I take this niacin for the flush effect, as I did not read that it was no flush with extended release, I just crush them and swallow with water to get niacin flush. no taste , just dry when crushed. I buy most supplements from NOW and quality is alway top notch. the energy rush from flush feels great

Very high quality. This is my second purchase and will continue to add Niacin to my rejuvenation protocol. The size of the bottle is very adequate for its price and it seems that the active ingredient is present to a very high percentage within each pill. I have been a very loyal customer to Now products for over 10 years now and will continue to do so, so long that they maintain their high standards.

I've used niacin over 30 years and this particular brand has been consistently good quality . I really enjoy the flush it gives and feel the beneficial effect on my nervous system of the vasodilation effect every morning. My doctor was baffled by how low my cholesterol and triglycerides are and how balanced my metabolism is. Excellent value for money at this potency

This is Niacin as Nicotinic Acid. The tablet is a high quality slow release form. Nicotinic Acid is the form of Niacin that will cause flushing and the form that will help lower total cholesterol, the bad LDL cholestserol and Triglycerides. It will raise the good HDL cholesterol. It will help reduce inflammation of the liver. It helps preserve memory and brain cell health. It is potent. I often flush with in about 1 hour if I do not take it with food or ibuprofen.

The flush from this product is amazing, totally red, itchy and hot (then cold and goose-bumpy when the flush subsides). I LOVE it for micro-vessel dilation and flush. I would say that this product isn't for those faint of heart, as the effect can be intense, especially if a build up of histamines! Such a great internal beauty supplement

good quality supplement with many benefits for the bode, niacin flush can lower stress,and blood preasure and check medical guidance for being assured, the size of package is not costy and recommended to take, as mentioned it effects the nervous system positively despite temporary skin irritation and you can reduce Skin irritation by taking it after healthy meal&drinking some water, it has some taste after the flush effect but its fine with me

Beware the niacin flush! Niacin is anti aging and super for ameliorating heart disease. This product is nicotinic acid and does super things for you, you just need to get over the feeling of the flush, which is quite something, but only lasts a few days if you keep taking the product. Scientifically proven for reducing cholesterol.

Good quality niacin, it does give you a good niacin flush but i have learned to appreciate it more, its nice before sleep helps with energy. Take niacin after melatonin for extra nervous system support. It has good potency effect. Good big size package. I like the ingredients, no time released stuff.

These Niacin give the flush and, therefore, are the best form of niacin to purchase. I understand that the flush is uncomfortable for some people, but if you have anxiety or bi polar depression then these are the only ones that work for that. The flush free versions will not have any effect on your depression and anxiety. I have had tremendous benefits for my own depression and anxiety thanks to these. NOW, always come up with quality products, and this is no exception. 5 stars.
