Procyanidin C1 (PCC1)

Decoding cellular longevity through Procyanidin C1, a natural compound showing remarkable potential in addressing cellular aging and extending healthspan through its unique senolytic and senomorphic properties.

What is Procyanidin C1?

Procyanidin C1 is a natural compound found in grape seeds that selectively eliminates senescent "zombie" cells[6], extending lifespan by 64.2% in aged mice through its unique dual action as both a senolytic (killing senescent cells) and senomorphic (reducing their harmful secretions)[5].

Nature's Solution to Cellular Aging

Procyanidin C1 selectively eliminates senescent cells while preserving healthy ones. Found naturally in grape seeds and other plants, it represents a breakthrough in addressing aging at the cellular level.

The Senescence Problem

Senescent cells accumulate with age, secreting inflammatory factors that accelerate aging and disease[6]. Traditional approaches fail to address this root cause, focusing on symptoms rather than cellular dysfunction.

By 2050, 16% of the world's population will be over 65, with age-related diseases costing healthcare systems trillions annually.

Evidence-Based Results

Peer-reviewed research shows PCC1 extends lifespan by 64.2% in aged mice[5], improves physical function, and reduces markers of aging[7]. This natural compound offers hope for healthier, longer lives.

PCC1 treatment equivalent to adding 20+ healthy years to human lifespan based on mouse model translations.

Key Benefits & Mechanisms

Senolytic Activity

Selectively eliminates senescent 'zombie' cells while sparing healthy cells, reducing harmful inflammatory compounds.

87% reduction in senescent cells

Senomorphic Effects

Modifies senescent cell behavior to reduce harmful inflammatory signals (SASP), decreasing negative impact on tissues.

92% reduction in SASP factors

Lifespan Extension

Research shows PCC1 extended median post-treatment lifespan by 64.2% in aged mice, equivalent to humans 75-90 years old.

64.2% lifespan extension

Multi-System Benefits

Demonstrates benefits across cardiovascular, neurological, renal, and immune systems through comprehensive cellular rejuvenation.

5+ organ systems improved

Molecular Mechanism

Procyanidin C1 is a trimeric proanthocyanidin with a unique molecular structure that enables selective targeting of senescent cells while preserving healthy tissue.

  • Induces apoptosis specifically in senescent cells[6]
  • Reduces SASP (Senescence-Associated Secretory Phenotype)[5]
  • Modulates key longevity pathways including SIRT3/FOXO3[8]
  • Enhances mitochondrial function and dynamics[5]
