NAD (Nicotinamide Adenine Dinucleotide) and NMN (Nicotinamide Mononucleotide) are two critical compounds in the realm of cellular metabolism and energy production. Both play significant roles in the body’s ability to maintain optimal health, particularly as we age. As our understanding of these molecules deepens, their potential benefits and distinctions have captured the attention of researchers and health enthusiasts alike. At the cellular level, NAD is a coenzyme found in all living cells, crucial for various biochemical reactions, especially those involved in converting food into energy. It acts as a shuttle, transferring electrons in redox reactions, which are integral to energy production in the mitochondria. However, NAD levels decline with age,…
