This is a good product, niacin is great stuff and Carlson Labs is a great brand but I am going to get the Bluebonnet 100 mg caps next time so that I'm taking in less fillers with my niacin. I wish Carlson's would do a niacin capsule!
Junk or a bad bottle

I have taken as many as nine of these at a time no flush what so ever and these are not flush free. My wife has tried the same amount many times too and nothing. When we take GNC 500 mg we feel a strong flush I am not sure if this was a bad bottle or what but IHerb if you monitor these reviews my wife feels a refund is in order for the amount of business we provide.

If you take enough, you get the flush to know it's working. I started at one every night, then after a few days increased to two. I had a small flush the first night at this dose, so I continued it for a few more nights, then increased to three. I flushed the first night, but no big deal- it only lasted about an hour and was quite an experience. Continue this schedule to get to your desired dose! It's good stuff!

Be prepared for some flushing, so start slowly. I'm still at 50mg after 3 weeks because of the flushing.

These seem to work well.
Works for Sleeping

I read that Niacin can help you sleep. I knew it was good for other things but did not know that it may help you sleep.
