The 12 Hallmarks of Aging

Interactive guide to the biological drivers of decline. Click cards to expand details.

1. Primary Hallmarks (The Root Causes)
🧬 Genomic Instability ā–¼
DNA damage accumulates from toxins and internal stress, corrupting the cellular blueprint.

Marker: 8-OHdG levels
Study: View Research on PubMed

ā³ Telomere Attrition ā–¼
Protective chromosome caps shorten, leading to cellular exhaustion and permanent arrest.

Study: Full 2023 Review

āš™ļø Epigenetic Alterations ā–¼
Changes in gene expression switches cause cells to lose their original functional identity.

Study: Read Cell Study

ā™»ļø Disabled Autophagy ā–¼
Cells lose the ability to recycle damaged parts, leading to toxic “cellular trash” buildup.
2. Antagonistic Hallmarks (The Responses)
šŸ”‹ Mitochondrial Dysfunction ā–¼
Energy powerhouses become leaky, producing less fuel and more oxidative stress.
🧟 Cellular Senescence ā–¼
Damaged cells refuse to die and inflame healthy neighbors with toxic signals.
3. Integrative Hallmarks (The Outcomes)
šŸ”„ Inflammaging ā–¼
Chronic systemic inflammation that acts as a catalyst for all other aging hallmarks.
🦠 Gut Dysbiosis ā–¼
Imbalances in gut bacteria that lead to “leaky gut” and systemic toxin leakage.
