Key Clinical Longevity Interventions

•Lowering RDW & Anisocytosis: Optimize vitamin B12, folate, and iron status; reduce systemic oxidative stress to preserve bone marrow erythropoiesis.

•Suppressing Inflammaging (hs-CRP): High-intensity resistance training + Zone 2 cardio, Mediterranean diet, and high-dose EPA/DHA omega-3 fatty acids.

About Morgan Levine PhenoAge

Developed by Dr. Morgan Levine at Yale University and published in Aging, PhenoAge is an epigenetic proxy trained on 10,000+ individuals from the CDC NHANES III cohort.

Unlike expensive DNA methylation arrays, PhenoAge calculates accurate biological age using accessible, standard clinical chemistry and complete blood count (CBC) tests.
