Precursors
NAD, NMN, NR, NMNH, and NADH are essential molecules in energy production, cellular repair, and overall metabolic health.
Even though precursors to NAD can be found in fish, poultry, dairy products, and some fruit and veggies, the amounts aren’t enough to significantly impact NAD levels in the body.
This is why supplements with NAD, NMN, NR, NMNH, and NADH can be advantageous — helping to supply the body with a steady source to maintain the health of cells.
