Biomarkers
Longevity biomarkers
Understand your lab results — explained simply. Each biomarker includes what it measures, why it matters, and what you can do about it.
Cardiovascular
Total Cholesterol
A starting-point measure of all the cholesterol in your blood. It's useful as a baseline, but the breakdown matters more.
LDL Cholesterol
Often called 'bad' cholesterol. High LDL is one of the main drivers of heart disease — but the type and size of particles matter too.
HDL Cholesterol
The 'good' cholesterol that helps remove harmful cholesterol from your blood. Higher is generally better, especially for women.
Triglycerides
A type of fat in your blood. High levels are an early warning sign of insulin resistance and heart disease risk.
ApoB
A protein on harmful cholesterol particles. Many longevity doctors consider it the single best predictor of heart disease risk.
Metabolic
HbA1c
Your blood sugar average over the past 2–3 months. One of the most important metabolic markers for longevity.
Fasting Glucose
Your blood sugar level after an overnight fast. A basic but important check on how well your body handles sugar.
Fasting Insulin
One of the earliest warning signs of metabolic problems — often elevated years before blood sugar rises.
Inflammatory
hs-CRP
A sensitive marker of inflammation in your body. Chronic low-grade inflammation is linked to nearly every age-related disease.
Homocysteine
An amino acid in your blood that, at high levels, is linked to heart disease, stroke, and brain health problems. B vitamins help keep it low.
Hormonal
TSH (Thyroid)
The main marker of thyroid function. Your thyroid controls your metabolism, energy, mood, and weight — and problems are very common in women.
Estradiol (Estrogen)
The main form of estrogen. It protects your bones, heart, and brain — and understanding it is essential during perimenopause and menopause.
DHEA-S
A hormone that naturally drops with age. It supports energy, immune function, and is sometimes called an 'anti-aging' hormone.
Cortisol
Your body's main stress hormone. A healthy cortisol rhythm is essential for sleep, energy, weight management, and immune health.
Fitness
VO2 Max
How well your body uses oxygen during exercise. Considered the single best predictor of how long you'll live.
Resting Heart Rate
How many times your heart beats per minute at rest. A lower number usually means a stronger, more efficient heart.
Nutritional
Vitamin D
One of the most common deficiencies worldwide. Vitamin D supports your bones, immune system, mood, and muscle strength.
Ferritin
Your body's iron storage marker. Low ferritin is one of the most common causes of fatigue in women — even when standard iron tests look normal.
Magnesium (RBC)
Involved in over 300 processes in your body — from sleep to muscle recovery. Most people don't get enough, and standard blood tests often miss it.
Omega-3 Index
The percentage of omega-3 fats in your blood cells. An index above 8% is linked to significantly lower heart disease and inflammation risk.
