Let’s face it, we are all aging. Whether we are old or young, aging is happening by the minute. This process has always been thought of as unavoidable and inevitable. But what if it wasn’t? True, we cannot stop time; but what if we could ease the effects time has on our bodies, our energy levels, and our minds? Niagen has this ability, and that is why Niagen by HPN is the holy grail of anti-aging and cellular health supplementation. Niagen increases NAD levels by 33% in humans with just one dosage! In a recent study at Harvard University conducted by Dr. David Sinclair, increasing NAD+ levels was shown to be the key to slowing down and reversing markers of aging in our cells and our bodies.
Dr. Sinclair’s work demonstrated increasing NAD+ levels is the key to restoring the communication between our mitochondria and nucleus in every cell. This optimizes energy production and reduced free radical production on a body wide scale. Additionally, earlier research by the anti-aging pioneer Dr Leonard Guarente demonstrated that a special protein group called “sirtuins” are largely responsible for slowing down the aging in our cells. Activating these sirtuins became a huge focus in research. What researchers discovered was a missing link, the fuel for the sirtuins. This fuel is known as NAD+ which is short for Nicotinamide Adenine Dinucleotide. With the discovery and release of N(r) we can now increase NAD+ Levels to maximize cellular health, optimize mitochondrial function, and fuel sirtuin activity.
This results in every cell of our body operating stronger and more efficiently immediately and on an ongoing basis. The effects of this are nothing short of amazing. Imagine feeling more energy, increased alertness, and amplified mental clarity all day, every day! N(r) can deliver all of this and more! Try N(r) today and begin to experience all of the benefits everyone is raving about.

N(r) Niagen is the greatest breakthrough in natural supplementation since Creatine. In an industry ripe with BS, N(r) Niagen is an absolute blue chip, a product built on real science and university clinical data. N(r) Niagen only contains one ingredient, Niagen. This ingredient, scientifically known as Nicotinamide Riboside, is structurally a member of the B-Vitamin family. Niagen has a host of benefits including brain health, muscle endurance, metabolism, and anti-aging; but they all come back to one simple fact; Niagen increases the level of NAD+ coenzyme in our cells.

WHAT’S the Difference between N(r) and no flush niacen?
Many who are more versed in science will immediate wonder what makes Niagen different from Niacin or plain nicotinamide. The best analogy here is to consider what makes Gold different from your American credit card or a bank check in a third world country with no electricity. Gold will be very easy to use and will give you a lot of bargaining power, while the credit card and check will be next to useless. Our bodies inability to efficiently handle Niacin is well documented and expressed with a sensation many of you have experienced, known as the “Niacin Flush”. Even with No Flush Niacin, the compound is very limited in its ability to increase NAD+ levels and increase mitochondrial function. As far as nicotinamide, we cannot achieve our intended benefits without the Nicotinamide Riboside being absorbed and used in an cohesive manner. In fact the differences are so unique that Niagen has multiple United States patents granted for its production and different benefits.

Fat is burned in our bodies by the Mitochondria. Stored bodyfat is released into the blood stream as fatty acid. These fatty acids then enter the Mitochondria to be “burned” aka turned into ATP, our body’s usable energy source. N(r) Niagen by HPN naturally super charges your mitochondria to make your fat burning machine stronger and more powerful than ever before. Combined with diet and exercise you will be on your way to leaner, tighter, and more toned physique. Research pertaining to N(r) and NAD Levels has been done at the following prestigious universities and institutions:

N(R) NIAGEN has no known negative side effects. It can only improve your body’s energy levels and overall health.

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 want to go a day without it.

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.

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 and coach) and had consigned myself to being to old to lift like I did even 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 8 - 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 out 16 sets. I don't come home tired from work and only work out on weekends or have to slam caffeine pills and energy boosters to get a workout in. I feel good every day. I did my research and from what I gather this product works better for older people, the young 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.

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....

Nr for all around health
High Performance Nutrition (HPN) - product Nr is definitely one of my top 5 supplements. I can tell when I don't use it. When I do use it I have good energy, mental clarity and feel all around better in all aspects including well being. Give HPN Nr a try and I promise you won't be disappointed. It's also safe for sport and helps your metabolism.

Niagen is revolutionary
great supplement! Niagen is really a breakthrough in anti-aging research. It is revitalizing, effective for fighting off fatigue, neuroprotection, and improving muscular endurance.

