NAD is best consumed in a specific way.

Current research suggests that the best way to increase NAD+ levels is through natural methods like supporting the body's own production pathways using precursors such as NR (Nicotinamide Riboside) and NMN (Nicotinamide Mononucleotide), rather than direct supplementation. Approaches like intermittent fasting can also stimulate NAD+ production. There is evidence to suggest that simply consuming NAD+ directly is not as effective due to its instability and the body's limited ability to absorb it in this form.
