Great product
I used Slo-niacin 750mg daily for 4 months at dinner time, two years ago. It helped me loose weight. But it did create heavy flushing for me. While taking it I felt I could not drink alcohol, because it made the flushing worse. When I eat healthy, the flushing felt kind of nice. Also sometimes i would get dizzy when working out. So for me slo-niacin could only be temporary. I was missing the feeling and benefits of slo-niacin, so I tried smaller doses of both niacin and nicotinamide. I tried 100mg, 200mg, and 300mg of each. For me, with no particular health issues at the moment, I felt having 200mg nicotinamide at breakfast and 200mg nicotinamide at dinner felt great. I had less appetite, and craved healhtier foods more. Also it had a calming effect. I was able to drink a few beers a week with nicotinamide at this does and not feel any negative effects (for me that 5 beers total in 1 week, 1-2 per day, three days a week). So for me personally, nicotinamide is good for overall health. I like the skin benefits, mood calming, the feeling of liking healthier foods more, and appetite suppressant effects. In the near future I will likely reduce my 400mg per day to 100mg a day to see if it still has a similar effect, and then likely will move it up to 200mg per day. I try to just take the amount I need, and no more. Because taking too much of a supplement can deplete other nutrients.

Very effective supplement
This is a wonder pill for reducing pain and inflammation in joints. Of course they can't say that on the bottle or in their advertising. It was recommended by a well known online doctor so I thought I would try it. Low dose 3 x daily. After only a week my knee pain disappeared after a year of limping and misery. I can't guarantee that it will work for your problem but it's worth a try. I am no doctor but I can tell you it worked wonders for me. I'm walking normally for the first time in two years. No I wasn't paid to say this!

Satisfied with my purchase.
I gave this product five stars because it really seems to work. First this item arrived on time and was packaged well. The supplement looks like small white pills and are very easy to swallow. I took my first niacinamide pill during the afternoon with a couple of other supplements and I felt fine. I learned somewhere that niacinamide can help with sleep so I actually took my next pill the next night and I do not know if it was the supplement but I was sleepy at around 10 and I usually stay up till 2am. This could be because of an alteration in my schedule but I'm going to try this again because it's always nice to sleep well! I am happy that I experience no side effects with this supplement and that it seems to be doing what it is supposed to. Overall, I am very satisfied with this purchase- it took me a while to choose which brand I'd buy from but I am happy I chose this brand. If I had any criticism it would be the extra ingredients but considering I only take one a day and the pills are so small, it's not the worse for me. Thank you Source Naturals for the product and I hope my review could be of any help.

Arthritis or morning stiffness from RA
I have terrible hand arthritis, esp in my fingers and lower thumb joints. I started on Boron, which helps keep the pain at bay, but it did nothing for the morning stiffness. I'd wake up after a nap or from nighttime sleep barely able to move my fingers. Heaven forbid I needed to open a top or jar. After researching the boron, I a medical article on niacinamide: "The effect of niacinamide on osteoarthritis: a pilot study" Google arthritis+niacinamide and you should discover many articles. But the dosage should start off low and work your way up. I started off with 100 mg several times a day up until I took about 10 a day. When I've skipped, the morning stiffness comes back in a day or two. You want to spread out the dose and build up. Smaller is better as it has a short half life. I'm going to try upping it to 250 mg several times a day, since I've had so much improvement. (I'm not ready to give up dairy as I hear this could be the cause. Love my cheese!) I'm just surprised the my RA hadn't suggested this. He knows I'm taking it, now, and how much, so I know that's not an issue. But this should be first defense before taking any drugs. I take no painkillers for arthritis now. This stuff works.

Great price for this vitamin
This is a great price for this vitamin, certainly far cheaper than what’s sold in a big grocery and drugstore chains. I’ve been using this brand for many years now. I can’t remember why I started, but it’s hardly going to cause me any harm and has no side effects. I love a bargain price, and this has it.
