I just started taking it so I can't say how it will affect me. I think it will be good for my blood vessels.But I have to warn people with normal\low blood pressure - please take it only with a good meal. First time I took it with a little meal and beside experiencing hot flush and my skin going red and tingly, my blood pressure dropped when I stood up and I fainted! Please be careful! Take it with a good oily\protein meal or at least do not stand up for a 20-30 minutes while it takes effect.

The dosage for B3, Niacin, at 100 mg is a high. Units of 25mg to 50 mg would be better. Leaving the choice to take more than one at your discretion.Great price. I will cut them in half.Harvard: "The Recommended Dietary Allowance (RDA) for adults 19+ years is 16 mg NE for men, 14 mg NE for women.Webmd: "Maximum daily intake for adults of all ages: 35 milligrams daily. Most people can get the amount of niacin they need by eating a healthy diet."My doctor, who recommends the supplement and also takes it does doses of 50mg which they say is 3x the recommended daily dose.

Niacin is known for its potential benefits for heart health and cholesterol support. However, some individuals may experience the "niacin flush" as a side effect. Overall, 21st Century Niacin tablets are a trustworthy choice for those seeking an affordable niacin supplement.
I can’t say how well these worked or the long term effects of taking them everyday. It is probably important to supplement our diet with things like this.Unfortunately I just couldn’t get past the smell! I don’t know if I got a bad lot or not but I don’t think it was that. It’s just a really funky offputting smell which made me dread taking them. I didn’t notice a taste though. I would try to find a different brand that wouldn’t smell like that, or find another way to take this before I would purchase again.In terms of a product it was a generous amount, size was small and easy to swallow and the price point was excellent. That’s why I’m not giving just 1 star.
I originally ordered this in May 2022 and most recently re-ordered February 2023. The tablets have changed. They used to have a light coating that made them easier to swallow. Now it is just a dry, chalky tablet with no outer coating which makes it get stuck in the back of my throat while trying to swallow. Still works. Just won't be re-ordering this brand, again. Too bad I have to suffer through 110 tablets of this chalk before I do.
