Swanson Premium Niacin Reviews

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Niacin is rated 4.6 out of 5 by 57.
Rated 3 out of 5 by from disappointing I really like the "real" Niacin, as I like the flush which comes with it from time to time. I was surprised about the low price of the Swanson Niacin, and thought Niacin is Niacin, can't go wrong. O.K, I was wrong, there is no flush at all with 500mg of Swanson Niacin, where already 250mg of another brand gave quite a big reaction. I have to take 3 times the dosage with 750 mg to get a mild reaction, if any at all. Disappointing.... I have no explanation for this, maybe the magnesium stearate, which is one ingredient, is weakening the effect. I will go back to the other brand.

Rated 5 out of 5 by from Thank you I was not really understanding what "flash niacin" means when I took it first time. In 20 minutes I turned as red as a tomato from scalp to toes,but the feeling wasn't too uncomfortable.Then I red the reviews and someone was suggesting taking it before bed,so I did the next night and just slept through very well. I did notice the fresher look of my skin in the morning. Thank you for advise!

Rated 5 out of 5 by from Niacin with a full flush I needed niacin that provided the "flush" and this is it. Most of the niacin I found in stores was the flush-free type. Seems to work great, but prepare to feel this in your face.

Rated 5 out of 5 by from Very Good My doctor advised me to take straight Niacin, not the flush free. This is 500Mg. and very convenient to take. I have been using this for years, it does what I want it to

Rated 5 out of 5 by from Niacin This is an excellent product. It really keeps me in a good mood and helps me to be stress free. Niacin stands for nice and that is exactly what it does

Rated 3 out of 5 by from I tried plain Niacin In the past, I used "flush-free' niacin. I thought I would try the non flush-free to save a dollar or two. I do not like the feeling of the plain variety and will return to the flush-free version on my next order.

Rated 5 out of 5 by from Read don't go by my stars Ok I am going to write a contradictory review from the 5 star rating. The reason being is because I know what people are looking for in their niacin supplement. The Flush! If you are looking for a niacin supplement that you know you are getting what you pay for by the amount of flush, then this is the product for you. If you can't stand the flush effect and are like me that if too much flush makes you sick then I do not recommend this supplement.

Rated 5 out of 5 by from BIG BOY NIACIN If you are a regular Niacin user, you are familiar with the 'Niacin Flush,' which is what happens when the Niacin dilates the capillaries, most prevalent in the skin / face / head, and one gets pink / red and feels the warmth. I consider a Good Niacin Flush when one experiences their Niacin Flush throughout their body, and down their arms and legs. You look like you just came in from an afternoon out in the sun. The Niacin Flush generally comes on around 10 to 15 minutes after taking a sufficient dosage of Niacin on an empty stomach. It generally lasts for 15 minutes, or so. If one takes Niacin with or after a meal, or with dairy products, the Niacin Flush is often weaker, takes longer to materialize, and has a shorter duration. If one drinks some coffee around the time they take their Niacin, the Niacin Flush is generally more intense. Many people find that if their Niacin Flush is too intense, drinking a glass of milk or eating a cup, or so, of yogurt or cottage cheese can scale the Niacin Flush back. In addition to all the things you can read on Swanson's website about the benefits of Niacin promoting carbohydrate metabolism, thereby helping to supply the entire body with energy, and supporting cardiovascular function (healthy heart and good cholesterol / triglyceride --- lipid levels), Niacin OBVIOUSLY creates greater circulation, which is essential to life itself for every cell in the body. The Niacin Flush is evidence / proof of this. That is what I am seeking when I take Niacin. . . . The experience of improved and efficient circulation delivering nutrients and carrying away wastes throughout every part of my body. I have been using approximately this 500 mg. potency of Niacin for about 40 years. I am used to the Niacin Flush, I welcome it, and I like it. If you are new to Niacin, I strongly recommend that you do NOT start with this 500 mg. potency in one capsule. My suggestion would be to begin with the 100 mg. Niacin, and work your way up to 3 or 4 or 5 tablets, getting used to the Niacin Flush along the way. Then when you want the Big-Boy Niacin Flush on a regular basis, graduate to this 500 mg. Niacin capsule. Swanson's Niacin products are excellent quality. They work. They are very reasonably priced. My suggestion is to avoid 'flush-free' Niacin where you cannot see the results. What's the fun in that?!!!

Rated 5 out of 5 by from Love the Tingly Flush! I buy it for the niacin flush, which I enjoy. Although my skin doesn't turn pinker on just 500 mg it is enough to relax into feeling my capillaries open to better blood flow. If you've never taken niacin before and are new to the tingling it can feel startling. You may want to start with 250 mg.

Rated 5 out of 5 by from Good flush! You want the niacin flush then this is what you want. I chew on a capsule so it opens up then swallow with a little water. Good quality niacin!! So much niacin is non-flush these days and a bit hard to find the flushing type niacin

Rated 5 out of 5 by from Very effective This Niacin is high quality and very potent. It produced the flush it should when I first started taking it. After a few days the flush all but disappeared.

Rated 2 out of 5 by from Not Good for Me! I had been taking niacinimide for quite some time with no problems. On a whim, I chose to use this straight niacin and was quickly sorry I did. Taking 2500 mg. at once was no laughing matter. I became red as a beet all over and itched unbelievably for at least 36 hours! Itching continued even beyond that time but not so intensely. Needless to say, I didn't take it again. If you've taken niacin before, I imagine this is a good product. It just wasn't good for me! I've never had trouble with any of Swanson's products before and will continue to buy from them.
