I did a lot of research before I purchased NMN from vivanmn. For me, the most important things were: a/made in the UK b/Verified by third-party c/500 mg capsules. I take 1g a day and vivanmn Offers the best price for the quantity I require. I have only been taking it for about a couple of months, but will definitely be purchasing from these guys again ,highly recommended.
