30 Days on NMN - Too Early to Judge, But Hopeful!
I have been taking Real NAD easy melts distributed by Avior Nutritionals for several years. I am a real fan of NAD and have had many good changes to report from using NAD in various forms. A physician in the north-east has campaigned in favor of NMN, a precursor to NAD. So when I saw it listed at Swanson I thought I would give it a try. It's been only 30 days and I have not noticed any additional impacts. NAD levels in the bloodstream are very difficult to measure, so I have no statistical evidence of effectiveness. I will continue for a few months and see how or if I notice any improvement in energy levels or general health.

no noticeable difference
have not noticed any change in energy levels or metabolism using this. And it's pretty expensive.

Promising benefits
[This review was collected as part of a promotion.] I started taking this energy and metabolism support supplement about two weeks ago. During this time, I’ve noticed a slight increase in my overall energy levels, particularly when taking it first thing in the morning on an empty stomach. While I haven’t experienced a significant change in overall wellness yet, I do feel there may be a modest boost to my metabolism. So far, the results have been subtle but encouraging. I plan to continue taking NMN for a full 30 days to better evaluate its long-term effects. It’s possible my body simply needs more time to adjust. Depending on how I feel after completing the first bottle, I may consider purchasing another to see if the benefits become more noticeable with extended use.

Postpartum kick I needed
[This review was collected as part of a promotion.] I was skeptical about taking this supplement, but since starting I have more energy and don’t feel like I need a nap in the middle of the day. I’ve also noticed I have better digestion and consistent bowl movements (tmi).

Not sure I felt much of a difference... yet.
[This review was collected as part of a promotion.] I have been taking this supplement for about 4 weeks. Some days, I felt like maybe I felt a little boost and others I felt just as tired as before, so it's really had to discern if it was having an impact. However, so many great reviews seemed to be taking it for a long period of time, so I think it could likely be that it is one of those things that takes more than a couple weeks to really start noticing significant progress. Regardless, I will keep taking it to see if there is a notable difference.

So far so good!
[This review was collected as part of a promotion.] So far, I’m satisfied with this supplement. I noticed a change in my energy after about 10 days. It was subtle, but I just remember thinking I had been more alert and less tired feeling recently. I’m very excited to keep taking it. I feel like the best results are probably after you’ve been taking it for a while to notice more metabolic effects. I didnt have any negative side effects and they go down easy. I’d recommend for anyone looking to supplement with this supplement that isn’t talked about enough!

NCM Review
[This review was collected as part of a promotion.] How have you felt since taking this supplement over time? Following the consumption of the NCM supplement I have noticed a subtle increase in energy. Like I am a more awake. Have you noticed a lift in your daily energy levels? Yes, my energy has increased to give me an additional hour of time in my day. How has this supplement impacted your metabolism or overall sense of vitality? I have noticed noticed a change in my metabolism yet, this may require more time for changes to be measured. What differences have you noticed in your wellness routine since adding this supplement? I feel I can walk longer during my cardio circuit. It’s an amazing feeling to have an extra step for my health. What did you like most about this supplement? I enjoyed that the pill did not have an after taste and was easy to swallow. The bottle did not have an odor to it either. There were no multiple doses to take daily.

Pleasantly surprised
[This review was collected as part of a promotion.] I’ve been trying out NMN for a bit now, and honestly, surprised me. The main thing I noticed was feeling a little sharper and more focused throughout the day. A lot of things that claim “focus” either hit too hard, make me jittery, or crash me later. NMN didn’t do any of that. It was more like my baseline got turned up slightly. For me, the effect was pretty quick, within the first week. I’m not treating this like a miracle pill, but compared to a lot of “brain supplements out there, this actually feels cleaner. No side effects I could tell, and it stacked fine with my normal vitamins and coffee.Overall, not a life changing supplement, but definitely something I’ll keep taking to see if the longer-term stuff (energy, skin, recovery after power yoga) shows up.

Effective Supplement!
[This review was collected as part of a promotion.] I started this supplement to increase energy levels and improve moods. I did notice an increase in my motivation to get things done around 2 weeks after starting. Overall, a solid supplement.

Energy Is Way Up - thanks to NMN and other lifestyle changes
[This review was collected as part of a promotion.] I’ve been taking NMN daily for about a month now, and while I’ve made other changes at the same time (like prioritizing sleep and using a prescribed sleep aid), I do feel like it’s helping. My sleep scores, which used to be in the 50s or 60s, are now regularly in the 80s and even 90s, and my readiness scores have improved as well. That’s translated into having more consistent energy during the day, which has been a big win. What I like most is that it’s such an easy supplement to add into my routine, and it feels like it’s supporting the other steps I’m taking for better health and energy. All in all, I'll continue taking it as energy is UP across the board, likely for a number of reasons.

Didn’t feel much
[This review was collected as part of a promotion.] I’ve been taking this supplement for the last few week, and honestly have not noticed a change in my wellness or energy levels. No negative side effects, but nothing noticeable on the other side either. Is it something I would continue to use, sure. But I wouldn’t go out of my way to take it because I noticed nothing new or better in the way I feel.

Nothing too special
[This review was collected as part of a promotion.] I don't normally notice much difference from any supplements, even after taking this for a month I still didn't seem to notice any big differences. I haven't gained weight, but I'm not sure if that's due to this. Same thing when it comes energy, it's been better, but I cannot definitively say it's from this. The most definitive thing I can say is that it helped me to get into a habit of taking my meds. While I didn't personally notice any differences, I think this could be something that would work for others. I liked that it helped me establish a routine so I can start taking other meds. Overall I'd say this want anything too big of a difference maker for me, but I wouldn't put it past that for someone else however.

unremarkable
[This review was collected as part of a promotion.] Being very honest here, this was an unremarkable product for me personally. I'm sure that it may move the needle for certain people, but I did not notice any difference and would not repurchase. To be fair, this is nothing against this particular brand as I would likely feel like same way about this product regardless of brand. Do your research, and consider this brand if the NMN supplement seems like a good fit for your personal needs.

This is good stuff! This is the cornerstone of my supplementation routine.
Look up David Sinclair, Harvard researcher who studies aging and epigenetics. He says take this in the morning with resveratrol. He personally takes 1 whole gram of each. They work together. The NMN is the gas resveratrol is the gas pedal.

Great energy boost & mitochondrial boost!
I really love this NMN for energy... I definitely notice a difference and I love to take it with PQQ. The perfect pick-me-up that is good for me too!!!

(no review title)
The dosage is higher than any other I’ve come across. So price is good. Recommended dose by experts is 1gm. So 3ish pills versus the 10 I have to take from “less expensive” brands is not worth it. Pay attention to dosing and number of pills to get that. Swanson is best bang for your buck if care about dosing

Improved my speech fluidity!
I rarely give reviews, but maybe I can help someone else with this review. I’ve taken 1 bottle and I can already see a difference in my cognitive abilities and speech fluidity. I’m 67 y/o & I’ve struggled with halting, choppy speech for years, which is embarrassing. It gets worse when I’m under stress. I’ve researched for years, trying to find a solution. I heard about NMN’s anti-aging benefits on YouTube, and was happy to find Swanson sells it, & it’s affordable. The speech improvement was a happy side effect! I’m hoping to see even more benefits after my second bottle.
