I think that is only in the USA. UK Amazon still has NMN (If there actually is NMN in what appears)
May not come to effect. Manufacturers may do what NAC producers did.
This isn’t the first time Amazon has taken action to remove from its platform a popular dietary supplement that FDA determined was barred in natural products due to being either approved or investigated as a drug before it was marketed in a supplement. Amazon did so with NAC (N-acetyl-L-cysteine), which was later the subject of a lawsuit filed by the Natural Products Association against FDA in U.S. District Court in Maryland.
Ultimately, FDA adopted a policy of “enforcement discretion” to permit the sale of NAC supplements, and Amazon last year resumed sales of the products.