The research continues to pour out - a recent study even showed that one week of treatment with a Niagen type supplement restored mitochondrial health and muscle health markers of a 22 month old mouse to that a 6 month old mouse. For humans, this would be the equivalent of making a 80 year old man's muscule's function as that of a 20 year old !! I plan on giving this to my elderly father as soon as possible

Why I take HPN NR
I'm not a muscle head, but I do want to live forever. I'm not going to have my head dunked in liquid nitrogen in a bid for immortality, I simply do a lot of research and Nicotinamide Riboside represents a major breakthrough in cutting-edge anti-aging supplements. I'm fifty-eight years-old, but people are often amazed that I don't look it. Tiger Fitness is a reliable source of this new product and are eager to please. When I run out of my NR supply, I'm going right back to them. "Service-with-a-smile" means a lot to me, so they have my business for as long as I live- and that's gonna be a looong time!

Magic Beans!
Niagen - To me, this is a wonder supplement. A few days after I started taking it, I just felt GOOD! Sustained energy levels throughout my day, and an overall healthy and alert feeling. It helps me at work, and it helps me stay fresh and energized throughout the day and night. As a busy professional working 12 hour days, then trying to put in a good workout and have energy for my kids and family at the end of the day, this stuff is great. The best part is, I have had a genetic predisposition for high cholesterol. Diet and exercise are not enough for me, and I am forced to take a statin to control it. When I added this to my regimen, I ended up having the best blood work I can remember after 2 bottles (along with proper workouts and nutrition). My cholesterol dropped from over 200 to 133 and allowed me to cut down on the dosage of statin I need to control my cholesterol. I know that this product helped me achieve that goal. This is my personal favorite of all HPN supplements.

Niagen - the antiaging miracle
amazing supplement! HPN's Niagen is really a revolutionary breakthrough in anti-aging research. In my opinion, it may be no less than "the fountain of youth" in pill form. It is revitalizing, effective for fighting off fatigue and improving muscular endurance, and is even neuroprotective.

The research continues to pour out - a recent study even showed that one week of treatment with a Niagen type supplement restored mitochondrial health and muscle health markers of a 22 month old mouse to that a 6 month old mouse. For humans, this would be the equivalent of making a 80 year old man's muscles function like that of a 20 year old !! I plan on giving this to both of my elderly parents as soon as possible

Would stacking N(r) with Acetyl-L-Carnitine theoretically enhance it's benefits on the mitochondria? I am on my fourth day using this product with no other changes, and weight is dropping consistently after just starting to gain on my 5.5 week of reverse dieting.
Joseph C on Oct 16, 2013
BEST ANSWER: Absolutely! N(r) will supercharge the mitochondria, and the Acetyl-Carnitine will deliver more fatty acid to the mitochondria! This is a fantastic combo!
Can this Niagen product be taken by someone who is not an athlete for the purported benefits of the product such as the metabolic benefits of glucose metabolism and weight loss and not just for head injuries with athletes?
Todd R on Jul 5, 2013
BEST ANSWER: Hey Todd, N(r) can ABSOLUTELY be taken by anyone wanting to improve their overall health. N(r)'s ability to elevate NAD+ in our bodies in the crux of all that this product can do. The research for Anti-Aging, Muscle Endurance, and Metabolism (glucose control/decreased fat gain) is OUTSTANDING and applies to far more than just athletes! Try it for yourself! N(r) is a life-long supplement, no hype, just real research!

BEST ANSWER: I don;t find this to be the case. Take one of these a day, and after a few weeks (maybe two), you'll feel more'll feel like your mental retention and and access have kicked up a notch.
I am currently on a high dose Niacin(nicotinic acid). Will I benefit from Niagen supplementation ?
Rich N on Aug 12, 2013
BEST ANSWER: Targeting NAD metabolism for therapeutic purposes opens a host of exciting possibilities - nicotinamide riboside and nicotinic acid both beneficially enhance NAD levels but in slightly different ways. To properly answer this question I would need to understand the reason Rich is currently taking the high dose of Niacin - if the answer relates to lowering serum triglyceride levels then Niacin would be my choice.
Is it safe for a 21 year old to take?
A shopper on Jun 13, 2016
BEST ANSWER: yes, anyone over the age of 21 should be fine.
do you send to australia?
A shopper on May 11, 2014
BEST ANSWER: yes we do.
Can Niagen tm be taken post exercise on a empty stomach. Such as a situation like nutritional timing, perhaps after along run or after resistance training. As I see it, it might fit into the science of Niagen tm. What do you think?

Best Regards,
Jim C on Jan 29, 2014
BEST ANSWER: It's a B vitiam so I took it first thing in the morning for energy. But I think it builds up levels in the cells of your body so anytime as long as it is daily would probably work.


To use N(r), take 2 capsules daily upon waking or immediately prior to consuming first meal. It is not necessary to take N(r) with a meal. After each bottle, we recommend discontinuing usage for 3 days for maximum effectiveness.
