Which is better, Gene Harbor NMN9000, Le Jiaxin or Bai Ruijian NMN Beauty Capsule?

The component side said that it would definitely choose the gene port. The purity of NMN in his products is very high, and it has also obtained authoritative certification from many countries. This is what Le Jiaxin can't compare? Moreover, there is really nothing to comment on this one of Bairuijian, and all three models are the first to promote gene harbor. I suggest you choose this big brand for health care products, and you can rest assured that you can eat it yourself.
