Wie sieht die aktuelle wissenschaftliche Basis zu NMN aus?Aktualisiert 8 months ago

Tausende von Menschen haben NMN in angemessenen Dosierungen (in der Regel 125 mg bis 1 g) im Laufe der Jahre ohne Probleme eingenommen, und seine Sicherheit sowie die Effektivität wurde durch mehr als wissenschaftliche Studien bestätigt.

• The efficacy and safety of β-nicotinamide mononucleotide (NMN) supplementation in healthy middle-aged adults: a randomized, multicenter, double-blind, placebo-controlled, parallel-group, dose-dependent clinical trial (2023): Walking distance increase during the six-minute walking test was statistically significantly higher in the 300 mg, 600 mg, and 900 mg groups compared to placebo at both days 30 and 60 (all p < 0.01), with longest walking distances measured in the 600 mg and 900 mg groups. The blood biological age increased significantly in the placebo group and stayed unchanged in all NMN-treated groups at day 60, which resulted in a significant difference between the treated groups and placebo (all p < 0.05) https://pubmed.ncbi.nlm.nih.gov/36482258/

• Pulse wave velocity values indicating arterial stiffness tended to decrease in the NMN intake group. However, no significant difference was found between the two groups. Long-term NMN supplementation at 250 mg/day was well tolerated and did not cause adverse events. NMN safely and effectively elevated NAD+ metabolism in healthy middle-aged adults. https://pubmed.ncbi.nlm.nih.gov/36797393/
