  • 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.

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 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!

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.

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!

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.

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.

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.

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.

Rated 5 out of 5 by from No flush This Niacin does it's job without causing flushing or hot flashes.

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 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.
