If you have Niacin sensitivity, be very cautious if you take this brand of Niacin because it is VERY potent. I’ve taken different brands of Niacin before and other than feeling warm temporarily I would have no side effects. Within 15 minutes of taking this brand, I felt the super warm flush like my head was on fire that started in my scalp and worked its way down to my feet. My skin got red like I had a sunburn and it was itchy all over like I had a rash. I also made the error of taking the capsule on an empty stomach and I briefly had a stomach ache that stopped before the raging niacin flush commenced. The reaction lasted less than an hour and then it passed. I could deal with the flush, but the itchiness drove me crazy.
If you’re very sensitive to the side effects of Niacin, you should probably buy the flush free version of this product.

If you are already taking large doses of Niacin then you will like this product just fine. This product seems to be of good quality and the price is good too. However, If you have not taken 250mg or more of Niacin before, beware of the Niacin flush effect this will most likely have on you.
I took two capsules (1000mg) and my experience was pretty bad. My skin turned beet red and felt like it was on fire, I hurt all over, and felt like throwing up several times. This lasted for almost 4 hours (most all of it in bed) and was one of the worst things I’ve had to go through in a long time. If it’s your first time taking Niacin, only take one pill and do some research online about the effects of Niacin flush and how to minimize them before you buy this product. I hope this information helps!

I started Niacin today to help with vestibular migraines. About 30 minutes after taking it, I had a severe reaction. It is referred to as the “Niacin flush,” but is flushing is only supposed to happen with very high doses. I only took one of these. Either this is a very potent mixture or I am particularly sensitive, or both.
If I’m being completely honest, I thought I was dying of shock. I have never been to the ER in 37 years of life, so I assure you I am not an alarmist or hypochondriac. If we weren’t in the middle of a pandemic crisis, I would’ve been in the ER today. That is how alarming my reaction was.
Very suddenly, I felt very hot in my face and head. My skin was burning and prickly. My face swelled up, I turned bright red as if from sunburn all over my face, neck, chest, arms. It spread down my stomach to my legs. I was shaking violently and spiked a fever of 101-102. I couldn’t tell if I was hot or cold, I was under blankets with ice packs all over my body. I couldn’t hold my phone from the shaking, so my husband was texting a nurse friend for advice. She thought I was spiking a violent fever from covid-19 and advised me to take Tylenol right away. I was also nauseous.
The flushing and swelling subsided after about 2 hours, but my skin still feels sensitive and prickly and I’ve got no appetite and a massive headache 4-5 hours later. My body temp is still hovering around 100-100.5.
This supplement is going in the garbage, because that was a truly terrifying experience. I strongly advise anyone who wants to take Niacin to start at a much lower dose!

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!

I was told by a couple of sources that NOW is a reputable brand. I have started taking 2000 mg daily. At first, I started with 1000 mg of another brand. I believe it was called SUNRAY. I had more flushing with that brand. This one gave me a little flushing at first, but now I dent even notice it, even though I take 2000 mg. per day. I have clogged arteries around my heart and take cholesterol meds, so it is my understanding that 2000 mg of Niacin would most likely be beneficial. Very little if any flushing now since my body has gotten used to it. So I would recommend it.

I actually got this for someone else because I had read it helps with a variety of things from hair and skin to mental clarity and vitality. I try everything on myself before I give it or recommend it to someone else. So I popped a pill of this and was expecting a warm “flush”…. but My scalp started to burn, and tingle like pins and needles, then my face. Not just warm. HOT. Then Bright tomato red. My ears started pounding. I was sweating, like just jogged around the block sweating. I could feel the blood pulsing in my head. I was scared, but I didn’t feel bad. So I wasn’t too – too worried. Then the hotness/fever and tomato color moved slowly down my body like a slow moving wave. Took about 10 minutes to start, Lasted about 2 hours. Then I was glowing. I literally felt like I was radiating. And I felt lighter and more alert. It was fascinating.
I took it full strength 2 more times, thinking the next few times would be more mellow. Nope. So, I’ve been opening the capsules and sprinkling half of it into whatever I’m drinking. Coffee, Gatorade, water. This makes flushing immediate, but not nearly as intense. Still red, but not burning. After taking it I feel like I was in a sauna. Very interesting, and I like the way I feel afterward, so I will continue to take half a few times a week.

初めて飲んだ時15分位したら首から下がどんどん真っ赤になってきてびっくりしました！アレルギー反応かと。それが全身に広がっていきましたが、湿疹が出る様子はなく体がぽかぼかして血行が良くなったのがわかりました。ダイエットを初めて立ちくらみがひどくなってしまったので、改善されるのを期待しています！
