Review after taking and reading other reviews
I read reviews after I bought this while waiting for it to come in and I was worried about taking this because people where saying they had to go into the hospital over it. I'm taking this trying to lower my cholesterol levels and I was worried about the flushing but honestly it just feels like a sunburn (but not sensitive with touch like a normal sunburn) on face, ears, nose, arms, belly and in my case other sensitive areas. The flush only last 30 mins to an hour on me after that I'm fine. I do notice slight nausea after taking it during flush but not like I'm going to get sick from it. Sometimes I get a weird aftertaste that last awhile. The capsule is about the size of extra strength tylenol.

Reliable and cheaper without sacrificing quality.
NOW makes reliable supplements and I am an avid flusher with Niacin and I have been using NOW brand regularly for 15 years. They are reasonably priced and usually cheaper and more reliable than most competitors. There are some really good companies in the nutritional supplementation industry.

I know they work!
Some days I take these and I'm out of commission for at least 10 mins, due to all the itching n scratching. Some days it barely itches when taking. I'm going to assume that those days of intense itching is the days when I need it most. I usually feel be/er on days that I take them. But I do not take them on a regular basis.Also NOW brand are ny most dependable brand when purchasing supplements.

Disappointing Experience with Intense Side Effects
I bought NOW Foods Niacin 500 mg hoping to support my heart health, but my experience was far from positive. After taking just one 500 mg capsule on an empty stomach, I started feeling intense itching all over my body within 30 minutesโit was unbearable and lasted for over an hour. This is clearly the โniacin flushโ mentioned in reviews, but I wasnโt prepared for how severe it would be, especially spreading to my shoulders, back, and even my arms. On top of that, I also felt bloated and uncomfortable in my stomach, which made me hesitant to take it again.I understand niacin can cause flushing, but for a first-time user like me, the 500 mg dose felt way too high right out of the gate. The product description doesnโt emphasize enough how intense these side effects can be for beginners, and thereโs no guidance on starting with a lower dose. Iโve since learned I shouldโve taken it with food or started with a much smaller amount, but that information wasnโt clear on the bottle or packaging.While NOW Foods is a reputable brand, this product wasnโt a good fit for me due to the overwhelming side effects. Iโm returning it and looking for a lower-dose or flush-free alternative. If youโre sensitive or new to niacin, Iโd recommend skipping this or consulting a doctor firstโotherwise, you might end up as uncomfortable as I did.โPros:โข Reputable brand, made in a GMP facility.โข Vegetarian capsules, free of common allergens.Cons:โข Extremely high 500 mg dose caused severe itching (flush) and bloating.โข No clear instructions for beginners or sensitive users.โข Side effects outweighed any potential benefits for me.UPDATE: Flush became worse during warm weather conditions and caused hypotension and become unconscious for few minutes. Very scary. Be careful if you are new to this.

Easy to swallow capsule versus lozenges...
Niacin (Vitamin B-3) 500 mg, Essential B-Group Vitamin. This is an easy to swallow capsule. I assume it is close to the bioavailability of the lozenges.Niacin causes flushing. The first time I ever took it, I turned bright red. Start slowly and know what to expect.You can start with smaller doses.NOW Foods is a good company with numerous endorsements for products and company.

Great for Restless Leg Syndrome
I have always had problems with Restless leg syndrome throughout my life. I started taking this daily for something different and noticed that when I lay down at night, no more RLS. I researched this and it says there are studies that it helps with circulation and with RLS. I wish I would have known that decades ago. Works great, eat with food or better yet, take it a couple of hours before bedtime. He's, you will get the flush from this, but it gets better the longer you take it.

Flushing niacin from a trusted brand
Flushing niacin. NOW Foods Supplements is a well known brand for me. I trust their products. This niacin is a flushing variety, meaning you will most likely get the red, hot, possibly itchy skin. For me, this is exactly what I was looking for. 1 capsule is 1 serving. Capsule is normal sized and easy to swallow. Flushing ensues approximately 20 minutes after ingesting. I can't take these every day, so I think this bottle should last me a good while.

Too strong for me
This dose is just too high for me. About 20 minutes after taking it once, I got itchy all over and had what looked like hives from scalp to feet. That lasted a little over an hour and then subsided. I did have great energy the next day. I don't think I had an actual allergice reaction, just an intense "niacin flush" experience. I have chosen a different product with a much, much lower dosage per tablet now.
