SCIENCE
How It Works.
NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme present in all living cells, central to cellular redox reactions that power mitochondrial oxidative phosphorylation. Without sufficient NAD+, cells cannot oxidize glucose, fatty acids, or amino acids to synthesize ATP.
Beyond energy metabolism, NAD+ is consumed as a co-substrate by sirtuins (longevity-regulating deacetylases) and PARP enzymes responsible for repairing DNA double-strand breaks. Because cellular NAD+ levels decline by up to 50% between youth and middle age, replenishment protocols are central to longevity biology.
WHAT TO EXPECT
Cellular redox ratio shifts and subjective vitality improvements are typically evaluated within 1–2 weeks, with sustained epigenetic and metabolic benefits assessed across 8–12 week models.

FAQ
Protocol Questions
How does injectable NAD+ reach target cells?+
Injectable delivery bypasses gastrointestinal degradation. In the bloodstream, extracellular NAD+ is cleaved into nicotinamide/NR and taken up by cells to be rapidly resynthesized via the intracellular salvage pathway.
What is the difference between subcutaneous and intramuscular NAD+ protocols?+
Subcutaneous delivery provides gradual capillary uptake with milder vascular flush sensations, whereas intramuscular injection achieves rapid systemic bioavailability.
