Life Extension NAD+ 100mg is a supplement formulated to support cellular energy, metabolism, and healthy aging. NAD+ (Nicotinamide Adenine Dinucleotide) plays a vital role in key biological processes like DNA repair and mitochondrial function. With age, NAD+ levels naturally decline, but supplementing with Life Extension's NAD+ can help restore these levels, supporting brain health, energy production, and longevity. Each vegetarian capsule provides 100mg of NAD+, making it a great option for individuals seeking to enhance cellular vitality and overall well-being.
