NAD+ (Nicotinamide Adenine Dinucleotide) is a naturally occurring coenzyme found in all living cells. In recent years, NAD+ has gained significant attention in scientific research for its potential to enhance mitochondrial health, improve cognitive performance, and slow cellular aging. NAD+ 500 is provided in high-purity lyophilized form for research focused on energy metabolism, neurodegeneration, and sirtuin activation.
