The packaging is very firm. When I got it, there was no problem with the internal and external packaging, which made me feel at ease to eat it. I thought it would take a long time to have an effect, but I didn't expect that I soon felt its role, slept better, my skin condition was better, and my brain turned faster.

I have always been skeptical of the product claims, but I have taken this product for more than half a year and am very satisfied with the results. People often guess that my age is around 60; actually I will be 70 next month. According to my telephone pedometer, I can walk 2 kilometers a day now, which I could never do before. Most days, I feel great.

I'm all into anti-aging at all costs. I love this supplement and the benefits that accompany it. Great product! Nice addition to anyone trying to improve their well being.

I can see and feel the nmn supplement working already and it's only been two weeks since I started taking them. I will definitely be reordering this amazing nmn again later.

I am 40s. I have been looking for supplements to help me fight against aging. Seeing this NMN has made me determined to try. I have also started my five-year plan. I want to make my body healthy and young again. I have taken it for 2 months now. My energy level has improved initially, and my memory has also improved greatly, including sleep, Now I don't often wake up in the middle of the night
