22 Biomarkers
Cortisol

Mapped at four points across the day to reveal your natural stress rhythm, not just a single level, offering insight into energy, sleep, and resilience.

Estrogen

Tracks how your body produces, uses, and clears estrogen, offering insight into cycle regularity, mood, and hormone balance.

Testosterone

Measures both free and total testosterone, relevant to energy, muscle maintenance, libido, and overall hormonal balance.

Progesterone

Reflects ovulation and luteal phase function, often connected to mood, sleep quality, and cycle regularity.

DHEA

An adrenal hormone that acts as a building block for other hormones, used as a marker of adrenal reserve and long-term stress load.

Estrone (E1)

One of the three main forms of estrogen, often the dominant type after menopause.

Estradiol (E2)

The most active form of estrogen, involved in cycle regularity, bone health, and mood.

Estriol (E3)

A weaker form of estrogen that rises significantly during pregnancy and reflects estrogen balance overall.

2-OH-Estrogen

A protective estrogen metabolite associated with healthy estrogen clearance.

4-OH-Estrogen

An estrogen metabolite worth monitoring in higher amounts, since it's linked to oxidative stress.

16-OH-Estrogen

A more stimulating estrogen metabolite, relevant to overall estrogen balance and detox pathways.

Androsterone

A testosterone metabolite that reflects how your body is breaking down and clearing androgens.

Etiocholanolone

Another androgen metabolite, used alongside androsterone to assess hormone clearance pathways.

5α-DHT

A potent testosterone byproduct linked to hair, skin, and prostate health.

Cortisol Awakening Response

Measures the natural cortisol spike in the first hour after waking, a key marker of adrenal responsiveness.

Free Cortisone (4-Point)

The inactive counterpart to cortisol, tracked alongside it to understand how your body converts and regulates stress hormones.

Cortisol Metabolites

Reflects the total amount of cortisol your body produces and clears each day, a broader view than free cortisol alone.

8-OHdG (Oxidative Stress)

A marker of oxidative damage to DNA, used as a general indicator of cellular stress load.

Melatonin (6-OHMS)

The main melatonin metabolite, offering insight into your sleep-wake cycle and nighttime hormone production.

Vitamin B12 Marker

An organic acid marker used to flag possible vitamin B12 insufficiency.

Vitamin B6 Marker

An organic acid marker used to flag possible vitamin B6 insufficiency.

Glutathione Marker

Reflects your body's levels of glutathione, a key antioxidant involved in detoxification.

HTMA: Minerals

Hair Tissue Mineral Analysis
20 Biomarkers
Sodium

Reflects adrenal activity and how your body manages stress and fluid balance.

Magnesium

Involved in hundreds of processes, including energy production, muscle relaxation, and nervous system regulation.

Potassium

Works alongside sodium to support cellular function, muscle activity, and thyroid-adrenal balance.

Calcium

Reflects far more than bone health, offering insight into metabolic rate and nervous system activity.

Copper

Involved in energy production, connective tissue, and neurotransmitter balance; levels can run high or low depending on individual patterns.

Zinc

Supports immune function, digestion, and hormone production, and is often assessed alongside copper for balance.

Phosphorus

Works with calcium in bone health and energy metabolism at the cellular level.

Iron

Reflects longer-term iron status as it relates to energy production and oxygen transport.

Manganese

A trace mineral involved in antioxidant activity and connective tissue formation.

Chromium

Plays a role in blood sugar regulation and how your body responds to insulin.

Selenium

Supports thyroid hormone conversion and acts as an antioxidant.

Boron

A trace mineral involved in bone health and hormone metabolism.

Lead

A toxic heavy metal that can accumulate over time and interfere with normal mineral function.

Mercury

A toxic heavy metal often linked to dietary exposure, screened for as part of overall toxic burden.

Cadmium

A toxic heavy metal associated with environmental and occupational exposure.

Arsenic

A toxic element sometimes found in water and food sources, tracked as part of overall exposure.

Aluminum

A common environmental metal, tracked to assess your body's overall toxic mineral burden.

Calcium/Magnesium Ratio

Reflects thyroid and adrenal activity; an imbalance here can point to a slower or faster metabolic rate.

Sodium/Potassium Ratio

A key marker of adrenal stress response and how your body is handling ongoing stress.

Zinc/Copper Ratio

Reflects the balance between these two minerals, relevant to immune function and hormone metabolism.

GI-MAP: Gut Health

Gastrointestinal Microbial Assay Plus
18 Biomarkers
H. Pylori

Screens for this common bacteria, linked to digestive discomfort, bloating, and long-term irritation of the gut lining.

Candida

Flags overgrowth of this naturally occurring yeast, which can contribute to bloating, fatigue, and sugar cravings when out of balance.

Intestinal Markers

Includes markers of inflammation and gut lining integrity, offering a picture of how well your digestive system is functioning day to day.

Campylobacter

A bacterial pathogen linked to acute digestive upset and, in some cases, longer-term gut irritation.

Salmonella

A bacterial pathogen associated with foodborne illness and digestive symptoms.

Shigella

A bacterial pathogen that can cause digestive inflammation and discomfort.

E. coli (Pathogenic Strains)

Screens for disease-causing strains of E. coli, distinct from the beneficial strains normally found in the gut.

Giardia

A common parasite linked to bloating, digestive upset, and nutrient malabsorption.

Cryptosporidium

A parasite that can disrupt normal digestion and nutrient absorption.

Entamoeba Histolytica

A parasite associated with digestive discomfort and, in some cases, more significant gut irritation.

Blastocystis Hominis

A common organism that can be harmless or contribute to digestive symptoms depending on the individual.

Norovirus

A common virus linked to acute digestive upset.

Zonulin (Intestinal Permeability)

A marker of gut lining integrity, often referenced in discussions of "leaky gut."

Secretory IgA (Immune Function)

Reflects the strength of your gut's immune defenses against pathogens and irritants.

Elastase-1 (Pancreatic Function)

Indicates how well your pancreas is producing the enzymes needed for digestion.

Calprotectin (Inflammation)

A marker of inflammation in the digestive tract, useful for distinguishing inflammatory from non-inflammatory gut issues.

Beta-Glucuronidase (Estrogen Recycling)

An enzyme that affects how estrogen is recycled through the gut, connecting gut health to hormone balance.

Steatocrit (Fat Malabsorption)

Reflects how well your body is digesting and absorbing dietary fat.
