Best Answer:  This is immediate release,I have been taking 1000 mg per day to help raise my HDL and have been very pleased with the results.If you have not been taking niacin before you will have to start at a lower dosage, perhaps 100-200 mg per day and build up over a 2-3 month duration.You will experience some flushing but this will pass adjust your dosage accordingly until you get to a comfortable level.Do not use the "extended release" or "no flush type" if you wish to improve your HDL they are useless for this purpose in my opinion.
I am not a doctor but this is what has worked for me.

Best Answer:  To lessen the flushing take a baby aspirin appx 15-30 minutes before taking. Also, I always took mine prior to going to sleep and was usually out before any flushing :)

Best Answer:  This question could be considered three questions:

1. Yes, this Niacin can be considered crystalline, but the term crystalline is vague at best, and does not seem to be a well-defined term. The real question is: does this Niacin cause flushing, and the answer seems to be YES.

2. Reducing flushing: some of the other answers do a very good job of describing the benefits of the flush. The doctors that have encouraged me to use Niacin have been in agreement that one should start out with small dosage (50 to 100 mg) and allow your body to acclimate to the flush. As you can tolerate it, increase the dosage. My wife can handle only 100 mg at a time. I am up to 1,000 mg twice a day, which is the target my doctor set for me.

3. The term "crystalline" does not appear on any of the labels of Niacin that I have purchased over the last 15 years. What I look for on the label is a warning or caution that it "may cause flushing". What I DON'T want to see is "time release". Most times you will see one of these, but sometimes neither is present, and you have to guess. I usually won't buy a product where the contents are not clearly presented.

If the product is really Niacin, the label should state that it contains nicotinic acid.

Products labelled as "no-flush" niacin generally contain no nicotinic acid. The main component in these products is inositol hexanicotinate.
