Protocol Glossary
Science-backed definitions for every term in your health data: plain English and the mechanism behind it.
ApoB (Apolipoprotein B)
The best single number for cardiovascular risk
→ Read definitionChronic Low-Grade Inflammation
A persistent, low level immune activation that lingers for months or years instead of resolving like a normal injury or infection response.
→ Read definitionEpigenetic Age
A DNA methylation based estimate of how fast your body is aging, separate from your birth date
→ Read definitionHDL Cholesterol (HDL-C)
The "good cholesterol" that is more nuanced than its label suggests
→ Read definitionHomocysteine
An amino acid byproduct that signals B-vitamin status and vascular risk
→ Read definitionInflammatory Cytokines
The signaling proteins immune cells release to trigger and coordinate the body's inflammatory response.
→ Read definitionLDL Cholesterol (LDL-C)
The most tracked lipid marker, and the most misread
→ Read definitionLDL Particle Size (LDL-P vs. LDL-C)
Why two people with the same LDL number can have very different risk
→ Read definitionLipoprotein(a) [Lp(a)]
The inherited cardiovascular risk factor most panels skip
→ Read definitionmTOR Pathway
The cellular switch that decides whether your body builds new tissue or breaks old tissue down for recycling.
→ Read definitionNAD+
A coenzyme every cell needs to convert food into energy and repair DNA, and one that reliably declines with age.
→ Read definitionNatural Killer Cells
The immune system's rapid-response cells that hunt down infected and cancerous cells without needing to see them before.
→ Read definitionNon-HDL Cholesterol
A better total atherogenic burden marker than LDL-C alone
→ Read definitionSenescent Cells
Aged or damaged cells that permanently stop dividing but refuse to die, quietly driving inflammation as they accumulate with age.
→ Read definitionTelomere Length
The length of the protective DNA caps on your chromosomes, a marker of cellular aging that shortens with cell division and stress.
→ Read definitionTriglyceride-to-HDL Ratio
A proxy for insulin resistance hiding inside a standard lipid panel
→ Read definitionVitamin D
The hormone your body makes from sunlight
