Maintaining serum 25(OH)D concentrations above 30 ng/mL (50 nmol/L) reduces oxidative stress, inflammation, and mitochondrial dysfunction, thereby slowing aging and reducing all-cause mortality.

Aim for a serum 25(OH)D level of at least 30 ng/mL. This can often be achieved through sensible sun exposure or supplementation (e.g., 1000-4000 IU/day for most adults). This supports mitochondrial health and reduces oxidative stress, which are key drivers of aging.

ModerateSupportsMEDIUM confidence
Vitamin D adequacy leads to less oxidative stress and improves mitochondrial and endocrine functions, reducing the risks of disorders, such as autoimmunity, infections, metabolic derangements, and impairment of DNA repair; all of this aids a healthy, graceful aging process.
