Rated 5 out of 5 by FCDLE Mitochondria & Cell Energy Go Big
After taking Niagen for one and one half years, I can submit an objective review for this product and it's effect on "my body." Did this product increase my energy level while exercising and day to day living? Yes it did. However, my increase in energy was gradual (six to eight months). My exercise capacity was very significant at eight months both in terms of running and resistance training. I was so pleased with the results I began combing it with resveratrol and pterostilbene.

Rated 1 out of 5 by lean2me Zilch...
Ordered 3 bottles to give the supplement a fair amount of time to demonstrate its effectiveness. Unfortunately it didn't make the least bit of difference and failed to a very large degree to live up to the advanced hype. Overall quite disappointing and a waste of money.

Rated 3 out of 5 by Bilskey Not sure of the value
I didn't notice any profound or even mediocre difference after taking this product. Expensive..yes! May not be giving it enough time or maybe the manufacturers over-promised and under-delivered.

No harm - no foul. How does one really assess the benefit of a supplement?

Rated 5 out of 5 by kalel33 Great find
I have studied about the health of the mitochondria in details. everything start with the cell and the health of the DNA is also linked to the Mito. This product is very good. take it early in the morning on empty stomach. I usually take it with organic non gmo coffee and melt a table spoon of organic coconut oil in my cup of coffee. You will feel a difference

Rated 4 out of 5 by Susied44 Expensive but Works
I read about this form of niacin in Life Extension magazine. I was interested in trying it out after reading about all of the purported benefits. The energy boost is definitely there. I have had a major issue with "crashing" as the afternoon goes on, and that has greatly diminished. It would be helpful if the price was more reasonable. I will continue to buy this product as it has been so beneficial, but please Mr. Swanson, put it on sale???

Rated 3 out of 5 by West Noticed a moderate difference
I did feel a bit of an energy boost. Just not a $47 dollar a bottle boost.

Rated 5 out of 5 by pointlessnickname Worth the Price
I am very impressed with this product. It has increased my energy and sense of well-being. Prior to using this I generally awoke with a feeling a malaise that took stimulants and a few hours to shake before I was up to doing anything. Now if I was 80 years old that might not be so startling but at 31 there was no way I should feel like this.
I have and education in nutrition and exercise and am physically active to a great degree and my nutrition is very detailed and thought out. Despite this something was missing. Was it this? I do not know. What I do know is the improvement is tangible and worth the price of the product.
People complain about the price but the product actually works. Add up the money you have spent on supplements that did not do a darn thing and the amount can be staggering if you have been at this for a while. Sure a bottle of vitamin C is cheaper as are most products but do they make an actual improvement in your day to day life?
The price pales in comparison to what people pay for their cellular service and cable bills every month and despite what many tell themselves those products do not really improve your life, at least in my opinion.

Rated 5 out of 5 by Enthusiast Works better than similar product by Thorne
I purchased this, which really seems to work. I also purchased the similar product by Thorne, which does not seem to work.
I don't understand why there would be a difference.
In any case, I really like this and I get a clear boost from it. I will continue to use it, for sure.
The science behind this product is exceptionally strong. Look at recent publications by Sinclair and others.

Rated 5 out of 5 by AlfromCal Amazing Supplement
I think everyone should try this stuff! The research is pretty much conclusive that it has amazing potential, taking it is pretty much a no brainer. It has been shown to have great effects on mitochondrial function... I can actually FEEL this, as I never seem to fatigue while I'm taking it, andI blast right through my normal 4-5pm lull. I will be staying on it forever!

Rated 5 out of 5 by la0508cynthiamccoy One of the best supplements ever
I am so happy I found this. I have been looking for nicotinamide riboside for several years since I read several articles about it in scientific journals. I am 64, and have had a problem with energy hitting a wall by late afternoon. Just one of these capsules in the morning on arising helps me to maintain energy all day, and still feel I have reserves to carry on. Along with rhodiola rosea it is one of my very favorite supplements ever. I think it is way over-priced, however. The reason why is that only one company is licensed to sell it, and the compound, although naturally occurring in tiny quantities in milk and brewer's yeast, is patented. Still, it is so good that I will not stop using it no matter what. Instead of 2 per day, I take only one and give my husband one. This works for me.

Rated 5 out of 5 by la0508 Expensive, but worth it.
This is a great vitamin for energy, but that's not all it does. Nicotinamide riboside is present in tiny quantities in milk and brewer's yeast. Because this supplement is so expensive (but worthwhile), instead of 2 a day as the label recommends, I use 1 a day and give 1 to my husband. Really thrilled to see Swanson carries it.
