Chronic inflammation accelerates the aging process, and targeted clearance of senescent cells shows potential in alleviating age-related decline. PCC1, a potent senescent cell clearance agent in grape seed extract (GSE), has limited applications due to its low oral bioavailability. This study introduced a novel GSE formulation, Natural Senolytics PCC1 (NSPCC1), which significantly enhanced PCC1 absorption and metabolic characteristics. Validation in two mouse aging models demonstrated that oral administration of NSPCC1 markedly extended lifespan and promoted healthy aging. The formulation improved the capacity for hematopoietic stem/progenitor cell differentiation and reduced age-related myeloid cell bias. Comprehensive histological analysis revealed attenuated aging phenotypes in bone marrow and skin, improved peripheral blood erythroid parameters, and a partial increase in blood antioxidant capacity, alongside reduced M1 macrophage infiltration and fibrosis in liver, kidney, and lung tissues. These effects were validated through histological assessments, including H&E, Masson, F4/80, and iNOS staining. This study highlighted the pivotal role of hematopoietic stem cells in aging and established NSPCC1 as a promising natural intervention for age-related pathologies. Its enhanced efficacy lays the groundwork for deeper exploration of natural products in aging biology and provides crucial support for the development of safe and effective anti-aging therapies.
