Enzan health management

Never eaten this brand. There are too many NMN brands now, and I don't know which one is good. I chose YishengNo. 18000, which was well evaluated in JD.COM with high purity and favorable price. If you consider the cost performance, it is right to choose this one, and the reputation is good. I usually eat it half an hour after breakfast. NMN can improve mitochondria, increase mitochondrial productivity and promote body metabolism. I may be too excited to sleep at night, so it is more appropriate to eat after brunch.
