Nutricost Vitamin B3 Niacin Powder

I bought the previous version of this and it was great, I loved it!

Then I bought a bottle again and it tasted completely different. I wanted to find out why, I emailed support, they had me lookup the lot numbers of the current and previous bottle, maybe hoping I would have thrown the other one away, but I still had it, so I supplied them with the lot numbers. Their response was:

"Thanks for your email! I have an update stating that sometimes we switch vendors to ensure the same retail price but always verify the ingredient is the same specifications for the potency. This product and Lot is just an updated version. Please let me know if you have any questions!"

Then I asked, how can there be different potencies for a product that you claim is 100% niacin? Isn't 100% always the same potency? And they stopped responding. I prodded back about two more times and absolute silence. The silence is very incriminating.

That's too bad, I used to really like them, I'll have to find a new seller. And since I can't trust them to not lie about the purity of their niacin, I can't trust them about any of their other products anymore, I guess it's time to try other brands.

Excellent product and works as researched if you have done your home work. Unfortunately some reviewers do not understand how to gradually introduce niacin into their daily use and would do themselves good by doing this research before use. Please do yourself a big favor and understand the flushing that is first experienced is normal. Once you introduce it on a regular basis the flushing goes away for the most part but understand the flushing is a very good thing. That is why you start with a very low dose so that your body doesn't totally freak out and you are not caught off guard emotionally. Try researching flushing from niacin at orthomelecular.org or Dr. Saul on youtube and or his book on Niacin ,and there are many more resources available.. Once again, this product does what it is suppose to do and I've been using if for just over 3 years now.

This stuff is awful. Immediately broke out in rash. Got light headed, nearly passed out and lost my breath. Stomach cramps. Avoid!!!

I had to call Paramedics for the first time in my 60 years on Earth! The dosage says 1mg (it has a tiny measuring cup). I have occasionally supplemented with various niacin's over the decades and never had a strong reaction. I put one dose in my caffeine and sugar free 8oz coffee (after having just finished another 8oz drink, and had about a third of it when I had the only strong reaction to Niacin in my life. I had itching skin and my face, neck turned beet red and my arms, stomach, chest and part of my legs developed large red spots and my heart raced. My it scared me when my face and neck turned almost purple so the Paramedics watched my vitals for a while until they confirmed that my heart rhythm and BP were safe. I took an aspirin as advised by them and the internet to aid in clearing it from my system. I tried a second time a few days later with only about 1/8th of 1 mg. I still had a classic "strong" reaction of some splotchy red patches on my arms and chest, flushed face and neck.

Be aware, the Niacin produce some sides affects, and this product is not eligible for a return.
