The Most Direct Precursor to our "Anti-Aging" Molecule - NAD+ is our genetic key to longevity, but levels naturally decline as we age. NMN is the most direct NAD+ precursor (unlike NR, commonly used in NAD+ supplements). NAD+ and Sirtuin Boosting Cofactors for Optimal Results - Support cognitive, immune and metabolic functions with this uniquely powerful blend. Resveratrol and quercetin help supercharge longevity proteins to support genome integrity and optimal cellular functioning. TMG and B vitamins help support balanced methylation and keep the NAD+ cycle turning. Unsurpassed Bioavailability - Quicksilver Scientific's exclusive liposomal delivery technology mimics the body's own NMN transport system and offers rapid uptake into the bloodstream and cells.
