Maybe it is my age...
Perhaps it is my age (59). Or perhaps it is my health (diabetic). I had no idea how much I would benefit from this. I can actually work a full 40 hour week, and then put in 10 hours overtime! I am amazed and I purchased several bottles as gifts for family who needs it as much as I did.


Both my husband and I have been taking this for a few months and love it! Our 23 year old son tried it and absolutely loves the way he feels. Seriously don’t go a day without it.

I’m feeling 20 years younger
I have to say this product has made significant improvements to my energy, mental focus and memory. It took a solid 2 weeks to notice a definite improvement that is steady and all day long. I am remembering things like picking up something for my daughter asked me to get for her after work, I’ve gotten nearly my whole house organized and sorted out, and I’m doing those little every day chores without dreading them like before such as vacuuming and tossing that load of laundry in the was...Here’s the real kicker...I haven’t told my husband what I started taking and for the last few weeks he keeps asking “Who are you???” lol...I’ve also been losing weight with much more ease than before. I am also taking garcinia cambocia, green coffee bean extract and raspberry ketones...so I know some of my energy spikes are from the green coffee bean but my overall energy from waking to bedtime is an even steady reliable rate.

I went from not being able to sleep to sleeping like a log
I have been taking this for 2 months, I have noticed changes in my BMI, I went from not being able to sleep to sleeping like a log and don’t know if this has anything to do with it, but suddenly my creativity is back. I was working out daily seemingly to no avail prior to using this product. I intend to keep using this to see how good it gets...

49 And It Worked For Me
I had read articles about the human anti-aging trials starting this year so I took a chance on this. I’m 49 and I don’t know about feeling 20 again, but I definitely feel like I’m 35 again. I started lifting weights again this past year (former college wrestler an coach) and had consigned myself to being too old to lift like I did in my mid thirties. So I cut back on my workout routines, instead of doing 16 sets per muscle group, I had to cut back to 6-12 sets per muscle group. I figured at this age (going on 50) doing anything was good. Within 1 week of taking the NIAGEN® I somehow had the energy to pump 16 sets. I don’t come home tired from work and only work out on weekend or have tp slam caffeine pills and energy boosters to get a workout in. I feel good everyday. I did my research and from what I gather this product works better for older people, the younger body builders didn’t report much of anything. But from my understanding this product helps protect the brain in contact sports, so I don’t want to turn off everyone young. I have 3 sons that play football and if this product was cheaper I would put them on it.

It doesn't make you super human but just a bit better
On the second bottle and have noticed improved energy slightly. I also have had gout and this has helped quite a bit in not having attacks. It appears the anti inflammation claims are real. It doesn't make you super human but just a bit better. After a day of hard skiing the next day is not so difficult, the soreness is nominal and recovery is faster.

I feel better taking this - nothing scientific but it has made me feel sharper mentally. No Benjamin Button effect so far but hoping!

WOW !!!
This product has been described by some as the 'fountain of youth' & it turned out to be just that for me. After 3 days, totally got rid of the CFS symptoms. First time in years I wasn't tired all the time. Only downside: after one week of taking it, I wasn't able to sleep much. As I seemed to suffering no ill effects in the daytime, I continued to take it. Then I crashed. However, after discontinuing the product for 2 days, was able to re-start at a lower dosage, & have had no further problems.
I'm hoping to be able to take this for the forseeable future. Makes me fee lat least 20 years younger.

Does make an impact
Did pretty much what was expected. The actual impact of the product wasn't "felt" until I missed a few days of taking it. Supplements work differently for different people. I found it useful.

I will buy again


A Game Changer.
Report after the first week. Incredible spike in smooth energy and focus. There appears to be a marked decrease in aches and pains. At 65 years old, this is a game changer. So far, no jitters. Unfortunately no weight loss yet. I'll give an update in a few weeks.

C. Martinez

Item delivered on time, was as described, great customer service. I would Definitely buy again and I would recommend to my friends

I love this stuff
I've been using this for 6 months. This helps me deal with a full time job and 8 hours of night school. Before taking this I was in a daze during the week. Now I have an even amount of energy throughout each day.


Good price, good stuff.
No adverse side effects for me or my 69 year old father. This stuff stimulates me to dream a lot. That's not why I take it but it is a side effect that I've noticed. We take two pills a day with our first meal. I usually have about 2-3 dreams a night now when before it was rare for me to dream so I know this definitely does something. It comes in a brown glass bottle to keep light from degrading the pills.

I was told that I look like a teenager twice this year already
My husband and I have been taking this for a year, now. His grey facial hair has been now turning dark again. He is 56. I noticed a change in my skin right away, since skin cells regenerate quickly. I was told that I look like a teenager twice this year already, and I am 47. This is part of a regimen of healthy eating and exercise, but I have noticed that this product works well, if you stick with it long term. I am a medical professional and am not easily swayed by gimmicks, but I believe this one to be sound. We will continue to take this.


I can confirm that this NIAGEN does work as well ...
I can confirm that this NIAGEN does work as well as Elysium Basis I used before that , I tried other cheaper ones without success so this is a winner , 2 capsules = 250mg last for 1 month

One of the few noticeable supplements
This is one of my all time favorite supplements. I feel a little boost of energy and awareness within 20 minutes of my morning dose upon waking. I take other supplements but this is the one I notice when taking and am aware when I run out. Coupled with PQQ it can't be beat!


Worked for us
Actually has boosted energy for my husband and me. The results make it worth the price.

It worked immediately in boosting my energy levels as well as improving short term memory

Len McCall

Seems like the real thing, from my experience
All the effects are consistent with what the literature has lead me to expect.

Bella Lou

Increased energy.
I was skeptical of the claims but thought I would give this a try. I can't tolerate the recommended dose so take only half. If I d I have increased energy, no mid-day naps and I feel like my concentration has improved. It has not improved my quality of sleep. I'll continue on with this.
