The real no flushing niacin.
I had tried a few other slow release no flushing niacin products, but I often had really bad flushing once or twice a week sometimes to the point that it felt like my skin was on fire. Endur-acin is the real deal. Absolutely no flushing most of the time and the few times I had flushing it was very minor, even at the same dosage. Plus it is real Nicotinic Acid which is the form that helps control cholesterol.

No Flushing - Yet
I had previously taken a 500mg slo-release Niacin version. I didn’t make the association at first but after about 3-4 days I experienced a severe hot flash. My skin became reddened and I was so uncomfortable I had to go outside because the outdoor temp was in the 50s. However even outside when the sun hit me I thought my skin was going to burn off. Thought I was turning into a vampire.So I’ve been trying this at 250mg dosage starting at every other day. No issues. Now I’m at every day - no issues. So my 4 star rating is for easy to swallow, low cost, no severe hot flash. If later on there has been an actual impact on my cholesterol I’d give this 5 stars. My cholesterol isn’t high on an absolute basis but it was suggested to me that at my age I might benefit from a statin. I’m not fond of that idea, I find that losing weight and keeping it at a good level has more impact, which I’ve done. If this Niacin improves my cholesterol even more then I’ll be more than satisfied. If necessary I could increase it to 2 a day to equal 500mg but I’m not going to risk the severe hot flash.
