  • 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.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Sustained Release Niacin is rated 4.9 out of 5 by 41.
Rated 5 out of 5 by from Great Supplement This is the best Niacin that I have ever taken. Very seldom do I have any side effects and if I do, it last only a few minutes. As long as Swanson carries it, I will purchase it.

Rated 5 out of 5 by from quite surprised I take once in the morning...No flushing at all Will continute to use
Date published: 2015-10-23
Rated 5 out of 5 by from 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!
Date published: 2014-11-03
Rated 5 out of 5 by from 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.
Date published: 2014-08-07
Rated 5 out of 5 by from 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!
Date published: 2013-11-18
Rated 5 out of 5 by from 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.
Date published: 2013-10-22
Rated 4 out of 5 by from 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.
Date published: 2013-10-14
Rated 5 out of 5 by from 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!
Date published: 2013-07-07
Rated 5 out of 5 by from 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.
Date published: 2013-07-06
Rated 5 out of 5 by from 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.

Date published: 2013-05-13
Rated 4 out of 5 by from 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.
Date published: 2013-03-28
Rated 5 out of 5 by from No flush This Niacin does it's job without causing flushing or hot flashes.
Date published: 2013-03-24
Rated 5 out of 5 by from No Flush with this Niacin This is the best Niacin you can buy. No flush, effective and inexpensive. A great product.
Date published: 2013-02-25
Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from good flushing affect, top quality product.
Date published: 2013-01-23
Rated 5 out of 5 by from 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.
Date published: 2013-01-13
Rated 5 out of 5 by from 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!
Date published: 2012-09-19
Rated 5 out of 5 by from No Side Effects I have tried other High Profile Niacin products and find this to be the smoothest as far as flushing .
Date published: 2012-08-09
Rated 5 out of 5 by from Works well with no flushing Provides everything I want from Niacin with no flushing.
Date published: 2012-04-23
Rated 5 out of 5 by from 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.
Date published: 2012-04-09
Rated 5 out of 5 by from Regular Purchase The sustained time-release is great - and, I do not get the 'niacin flush' from this product. I purchase this regularly.
Date published: 2012-04-01
Rated 5 out of 5 by from Worth the money I have found that Niamax works better than flush-free Niacin.
Date published: 2011-02-16
Rated 5 out of 5 by from 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!
