was ist nmn supplement — what can you do yourself?

NMN (Nicotinamide Mononucleotide) is a precursor to NAD+, a key coenzyme in energy metabolism and DNA repair. Animal studies show promising anti-aging effects, but human evidence remains limited and mixed. The evidence grade is 'mixed' – some small human trials exist, but no long-term data or clear dosing guidelines. What you can do yourself: A healthy diet rich in vegetables, regular exercise, adequate sleep, and stress management naturally support NAD+ production. NMN supplements are unregulated; quality and purity vary widely. Without medical supervision and proven benefit, self-supplementation is not recommended. DNA tests like those from MyBody-X cannot predict your need for or response to NMN.
