Rated 5 out of 5 by from like the flush some don' like the flush associated with niacin, but i do. i can tell right away that something is happening. most supplements that you take you wonder if it's doing anything. not so with niacin that isn't modified to be time release and anti flush.

Rated 5 out of 5 by from NIACIN WITH TRAINING WHEELS Personally, I take the Big Boy Niacin - - - the 500 mg. capsule I buy from Swanson Health Products. I'm sure you all know about the 'Niacin Flush' one gets after taking a sufficient dose of Niacin. I like the flush. I'm used to it. Heck, I've been taking Niacin in 500 mg. capsules for several decades. I value my 'Niacin Flush.' One of my daughters was asking me about the value of my 'Niacin Flush' when she observed my 'just-got-back-from-a-sunny-day-at-the-beach-look.' When I told her about its overall values, from circulation to skin and everything else, she said she wanted to give it a try, but with one caveat. She didn't want the full blast, red-and-tingly-all-over, major league Niacin Flush. . . . At least not to start with. Kinda like gingerly sticking your foot into the surf before wading in when the water is cold at the beach. I told her about this 100 mg. Niacin tablet. I told her how one tablet may or may not give her a bit of a flush, depending on what she had recently eaten. This way, she could get used to a wee bit of a flush at first, then increase her dosage to 2 tablets to see what a little bigger flush was like, and then go on up to 3 tablets, or more. There is no telling how many milligrams will give an individual a flush of any size --- small, medium, or all-over-large; however, it has been my own personal experience that about 3 tablets (= 300 mg.) starts to get the job done. I like to take 500 mg. of Niacin with my main batch of nutritional supplements daily. Let's me know I'm alive, so to speak. Hey, works for me.

Rated 4 out of 5 by from controlable dose and no flushing I have tried other forms of B-3 and find this to be a good all around. On days I feel that I need the energy boost and the added circulation I can increase the dose and because there is no flushing and tingly irritation at this dosage and formulation I can take them as needed without any discomfort and can split a 500-1000 mg dosage throughout the day as opposed to all at once.

Rated 5 out of 5 by from Best fom to support healthy lipid panel My doctor recommended basic niacin to support a healthy lipid panel, not flush-free or sustained release. I tried this one, starting with one tablet and quickly building up to 5 per day, but the reaction was very unpleasant, so I had to go back to one. My doctor said I rushed it and must build up slowly. So, over the past 6 months, I've built up to 3 per day, two with breakfast and one with dinner. I get very little flushing with a meal. I hope within a year to increase to 5 per day, but already I'm getting good results. To support heart health I also take Norwegian Cod Liver Oil Lemon Lime, which is very good tasting and sold here as item NAT065. Plus, 3 daily of Buffered C with Bioflavonoids, item SW944. And on my doctor's recommendation to support healthy arteries and lipids, I also take 2x L-Lysine SWU452, 2x L-Proline SWU450, 2x L-Arginine SWU457, 2x TMG SWU466, and 2x Plant Sterols SWU503. I'm happy Swanson's carries all of these at good prices, and my latest test results are excellent. I'm trying to do everything right, but no question a big part of my improvement came from cutting sugars and carbs in my diet by about 85%. Basically, I eliminated them, except for a small amount of cheating. Kal Pure Stevia Extract Powder had been a big help KL504.

Rated 5 out of 5 by from Tingling Even though Niacin gives me a tingling sensation I know that is is helping me with circulation. The benefits outweigh the quickly gone tingling.

Rated 1 out of 5 by from No better than a sugar pill I was taking 3X100mg tablets per meal and never got a flush. I switched to another brand and the flush is so strong that I have to cut up the tablet to the level of 50mg! My husband got the same reaction.

Rated 5 out of 5 by from Very good value This product gives you 250 tabs, which is a great value for the price. It is so cheap, and gives you way over your daily intake per serving. I take it twice a day, and it helps!

Rated 4 out of 5 by from CRUSH or CHEW before swallowing When I swallowed these pills whole, I got the flushing for about 1 in 5 or more pills I took. I took them on an empty stomach and felt the effect only in a couple of hours, when I started to eat. (That is if the effect did happen.). HOWEVER, when I began to chew the tablets prior to swallowing them, the flushing effect happened every time and within just a few minutes. This proves that tablets are a bad way to deliver nutrients. I can't tell about the deeper effects niacin has on me, but at least the flushing effects is there.

Rated 5 out of 5 by from great, flush effect means it works It's great, came quickly, lot of pills in that bottle for the price, love it. Has flushing effect, that's how you know it's working.

Rated 5 out of 5 by from better dosage for me I take niacin on a regular basis and require the regular form--not the flush free--for my particular needs. I discovered that taking one 100mg tablets several times a day helps to avoid the major flush I was getting from the 500 mg capsules.

Rated 5 out of 5 by from Flush! Love the flushing effect. Haven't noticed much else, but the cost is great as well as the quality. Been using it 1x a week so far.

Rated 5 out of 5 by from B vitamin I just wanted to add some additional niacin for my skin and diet.

Rated 5 out of 5 by from Flushing at 300mg I took these pills for a week, originally 100mg doses. Week 2 I tried 200mg and still felt nothing. Today was my first day on week 3 at 300mg and the flush was intense and strong! Within 35 minutes of taking it, my skin was red and very itchy. I am pleased to finally find my dosage for this, I may use a pill cutter and try 250mg to see if its less intense. I will be buying this again!!

Rated 2 out of 5 by from great buy Just be sure to follow directions on the side of the bottle: do not take on an empty stomach. I did, and ended up with the skin flushing and tingling which they warned about.....

Rated 1 out of 5 by from No Flush Have never got a flush from this Niacin. For 100mg these are about eight times larger than other Nician that I have used. 90% of the time I got a flush from my other 100mg Nician. I have not got a flush from the Swanson. The benifits from Nician come from the flush.

Rated 5 out of 5 by from Excellent Buy Did not notice the flush effect that most speak of with this product. It was a slight moment only. Nothing like I read about. Good value and worth taking.
Date published: 2010-02-10
Rated 1 out of 5 by from Disappointed The flush is usually noticeable with 250 mg of niacin from a different brand. However, 300 mg from this product does not produce a flush. I've had good results from Swanson products but I'm unhappy with this product.
Date published: 2010-02-06
Rated 5 out of 5 by from I like this product Stronger doses of Niacin gave me so much of a flush that I was extremely uncomfortable. With this product, I still get flush but it is not uncomfortable. For me the right dosage at the right price. Can't beat that! Just wish it came in capsule form...

Rated 2 out of 5 by from Not totally satisfied I was advised by my doctor that regular niacin was better and that the flushing of the skin is what you want. I've used other niacins ( not the "No Flush " variety) which in 100 mg doses produced that flushed feeling. I can take 300 mg of the swanson with very little reaction. Not sure what to make of this.

Rated 5 out of 5 by from Works for me I get a flush with this niacin but much prefer it over the time-release capsules.

Rated 1 out of 5 by from Disappointing For the first time, I am disappointed with a Swanson product. Niacin is one of the nutritional supplements you can actually feel working (that's the "flush" you've heard about). With other in-expensive niacin supplements I've taken, the flush is noticeable, but with this Swanson niacin, there is no flush at all, leaving me to wonder why...
