Nutricost Niacin (Vitamin B3) 500mg, 240 Capsules (2 Bottles) - Niacin Flush

I made the mistake of not researching this product before buying. I based my decision on what everybody was writing. After I got the product and I took it I got the flushing and everything as expected but actually, I thought it was much worse than expected. For me, I got all the flushing symptoms worse than expected. It made me feel so dizzy, weak muscles, and thirsty.YES, you get a massive burning feel, worse than I've ever had! Strangely it relaxed all my muscles, made feel like pooping, which I did, rather well, just a healthy poop. The shock on my system made me tired. Do it before bedtime.If you are going to try this product, pls do your research! I always do, but this time I didn't which is dangerous!

I'm still waiting. It's been almost 45 mins. Maybe the key to taking it is taking it with HIGH protein. The flush did come about an hour later. It started with light head tingling and then a stronger burning sensation. Then it became a sunburn like flush throughout my face. It lasts about 40 mins. No body flush.So 2/10/2019 I took another one. At first I thought oh strange nothing. An hour later comes along, head tingling head flush, face flush, massive body flush, muscle weakness, I had to run to the bathroom, loss of bowels (sat on the toilet - i was quite surprised needless to say - cleaned me out well!), weakness was so bad i think i was on the verge of passing out, shut my eyes and leaned against the wall. I got the chills. I was so weak and tired I laid down. Ovaries and tubes felt like they were throbbing and on fire!!! I'm curled up in the fetal position in pain praying it ends. I'm covered in blankets to keep me warm. I guess I fall asleep for about 20 mins. About an hour after it started it all subsided and stopped. I'm very thirsty. I had just got done breakfast (2 eggs and about an ounce of salami) and a little bit of greens protein drink. Two days ago, I had a very potent greens drink with maaca, cocao powder, morninga powder, and homemade kefir. I only got the head flush. After today, I'd need to be super brave to take another tablet. Definitely don't take it before or during work LOL OMG!

Gents and Ladies, this is 500 mg of pure niacin. That is a gigantic amount. If you have never taken niacin before, do NOT start with this dosage. You need to start on 100 mg per dose for a month, and ramp up to 250 mg, then 500 mg, etc. Your body has to get used to this in order to minimize the flushing side effect. As you can see from other reviews, if you take 500 mg without having taken niacin before, you're going to wish you hadn't.I have taken niacin for years to help raise my HDL numbers, and it does raise them, although not a ton. I take 1000 mg twice a day, and I still get a decent flush on each dose, but that's after years of getting used to it. Ramp up, do not start at high doses.

This product literally ruined my day. I am a nurse and have taken different types of niacin with some flushing in the past. This product was on a whole new level…I took the tablet and about 20 minutes later the skin on my hands and face began to get really hot. It got more and more hot until I had actual welts over my entire body. I laid down because my heart was pounding extremely hard at a fast rate. Anything touching my skin really hurt, but I couldn’t move from being dizzy. I felt like I was going to heave a heart attack or pass out for about an hour. This continued but suddenly I started feeling very sick to my stomach and barely made it to the bathroom before my intestines released everything I’ve ever eaten. I slowly limped back to bed. My headache is intense and the room is spinning. I lay down again and now I am so cold I start shivering. The shivering turns into full body jerks that I cannot control. I was looking for something online to tell me I didn’t need to go to the hospital, but now I can’t even hold my phone from these intense spasms ripping through my body. After another 45 minutes laying there wondering if I’m dying and saying a few prayers it passed. The rest of the day I have been cold, my skin is sensitive, and mildly dizzy, and my head hurts.Somehow, I still think niacin is healthy, but I would highly recommend someone brand new to flushing niacin start at a much lower dose. 500mg felt like I was going to die. I am so glad I didn’t take 2. My husband was terrified and kept want to call for an ambulance or “do” something to help. Thank God I wasn’t working today.

Purchased this in hopes that it would improve my grandpa's cognitive function and it works! He's been on it for about 4 weeks now and is showing signs of improvement. It creates a flushing for about 30min-1hour. Overall, he feels better when taking it.

Nutricost consistently ranks high on the supplement tracking app I use, and this product is no exception. It checks most of the boxes when it comes to safety and quality. The inactive ingredients are clean, and everything is made in the USA in a cGMP-certified, third-party-audited facility. It’s also NSF certified, which adds another level of trust.I appreciate the level of testing behind this—third-party verified, raw ingredient tested, purity tested, and screened for heavy metals. The only things missing are lot-specific testing and public batch COAs, but those are nice-to-haves rather than dealbreakers.The formula is free from fillers, dyes, and GMOs, which is important to me. While the founder doesn’t have a medical or scientific doctorate, that’s a minor point considering the product stands on solid quality and transparency. Overall, this is a reliable supplement from a brand I feel good about using.This can or will make you FLUSH -- do your research as it can be uncomfortable. This has positive effects on cholesterol
