At youngle, quality comes first. A US study recently examined the quality of products from 22 different suppliers and came to the sobering conclusion that more than half offered either no real NMN or only low-quality NMN.

For us, transparency is not an empty promise, but a basic requirement, especially when it comes to the quality of our products. We subject each of our products, including NMN, to both internal and external quality controls. Our manufacturer and the independent Arotop laboratories at Limbach Analytics in Mainz, Germany, test and certify each product for purity and heavy metal content. You can view NMN’s analysis certificates here. We invite you to convince yourself of the quality of our products
