Product should have a warning label! 😂🙏
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.

Too potent! READ THIS POST 📬 BEFORE BUYING!
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!

Vitamin B3: Eggs are a good source of vitamin B3 as well as protein. Feb 8, 2019, update - I took my vitamin with liquid protein and didn't get any immediate symptoms. 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!

Flush is real 🥴
Good product. I'm a first time niacin user and have been taking this for the last 4 days. Must be taken with food and drink plenty of water to avoid upset stomach. The reviews really had me scared. I do experience a flush- burning and itching sensation like a sunburn- uncomfortable but it's not unbearable. Taken once a day. I have anxiety so its best to take at bedtime to sleep through symptoms for me. Product does what it says it does.

Effective Supplement with Noticeable Effects
I've been incorporating this supplement into my daily routine for the past month, aiming to support my overall health. The capsules are easy to swallow, and I appreciate that they're non-GMO and gluten-free. One thing to note is the flushing effect. About 20 minutes after taking a capsule, I experience a warm sensation and redness, especially on my face and neck. It's a bit uncomfortable but subsides within an hour. I've found that taking it with food helps minimize this reaction. Despite the flush, I've noticed improved energy levels and a general sense of well-being since starting this supplement. It's a potent product, so I recommend starting with a lower dose to assess your tolerance. Overall, it's an effective supplement, but be prepared for the flushing effect. If you're sensitive to this, you might consider a flush-free alternative.

I have read about the flush that niacin (nicotinic acid) gives the body and thought I was prepared, how wrong I was. Nothing I read prepared me at all for the intense flush this product gave me and what a flush it was. I decided to take one tablet before going on my evening walk and within minutes of taking it I started to feel the flush coming on and it ramped up exponentially. Within 15 minutes I felt like I was cooking, my nerves were tingling all over my body and my mouth felt dry yet it wasn’t. It wasn’t a bad experience but it wasn’t a nice one either. I was glad to be walking in the cool evening because it helped cool me down. The worse of the flush lasted about 45min and seemed to completely settle after about a hour to a hour and a half. One thing I experienced that I found really strange was how clear my thinking became and the increased self awareness of my own body, it seemed a bit surreal. Think carefully before you buy this product, do your homework; every body is different and you may not cope with the intense flush this product gives. That said, would I buy it again? Yes I would.

届いた時に中の内蓋がすでに半分剥がれていて、カプセルも真っ二つに割れて粉が出ていた

It really makes you flush. I know some people find it painful int heir stomach, but for me it's a sauna. If you do it semi regularly I think it gives me more clarity, though I'd take that with a pinch of salt.

某女優さんの雑誌のインタビューで、「ナイアシン」が睡眠の質を良くすると言っていたので、こちらを購入してみた。たしかに他の方が言っているように、接種後、体が熱くなる感はあります。ただ寝る寸前に飲むと、熱くなる感を感じず、熟睡できるようになりました。

Usually not mean in buying pills on line but problems in supply chains globally have restricted supply of nicotinic acid in Australia . These tables gave the nicotinic acid flush reaction so they feel like the real deal . Great price as well 25% of the local nicotinic acids prices
