HPN NAD3 NAD+ Booster for Cellular Energy, 312 mg, 30 Veggie Capsules | NAD3 formula supports cellular energy and healthy aging; 312 mg per serving and a nicotinamide riboside alternative.

​I purchased the HPN NAD3 after doing quite a bit of research on NAD+ precursors, and I have been taking it consistently for over a month now as part of my daily health regimen. ​The results have been fantastic. The most noticeable change is my daily energy level—I feel much more sustained energy throughout the day, and that afternoon slump is completely gone. My focus and mental clarity have also improved noticeably. ​It has integrated perfectly into my structured routine, and given how good I feel, I will definitely continue with this exact protocol long-term. Highly recommend to anyone looking for a premium, effective cellular health supplement!

So far i have been taking these less than a month but so far so good. I have energy and I feel really upity up and about and im feeling young again. I totally recommend so far

These were amazing for energy! I accomplished so much in just the 2 weeks I took them - I’m quite devastated I have to stop. They caused daily migraines that pain relievers weren’t effective for. I tried to wait for the side effect to subside, but I already get migraines so they aren’t ideal for ME. I recommend trying them if you sincerely want energy that doesn’t cause jitters or an afternoon crash. Worst case? You lose some money. Best? Your life will be so much more productive. I can’t stress how lazy I am and how effective these vitamins were for me.

Great product !

I am a 65 year old female who has had cancer twice, and have been in remission from stage 4 metastatic cancer for 11 years, due in part I believe to a regimen of supplements including resveratrol, quercetin, Vitamin C, Vitamin D3, and many others. I also walk 3 miles per day, and have tried to avoid sugar and refined carbs for much of that time. Throughout the years I have been following anti-aging and anti-cancer research, as a curious layperson. I have explored writings and videos by David Sinclair of Harvard, Leonard Guarente of MIT, and others, leading me to the recent reports on the postulated benefits to humans of NAD precursor, Nicotinimide Riboside. Leonard Guarente himself takes it, according to his Elyseum website. I started taking the recommended dose in early February, 2015, and can report some positive results, although I believe the dosage level is critical and probably varies widely, depending on one’s age and health status. My experience has been that the prescribed dose of 250 mg. is simply too much. It revved me up, but the rebound effect was very noticeable--exhaustion. A suitable analogy might be constantly gunning and red-lining one’s old, inefficient engine. So I cut back to a half dose every other day. Much better. I still feel energetic--and optimistic--but am not completely exhausted hours later after the initial burst of energy has waned. It would certainly seem logical that younger, healthy, and/or athletic folks already have sufficient amounts of NAD, so they probably wouldn't notice much if any improvement from supplementation with NR. However, old folks have NAD deficiency as a result of aging, and probably see a much greater benefit from supplementation with NR. which increases NAD. I am guessing that most of the folks reporting little or no benefit from NR are either younger & healthy and have plenty of NAD; or, perhaps are taking far more than they need, producing some sort of negative hormesis-like response; or are not taking complementary doses of resveratrol, or other pterostilbenes, which operate in tandem with NAD as a substrate to influence anti-aging sirtuins. An update: I am now 68 and still taking NR from various makers, who add various components along with NR (all Niagen based) and at various dosages.. The 250 mg. dose is now my standard, however, and I no longer have the exhaustion effect. I don't know why, but it is gone and I am feeling great. I always take resveratrol daily, and many other supplements as noted above. I am also considering the other NAD precursor which is starting to become available, nicotinamide mononucleotide, but the price has got to come down significantly and some major advantage over NR demonstrated. Another possible effect from taking the 250 mg. NR dose is noteworthy: my fasting blood sugar is now running in the 60's and 70's regularly, but I do not feel bad. I have been doing a form of intermittent fasting for some time, but even when I have a regular meal, a few hours later my fasting glucose is back in the 60's & 70's. I test it daily. This may in fact serve as a long-term indicator of the continued efficacy of NR. I have never had fasting glucose levels this low, before taking 250 mg. of NR daily.

Im 64, i took one capsule before breakfast and soon after i couldnt stay awake and slept for almost 2 hrs and then just lay there unable be fully awake enough to get up for another hour, a few hours later i started to feel very brief pains not in but near joint areas randomly around my body. Dont know what to make of all this, so far nothing i can call positive has happened, ive only taken the one capsule i wont be taking a second one today, ill have to decided about taking one again tomorrow. I can only give it 3 stars at this point till I learn more. I do like the new bottle though, the way you twist the top and the clear part opens up with a hole to let the capsules out, its a unique design.

I am 58 years old, in good health and work out and run regularly. As I continue to get older, I noticed that I just wasn't a sharp as I had been, multi tasking seemed harder and my focus and concentration wasn't what it used to be. My memory was also getting worse. I started taking this product back when it was Niagen and saw some great improvements. The improvements were subtle but continuous. Better memory and better concentration at work. Recently I changed to NAD3 and I'm now on my second bottle and have seen even better improvements. The best way I can explain it is my mental fog has gone away. At work, I have much more focus and get more done. My memory is better and I'm not searching for my words. I take the recommended dose of 2 pills first thing when I wake up in the morning. I love all the health and anti-aging benefits that is happening in the background, but even more I love the way I feel sharp again. Great product!

It's Great! The package is Easy to dispense with just a twist to open twist to close!! Healthy for you too!

I have only tried this and one other brand that was 333 mg. I like the one that is 300 mg. On the forums concerning niagen its really only recommended for 35 years plus and many don't notice differences until in their 50's, because their bodies are producing adquate sirts, ie sirt 1 3 6, etc. I'm 54 with arthritis, chronic fatigue and other issues and noticed immediate results in energy but also in arthritic pain and joint issues. And had moderate weight loss. Going to stick with this in the long run. Have my parents on this as well. Whether or not it induces longevity or whether it just gives quality of life, the B3's are very needed, and this is one of them. Niacin, Niacidamide and Niagen all use different pathways with the sirt activity. You can take all 3. However tend to get headaches on niacin. They all create the sirts or increase them.

Best product .Helping to keep you happy

Didnt see nor feel any difference

I normally get 4 to 5 hours of sleep and I get exhausted after a days work. While at work, I always feel sleepy and yawning all the time in mid afternoon. When I get home I feel so tired that I will sleep for an hour to get a little rest. Since taking this, I felt that I have enough energy for the whole day. I still yawn in the afternoon but I feel that I have more energy to get me through the day. My wife notice it and told me that I don't complain of exhaustion and I don't take a short nap anymore. I do recommend this to everyone.

I give this product 5 star
