Stem cells
Stem cell decline limits regeneration: senescent stem cells renew poorly, microbiome shifts impaired intestinal stem cells in old mice, and adult neurogenesis drops sharply in Alzheimer's.
4 interventions act here
Proline
Collagen-rich amino acid that restored mitochondrial function in senescent stem cells in a 2024 study.
In my stack
Alpha-Ketoglutarate (AKG)
Krebs-cycle metabolite that drops sharply with age; supplementation extended lifespan and healthspan in mice.
In my stack
GHK-Cu (copper peptide)
Copper-binding tripeptide that declines with age and supports skin, wound healing, hair and lung repair.

Microplastics Reduction
Cutting nanoplastic exposure, found in arterial plaque and brain tissue, and keeping the gut barrier strong.
