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. NAD+ Platinum is an all-in-one longevity formula supporting three key pillars of longevity: cellular NAD+ replenishment, longevity gene (sirtuins) activation, and methylation support.
