NAD+

NAD+ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme involved in cellular energy production and metabolism regulation. Without it, mitochondria — the energy powerhouses of cells — cannot function optimally. NAD+ supports cellular regeneration, energy exchange, and DNA maintenance. Its levels naturally decline with age, making it a key focus in modern longevity strategies. NAD+ is often regarded as the molecule of youth and energy, due to its fundamental role in cellular life.
