Total Cholesterol

Total cholesterol measures the sum of all cholesterol types in your blood. While necessary for cell function, elevated levels are associated with increased cardiovascular risk and shortened lifespan.

LDL (Low-Density Lipoprotein)

Often referred to as “bad” cholesterol, high LDL contributes to arterial plaque buildup. Lower levels are associated with reduced risk of heart attack and stroke.

HDL (High-Density Lipoprotein)

HDL is the “good” cholesterol that helps remove LDL from the bloodstream. Higher levels are protective and linked to better heart and metabolic health.

Lipoprotein(a)

Lp(a) is a genetically influenced cholesterol particle that increases cardiovascular risk independent of other lipids. Early detection is key, as levels don’t respond well to lifestyle changes.

This test measures magnesium inside red blood cells, where it’s biologically active. Magnesium supports deep sleep, muscle recovery, and nervous system balance—key for long-term vitality.

Vitamin D

Vitamin D regulates sleep quality, immune strength, and hormone function. Optimal levels are associated with lower risk of chronic disease and improved mood and sleep.

Serum Ferritin

Ferritin reflects stored iron levels. Both low and high ferritin can disrupt sleep, impair energy levels, and are linked to aging-related decline in endurance and cognition.

Total Iron Binding Capacity (TIBC)

TIBC assesses your blood’s ability to transport iron. Abnormal levels may indicate poor nutrient absorption or chronic inflammation, both of which can impair sleep and recovery.

GGT reflects oxidative stress and liver detox capacity. Even slight elevations are linked to increased risk of cardiovascular disease and all-cause mortality.

Testosterone

Testosterone supports metabolism, energy, muscle mass, and mood. Balanced levels in men and women are associated with healthy aging and preserved vitality.

Uric Acid

While a natural antioxidant in small amounts, high uric acid contributes to inflammation and metabolic dysfunction. Elevated levels are linked to gout, kidney strain, and cardiovascular risk.

Alkaline Phosphatase

This enzyme supports bone and liver health but can indicate dysfunction when outside optimal range. Elevated levels are associated with inflammation, oxidative stress, and aging-related conditions.

Homocysteine

Homocysteine is an amino acid linked to vascular inflammation and brain aging. Elevated levels are associated with increased risk of dementia, stroke, and cognitive decline.

Cortisol (Morning)

Morning cortisol should peak shortly after waking, supporting alertness and metabolic activation. Blunted or elevated responses are linked to fatigue, mood imbalance, and accelerated aging.

Cortisol (Afternoon)

Afternoon cortisol should gently taper. Dysregulation may reflect chronic stress or adrenal fatigue, both of which impair cognitive function and long-term vitality.

Cortisol (Night)

Nighttime cortisol should be at its lowest to allow for deep sleep and cellular repair. Elevated evening cortisol disrupts sleep architecture and speeds biological aging.

24-Hour Urinary Cortisol

This test captures your total cortisol output over a day. Both high and low values may signal burnout, chronic stress, or poor resilience—core drivers of cognitive aging.

Estradiol

Estradiol is the primary form of estrogen, crucial for reproductive, cognitive, and cardiovascular health. Balanced levels support bone density, mood, and healthy aging across sexes and life stages.

Progesterone

Progesterone regulates mood, sleep, and menstrual health. Inadequate or misaligned levels can lead to fatigue, anxiety, and disrupted hormonal signaling over time.

TSH (Thyroid-Stimulating Hormone)

TSH controls your thyroid, the master regulator of metabolism. Both high and low levels are linked to fatigue, weight gain, cognitive dysfunction, and shortened lifespan.

Calcium (Serum & Ionized)

Calcium is essential for muscle function, bone health, and nerve signaling. Tight regulation is critical—both low and high levels are linked to heart disease, osteoporosis, and mortality risk.

DHEA-S

DHEA-S is a longevity hormone that supports immune balance, mood, and stress resilience. Optimal levels are associated with delayed biological aging and better physical performance.

