"The first few weeks of taking them I felt just tiny pricks of itchiness in my face, which lasted for about 15 minutes. But then this past week suddenly there was intense heat and itching all over my body and extremities. It was almost unbearable. It lasted about half hour. I was shocked. I decided to try again the next day and it was the same again. I have not taken it since. I never did take more than one pill each time."
"Just a heads up. . This is a great product, However ,You will need to slowly adjust to it. . start by taking 1 cap until you get use to the flushing ,itchy skin that last about 1 hour . . slowly build up your tolerance to this Niacin . . So don't do a full dose until you slowly build up. ."
"First time taking Dr. Berg's Niacin, which warns of a flushing sensation, so I took 2 (instead of the 4 making a single serving). Flushing sensation came, and it was almost overwhelming- felt it along my neckline, and forehead. Lasted maybe an hour. Same for next day, taking 2 at a time, except flushing sensation was on different parts of the body: back of neck, top of forearms. Continued taking 2 for a week, then moved up to 3 afterward. Flushing sensation continued, but again, in different parts of the body, usually neck area, and head (back of head, top of head, cheeks, but different areas each time). Week 3 moved up to all 4 for a serving size. I barely notice the flushing now. It was overwhelming on week one, especially the first day, but now, it's almost a welcoming feeling, knowing it's working."
"Great product! I always drank water as recommended and never experienced the niacin flush that can happen! Loving it!"
"Took Dr. Berg's flushing niacin (started low at 125mg capsules to build tolerance) for a few weeks—flush is noticeable but quick and not too intense once adjusted. Feeling more energized, better mood, and circulation seems improved. Quality product, no issues—great for heart/energy support. Highly recommend starting slow!"
"I didn't like the feeling these gave me at first, but I've come to love it. I feel "cleansed"."
"Love it, helps me so much."
"My husband tried it once and had flushing and itchy arms, can’t get him to use it again, anything help??"
"I took for five days My heart started racing."
"I trust Dr. Berg's products as a reliable source to find supplements. His webinars give great background information of the correct type to take for one's issue. I recommend his supplements and webinars."
