing a vitamin B3 supplement, then it indicates with 100% certainty that nicotinic acid is present in that vitamin B3 (niacin) supplement. However, if flushing does not occur, then we could try to prove that little or no nicotinic acid is present in that fraudulent supplement by simply swallowing a much greater quantity or dosage of that fraudulent supplement. We could also try to prove that little or no nicotinic acid is present in that fraudulent supplement by swallowing several other brands of vitamin B3 (niacin) as nicotinic acid on a rotating, alternating schedule. If flushing never occurs under any circumstances, then it would prove that our body is somehow unable to ever experience flushing. However, if flushing only occurs after certain brands are swallowed but not after swallowing the fraudulent supplement, then it would prove that the fraudulent supplement contains little or no nicotinic acid. People who just want to prevent a vitamin B3 deficiency and don't want to experience flushing should purchase vitamin B3 (niacin) as niacinamide. Niacinamide-containing vitamin B3 supplements are frequently marketed as "flush-free" niacin supplements. However, people who not only want to prevent a vitamin B3 deficiency but also want to derive the fantastic health benefits of (1)much higher blood levels of HDL good cholesterol, (2)lower blood pressure if blood pressure is higher than it should be, and (3)better overall health and well-being should purchase vitamin B3 (niacin) as nicotinic acid.

Please Watch Your Dosage!
I am not badmouthing this product. But you need to know that you should go slowly and work up to the right dosage. I'm sure the product itself is good. I'm still alive and feel fine. But here is what happened to me. The warning on the label and the comments from the reviewers discuss the flush and the tingling or itchy feelings. Some like the feeling but others find it unpleasant. I just want to warn others about my experience. "Unpleasant" is an understatement in my experience and I know everyone is different but I want to reassure or caution others. One capsule is 500 mg and the daily recommended dosage is only around 10-20 mg! I only took one and I am glad my heart is strong and that I'm here to tell you that my heart rate went up to 155 and my top number blood pressure went up to 167!! I can't remember the bottom number. I was never so scared in my life! It was the most horrible experience. I thought I was going to die. The flush feeling was like I was burning up. I was bright red and my skin was very hot. The heart pounding felt like I was going to explode. I was alone and called 911. I called my husband and he called a neighbor to help. I called another neighbor to take my dog. I'm so grateful they were there because my husband was about an hour away. They kept me calm and one texted my husband with my status. The measurements above came from the paramedics. They carted me off to the emergency room because my heart rate was still high. By the time I got there, I was almost back to normal. They released me almost immediately. Just so you know that it isn't only an isolated experience, the emergency room doctor and the paramedic told me that this was VERY common. In fact, the doctor said that I was his 2nd one that morning. The other guy had taken 8!!!! As the doc said, "Imagine how uncomfortable he is compared to you!" That word is a HUGE understatement!
