      Major flushing, dizziness!

      •  
      from Halesite NY on 1/22/2019
      I reordered, what I thought was the same product (Vit B3 500mg caps), which I had been taking for about 6 or more months with no side effects. I took one capsule from a new bottle and immediately felt sick, dizzy, was wobbley, very red, flushed, runny nose for about 60-90 minutes. Some forms of the B3 Niacin have cause similar, though less dramatic symptoms over the years. I thought I was getting the same formula I had previosly from Life Extension, but thought wrong.

      Make sure you pay attention to dosage, which I did not! Start out small and work up to Vitamin B3 Niacin by Life Extension. Great as it is, too much flush can be really awful to get through, but feels great once the flush passes.

      Pros

      Brings on a strong flush.

      Cons

      Too high a dosage.

      I need niacin on a daily basis, Vitamin B3 Niacin by Life Extension helps with my heart murmur I have had all my life, keeps my valves clean and my blood clean because of it's flushing qualities. The types that are "non-flushing" aren't giving you the full benefit of it!!!

      Pros

      It flushes well!!!!

      Cons

      I have no dislikes about Vitamin B3 Niacin.

      Product was too strong for me so I have to take 1/2 capsule at a time so I do not get as strong of a "niacin flush". Wish I would have gotten a lower mg/capsule product.
