Started NMN on a friend's recommendation. Can't say it's been life-changing, but I do feel slightly more alert and less tired by the end of the day. The effects are not huge, but for someone in their late 40s like me, every little bit helps.

I was half-expecting NMN to be just another overhyped supplement, but I'm genuinely pleased with the results! It's been about two months, and I've noticed a real increase in my daily energy levels and mental clarity. The changes are subtle but definitely there. For someone who's generally sceptical about supplements, I'm quite impressed and looking forward to seeing more benefits.

Two months in, and the change in my energy levels is subtle but real. It’s not a cure-all, but as an addition. I like it for the science, I do feel a bit more 'alive' each day. At my age, every bit of vitality counts. I am 56 and my kids want me to take other stuff too

After retiring, my kids buy me this. My friends also talk about aging a lot. I've been taking it for a few months now, and I've noticed increase in my energy and brain. It's a valuable to me daily routine. My kids feel good i take it.

Been using NMN for a couple of months now. I can say I've noticed changes, but there's a subtle difference in how I feel daily, this is a good sign and you're supposed to take NMN for at least 6 months. Less foggy in the brain, maybe? It's pricey, but there is no limit how much I will spend on my health

My decision to purchase NMN was largely influenced by Masi's branding, which struck me as particularly science-driven and transparent compared to other brands. After several months of consistent use, noticeable energy levels and cognitive function. It feels kind of like coffee but without the crazy energy.

Took NMN for a month now. Surprisingly, I feel a tad more vibrant each day. Didn't expect much, but it's pleasingly noticeable

Read about NMN decided to test it. Mild improvements in alertness and wellbeing. Have tried some of the other stuff, I currently have 3 different NMN and Resveratrol brands. Masi feels the most quality by the package and the supplement and has good information. I will purchase from the my favorite one when I run out

After reading a fair bit about NMN and its potential anti-aging benefits, I decided to give it a go. While the scientific community still seems divided, I personally have observed some improvement in my overall wellbeing. It's no magic pill, but the science behind it is intriguing enough to keep me going.
