Cellular Healthspan & Geroprotection

Longevity Nutrition

Biological aging is not a fixed, unidirectional clock. Discover how nutrient-sensing pathways (mTOR, AMPK, Sirtuins) and bioactive phytochemicals can clear senescent cells, fuel mitochondrial biogenesis, and extend your healthspan.

The 4 Cellular Longevity Pathways

Molecular Targets
Nutrient Sensing

mTOR Downregulation & Protein Pulsing

The Mechanistic Target of Rapamycin (mTOR) governs cellular growth. Chronic elevation accelerates senescence and halts internal recycling. Pulsing amino acid intake allows periods of deep cellular maintenance.

Clinical Target: Fasting Insulin < 5 µIU/mL
Energy Sensor

AMPK Activation & Metabolic Flexibility

AMP-activated protein kinase acts as the cell's master fuel gauge. Triggered by caloric depletion, fasting, and polyphenols, AMPK turns on fatty acid oxidation and drives mitochondrial biogenesis.

Clinical Target: Triglyceride / HDL Ratio < 1.0
DNA Epigenetics

Sirtuin (SIRT1-7) & NAD+ Optimization

Sirtuins are NAD+-dependent deacetylase enzymes that coordinate chromatin silencing, double-strand DNA break repair, and circadian rhythm alignment. Sirtuin efficiency relies directly on high NAD+/NADH ratios.

Clinical Target: Cellular Intracellular NAD+ Levels
Cellular Cleanup

Senolytic Clearance & Autophagy

Over time, damaged cells enter irreversible cell-cycle arrest (senescence), secreting a pro-inflammatory cocktail (SASP) that damages neighboring tissue. Senolytic nutrients selectively induce apoptosis in these 'zombie' cells.

Clinical Target: hs-CRP < 0.5 mg/L
