  • Promotes a healthy lipid balance



  • Time-released over 6 to 8 hours



  • Patented and proven formula


Niacin is great for maintaining a healthy lipid balance in the body. But for many people, the dosage levels required for significant benefit can cause an unpleasant red "flushing" effect. Swanson Ultra has tackled that problem with Sustained Release Niacin tablets, which release niacin into the system gradually over 6 to 8 hours, minimizing the flushing effect.

Sustained Release Niacin 4.9 5 28 38
Non-flush Niacin! This is an excellent way of taking Niacin each day. Instead of the stuff labelled as non-flushing, this is a time released product. It hasn't caused me to show any blushing associated with Niacin, and it works! I've read the experts say the non-flush products don't give you what you take them for. This solves the problem! November 2, 2014
Best Purchase I tried other brands which would often cause flushing shortly after taking. This formula very seldom causes any flushing and is consistently reliable. August 7, 2014
This really works! The non-flush products are a waste of money. This product delivers what we need and the sustained release has prevented any flushing for me! November 17, 2013
No flushing This is a great value from Swanson. I do not experience any flushing from the Niacin, so sustained release actually works for me. I have been taking this for months and plan to continue. October 22, 2013
Its ok I take it with food & get some flush from the sustained release, not bad just for a minute or two. My blood tests are on par with the no-flush so no noticeable improvement. October 14, 2013
Great Product After my doctor suggested I start taking niacin, I first tried another brand which caused flushing and burning.So I switched to this one. No more problems. It seems to be very effective too. Thanks Swanson! July 7, 2013
It works At my doctor's recommendation I started taking Niacin. Many brands weren't satisfactory because of "dumping" after a few hours with severe flushing. I have never had this product ""dump" nor had any unpleasant side effects. July 5, 2013
excellent product Niacin is supposed to help one's help in several ways. I have been using that particular Swanson product for years and it has fulfilled all expectations. June 2, 2013
Sustained Release Niacin Take this product to help keep my system strong and healthy May 28, 2013
great product i had giben up taking niacin,because i disliked very much the side effects [rush].but with sustained reléase niacin.no unpleasant rush. great product May 12, 2013
Swansons Ultra sustained release niacin Have'nt started using this yet, but I heard a N.D. say it was good to get a sustained release niacin to use, and Swanson's had a good price on it, so I'm going to give it a try. March 27, 2013
No flush This Niacin does it's job without causing flushing or hot flashes. March 24, 2013
No Flush with this Niacin This is the best Niacin you can buy. No flush, effective and inexpensive. A great product. February 24, 2013
No Flushing! None! Swanson Ultra has solved the flushing and itching problem and this product is truly effective. Yes, it works and you will be happy with the results. I have recommended it to my friends who have had uncomfortable flushing experiences with regular niacin. There is no niacin product that I know of on the market that compares in quality, price and performance to Swanson Ultra! February 14, 2013
good flushing affect, top quality product. January 23, 2013
A little early to tell I'm trying the timed release. I don't get the niacin flush anymore. But it's a little early to tell if its doing any good. but I trust Swanson vitamins and believe their products are good. January 13, 2013
Comparable to High Price Brand You can pay 20 times more for timed release niacin that is no more effective than the Swanson brand. Believe me, I have tried both! September 19, 2012
No Side Effects I have tried other High Profile Niacin products and find this to be the smoothest as far as flushing . August 9, 2012
Works well with no flushing Provides everything I want from Niacin with no flushing. April 22, 2012
Best NO Flush Niacin This is the best Nicontinic Acid That I have found.I do not flush taking Swansons Brand Niacin.I've tryed other brands that were Time Released but, there was always FLUSHING. April 8, 2012
Regular Purchase The sustained time-release is great - and, I do not get the 'niacin flush' from this product. I purchase this regularly. April 1, 2012
Worth the money I have found that Niamax works better than flush-free Niacin. February 16, 2011
5 Stars for all! I was looking for a sustained-release Niacin in 500mg online and found Swanson. What a great buy this supplement is! Great price and fast shipping! I will definitely buy from Swanson for future supplement and vitamin purchases! October 13, 2010
good Niacin Seems to dissolve better than the time release Niacin I buy from the pharmacy. Little flushing May 7, 2010
really helped I'm really satified with the results of taking Niacin. May 5, 2010
