NAD+, or nicotinamide adenine dinucleotide, is a ‘long-life’ molecule present in every cell of the body and is essential for life. As we age, NAD+ levels naturally decline causing numerous cellular processes to go haywire. This, unfortunately, is part of the aging process. However, replenishing our cellular NAD+ levels with supplementation can help. Studies show NAD+ repletion boosts energy production, upregulates cellular repair, and increases the body’s resilience to age-related conditions, supporting a longer and enhanced healthspan.
