NMN - Uthever® is proudly made in the Netherlands, adhering to the highest standards of quality and safety. Our manufacturing process follows strict guidelines to ensure the purity and potency of each ingredient. The production of NMN involves a complex process, including phosphorylation of nicotinamide riboside, and steps like clarification, concentration, and grinding of the substrate, ensuring a purity level of 99%.
The remaining 1% consists of nicotinamide riboside (NR) and nicotinamide (Nam). NR is the starting material, and Nam is the degradation product, both of which are harmless.
