Why Sirtuins and PARPs Fail Without NAD+
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every living cell and essential for over 500 enzymatic reactions. It is most critical for mitochondrial energy production (ATP synthesis) and as a substrate for sirtuins — the longevity proteins that control epigenetic aging.
▸The Decline Problem
NAD+ levels decline approximately 50% between age 20 and 50. This decline is directly associated with: reduced energy production, impaired DNA damage repair, epigenetic dysfunction, metabolic slowdown, and reduced stress resistance. Virtually every hallmark of aging is connected to NAD+ decline.
▸How NAD+ Works
NAD+ is required by:
→**PARP enzymes**: DNA damage repair — critical for genomic stability
→**Sirtuins (SIRT1-7)**: Epigenetic regulators that control aging, inflammation, and metabolism
→**Complex I of the electron transport chain**: Core of mitochondrial energy production
Restoring NAD+ activates all of these pathways simultaneously — a true systems-level anti-aging intervention.
▸Results
Users report significant increases in physical energy within 1-2 weeks. Exercise performance improves. Cognitive clarity and motivation improve (NAD+ drives dopamine synthesis pathways). Long-term benefits include improved metabolic markers and reduced inflammation.
Where NAD+ Replenishment Shows Up First
- Restores NAD+ levels that decline 50% by age 50
- Activates sirtuins (SIRT1-7) — the master longevity proteins
- Powers PARP enzymes for DNA damage repair

- Synergizes with caloric restriction and exercise for longevity
NAD+: The Master Longevity Molecule That Powers Every Cell in Your Body
50% Decline by 50
NAD+ levels drop approximately 50% between ages 20 and 50 — this decline drives most of the biochemical hallmarks of aging.
Sirtuin Activation
Sirtuins (SIRT1-7) are the master longevity proteins. NAD+ is their only substrate — no NAD+, no sirtuin activity.
DNA Repair Engine
PARP enzymes that repair DNA damage — the #1 cause of cancer and cellular aging — require NAD+ to function.
Energy Restoration
Powers Complex I of the mitochondrial electron transport chain — restoring the foundational energy production that declines with aging.

NAD+ Administration, Demystified
What does NAD+ do and why does it decline with age?+
NAD+ is a coenzyme essential for energy metabolism, DNA repair, and sirtuin (longevity protein) activation. NAD+ levels decline roughly 50% between ages 40 and 60. This decline is now considered a primary driver of aging — impairing mitochondrial function, reducing DNA repair, and decreasing cellular energy production.
Is NAD+ injection better than oral NMN or NR supplements?+
Injectable NAD+ achieves significantly higher plasma levels than oral NMN or NR supplements, bypassing the conversion steps and gut absorption limitations. Oral NMN and NR are precursors that must be converted to NAD+ — a process that becomes less efficient with age. For maximum NAD+ restoration, injection is superior, though oral precursors provide meaningful benefit at lower cost.
What is the NAD+ injection protocol?+
Typical subcutaneous protocol: 100–500mg injected 3–5× per week. Start at 50–100mg and titrate up. Some protocols run 10-day intensive cycles 2–4× per year at higher doses. Subcutaneous injection is more practical than IV for self-administration.
