Great product no stomach upset and feel great on this

This is my main supplement for energy and mental clarity. I take this every day and I can feel a dramatic difference when I don’t take it. I have used many other NAD supplements and this is by far my favorite. Just solid energy and mental clarity. I trust this brand to other supplements as well.

Good price for NAD. This is one of those supplements where you have to trust the science; you're not likely to feel any effect by taking NAD. Endogenous production of NAD decreases as we age, and therefore causes us to age. David Sinclair is one of the most cutting edge aging researchers in the world and he talks a great deal about NAD's importance in aging. You can listen to podcasts he has with various big podcasters to learn more. I used one bottle so far and did not experience any side effects - so I bought another. I feel pretty solid too. This NAD from "High Performance Nutrition Co." may be the best value on the market, and one that I trust. If you're finding NAD that is inexpensive then my guess is that it is of poor quality or completely fake, atleast at this time in the year 2020.

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.

Le daré 5 estrellas, porque el envío fue muy,muy rápido,noce que tan buena sea este producto,llevara tiempo para ver el resultado, recomiendo al vendedor.

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 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 started this earlier in the week and the next day i had nausea and a terrible feeling. At first I didn’t associate it with this product. Then the next day i took it and felt dizzy and nausea again it would come and then go and come back. 4 days later I said to myself I have to see my doctor my son who is a medic took my blood pressure and checked my heart rate and said your vitals are normal but make an appointment with the doctor. I thought what have I eaten or introduced lately and realized the only thing was this product. Today I didn’t take it and i have no nausea or dizziness so I won’t take it anymore. Really hoped it was for me 🥺
