Major Niacin Flush should be expected.
5 Stars
Major Niacin Flush should be expected.
Niacin will give you a definite flush unless you get a controlled release. The standard Niacin is supposed to be more effective so I figured I could handle it. Lets just say that it was an extreme experience that started within 20 minutes of ingesting the vitamin and lasted for approximately 3 uncomfortable hours. My entire face was red and inflamed as well as my chest, arms and hands. You can see by the photos that my fingers on the tips turned very white and the the rest of the hand was RED. The bottom of my hands turned extremely white but my entire arm from the top down to the wrists were RED. I felt like my skin was on fire, as if I had a severe sunburn and then took a hot shower. My entire body including my legs itched. Luckily I planned ahead and took the Niacin on my day off. Had I taken this and went to work, I would not have been able to concentrate at all for 3 hours of my day. I did take this on a full stomach as I do with all my vitamins.
