Life changing

Posted by iHerb Customer on December 17 2017 | Verified Purchase

Amazing. It took just over a week too get rid of the muscle tension in my back. I have been in constant pain for so long it felt normal. I'm feeling more relaxed &I not so anxious. My wife has now started using it so I'm hoping it benefits her as well. Make sure you have a decent meal before taking it the first couple of times. I don't experience the hot prickly anymore.

Thanks for your feedback!

Allergic reaction

Posted by iHerb Customer on October 26 2017 | Verified Purchase

I have taken plenty of B3 niacin supplements previously - sometimes up to 3000mg to assist with anxiety. However this particular product caused a significant reaction (whole body redness and violent shivering) - my mother was also hospitalized with anaphylaxis due to this vitamin. Use with caution.

Thanks for your feedback!

Fantastic effective!
