A NAD⁺ supplement is a wellness product designed to support the body’s natural levels of nicotinamide adenine dinucleotide (NAD⁺), a vital coenzyme involved in cellular energy production, metabolism, and DNA repair. Often formulated with NAD⁺ precursors such as NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside), these supplements help promote sustained energy, mental clarity, and healthy aging. By supporting cellular function and reducing oxidative stress, NAD⁺ supplements are commonly used to enhance overall vitality, improve focus, and maintain metabolic health as part of a balanced lifestyle.
