"Normal" is not optimal.
A plain-English guide to the biomarkers that matter: what each one measures, what it signals, and what optimal looks like for men and women.
'In range' is not the same as optimal.
Standard lab reference ranges are built from the general population, which today includes a lot of tired, inflamed, metabolically-off people. Falling inside those ranges only means you're not obviously sick, not that you're thriving.
Optimization medicine looks at the same markers through a tighter lens: what does the data look like in people who feel great, recover well, sleep deeply, and age slowly? That's what we mean by optimal.
The ranges below are educational reference points used in longevity and functional medicine, not diagnostic cutoffs. Your provider owns interpretation.
Metabolic + Blood Sugar
How efficiently your body handles fuel. Early cracks show up here years before disease.

Lipids + Cardiovascular
Cholesterol is only the beginning, particle count and inflammation matter more.

Inflammation
Silent, chronic inflammation is upstream of nearly every modern disease.

Thyroid
Your metabolic thermostat. Standard 'in range' often misses real dysfunction.
