I just finished my first bottle of NMN. I wanted to try it after hearing a lot of good reviews about it, but wasn’t sure which brand to use. Online brands are quite expensive and I didn’t want to put money into a supplement which I cannot afford for at least 6 months to see a viable result. For youth is easy on my pocket and I would like to continue it to see further improvement.I take one capsule with my morning protein drink. I don’t feel sluggish and the general afternoon slump is quite low compared to previous occasions