Ferritin

Ferritin reflects iron storage and oxygen-carrying capacity. Low levels impair stamina and recovery, while excess iron is linked to oxidative stress and chronic disease.

Iron

Iron is essential for delivering oxygen to tissues during activity. Both deficiency and overload impact endurance, fatigue, and long-term cardiovascular health.

MCH measures the average amount of hemoglobin per red blood cell. It affects oxygen delivery, and suboptimal values may indicate anemia or nutrient imbalance that reduces exercise capacity.

MCHC (Mean Corpuscular Hemoglobin Concentration)

MCHC evaluates the density of hemoglobin in red cells. It’s used to detect subtle deficiencies that can reduce energy levels and impair aerobic performance.

MCV (Mean Corpuscular Volume)

MCV assesses red blood cell size, helping detect early nutrient imbalances. It’s often one of the first indicators of low endurance potential due to anemia or inflammation.

RBC (Red Blood Cell Count)

Red blood cells transport oxygen throughout the body. Adequate levels are crucial for energy, brain function, and physical performance—strong predictors of healthy aging.

Platelet Count

Platelets are key to clotting and healing. Both high and low counts may signal inflammation, immune stress, or recovery challenges that reduce resilience over time.

Free Testosterone

Free testosterone is the active form of testosterone that directly affects muscle mass, strength, mood, and energy. Optimal levels support vitality, physical performance, and metabolic health as you age.

SHBG (Sex Hormone-Binding Globulin)

SHBG controls the availability of sex hormones like testosterone and estrogen. Imbalances can limit hormonal effectiveness, impacting muscle development, recovery, and longevity.

VO₂ Max

VO₂ max measures your body’s ability to deliver and utilize oxygen during exercise. It is one of the strongest predictors of cardiovascular health, physical capacity, and all-cause mortality.

Percent Body Fat

Body fat percentage reflects the balance between fat and lean mass. Maintaining optimal levels reduces chronic disease risk, supports metabolic health, and improves functional longevity.

SMM to FFM Ratio (Skeletal Muscle Mass to Fat-Free Mass)

This ratio highlights the quality of lean mass. A higher percentage of skeletal muscle is linked to better mobility, metabolic function, and protection against age-related frailty.

Waist-to-Hip Ratio

Waist-to-hip ratio is a strong indicator of visceral fat and cardiovascular risk. Lower ratios are correlated with longer lifespan and reduced risk of metabolic syndrome.

BMI (Body Mass Index)

BMI provides a general gauge of weight relative to height. While imperfect, staying in the optimal range is associated with lower disease burden and improved healthspan.

Albumin

Albumin is a protein produced by the liver that reflects overall nutritional and inflammatory status. Higher levels within the normal range are associated with lower mortality and greater resilience.

Total Serum Protein

This marker captures the balance of albumin and globulins in your blood. Abnormal levels can indicate chronic inflammation, malnutrition, or kidney dysfunction—each of which can compromise longevity.

Hemoglobin

Hemoglobin carries oxygen in red blood cells. Low levels impair energy and organ function, while excessive levels may indicate underlying disease or poor oxygen regulation.

Hematocrit

Hematocrit measures the proportion of blood made up of red cells. Optimized levels support endurance, brain function, and cardiovascular health.

eGFR (Estimated Glomerular Filtration Rate)

eGFR reflects kidney filtration capacity. A declining eGFR with age signals increased risk of hypertension, toxin buildup, and chronic illness.

Cystatin C

A sensitive marker of kidney function and cardiovascular risk. Unlike creatinine, it’s not influenced by muscle mass, making it useful in aging populations.

BUN (Blood Urea Nitrogen)

BUN reflects how well your kidneys excrete waste. Both high and low levels are linked to nutrient imbalances, dehydration, and impaired longevity.

Vitamin B12

Essential for DNA repair, nerve health, and red blood cell production. Subclinical deficiencies are common with age and linked to fatigue, cognitive decline, and frailty.
