NutricostNiacin (Vitamin B3) 500mg, 240 Capsules - with Flushing, Non-GMO, Gluten Free

So, I am on a journey to cleanse my by body of toxins from all the junk food I’ve eaten over the years and wanting to change to a healthier lifestyle and came across these pills for ‘flushing toxins’ among a couple other vitamins. I take a pill while heating up some nachos. After about 10-15 minutes I became a bit itchy and felt some prickly/heated areas on my body. Look in the mirror and ears are dark red and forehead bright red. I go outside to get some fresh air and the flushing started…. Immediately went to Amazon to see reviews and it made me panic, instantly (lol).I sincerely thought I was having an allergic reaction, my heart started beating so fast and I became ‘light’ all over my body. As I started to pray (I never do that 😂) I began crunching a Zyrtec!! Shaky knees at this point. I realized it was me who was making my heart race and just needed to calm down! After what felt like an hour I was a little calmed down and the heat was slightly less my arms started to get red and blanching in areas I decided to jump in the shower.After the shower I noticed all the red had subsided from my face, arms and neck. My face actually looked refreshed! While I still feel a sense of heightened-ness I enjoy the refreshed look of my facial skin in the mirror.Lastly, I do think this high of dose should come with a clear warning of the flushing and still a little nervous if I’ll have any additional side effects the rest of today.

This version that is nicotinic acid (not niacinamide/flush-free) is the "flushing" version of niacin/vitamin b3. 500mg niacin per capsule. The first couple times I took one capsule in the evening after dinner, before bed, and felt zero flushing, which is fine and I'm sure my body absorbed and used the niacin. A day or two later I took one upon waking, on an empty stomach, and within just a couple minutes felt a very intense whole-body "burning" sensation head to toe, for at least an hour or more, which I was prepared for, having taken this vitamin many years ago. So, it is a legitimate product and it is definitely potent, real nicotinic acid, with real health benefits. Do your research, and don't take TOO much at a time, as apparently very large doses in the thousands of milligrams may cause issues, but consult a doctor. The "burning" sensation is completely normal and mine was very intense and lasted for over an hour, and even lingered in my feet after waking up from a nap a couple hours later, do not panic.

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! Unless you are truly suffering from vitamin D3 this product is dangerously potent!FYI for people who aren't good at researching:Vitamin B3 (nicotinic acid, nicotinamide)Vitamin B3 is also known as niacin.

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!
