The flushing is verry nice, and relaxing, also good for sleep.
Great for People who Bruise

I am 70 years old and have a tendency to bruise on my hands and lower arms. I can take one (1) B3 Niacin per day and the bruises will be gone in just a few days. Individuals may have different reactions to it. I just get real red all over, others may itch with it. I would recommend not to use it on an empty stomach for the first time.

I love Life Extension's products because of its purity. This supplement contains nothing but pure Niacin, gelatin and vegetable stearate. The flush is strong and nice. I am not experiencing flush any more as I did at the beginning. I would recommend to start with lower doses like 50-100 mg and drinking a lot of water if ones are vulnerable to flush effects. However I liked it when I was getting flush, the feeling was okay, sometimes itchy, I knew that it works at least. I just want say to not get discouraged by side effects, you can avoid it or weaken it. Your body will get used to it. Also 500 mg seems to be a lot so I may decrease dose to 250 or 100 mg after this container. High doses of Niacin may affect your liver functioning. Consult it with your doctor if you have any liver impairments.

Haven't used it long enough to know if it is having desired effect, but it certainly brings on a flush, which it must do to have an effect on the arteries. Like this company's products, but glad to get it here so I can get free shipping!
