NIAGEN+ Precursor is an advanced NAD+ support therapy formulated with pharmaceutical-grade nicotinamide riboside chloride (NR), a highly efficient precursor that helps naturally increase the body's NAD+ levels. NAD+ is an essential coenzyme involved in cellular energy production, DNA repair, healthy mitochondrial function, and overall metabolic health. As NAD+ levels naturally decline with age and are further reduced by stress, poor diet, lack of exercise, alcohol consumption, and other metabolic stressors, NIAGEN+ helps replenish these levels to support vitality, healthy aging, cognitive performance, and physical wellness. Manufactured under strict pharmaceutical quality standards, NIAGEN+ is designed to provide a high-quality, well-tolerated solution for individuals looking to optimize cellular function and promote long-term health from the inside out.
