Hair mineral analysis testing analyses a small sample of hair to determine the levels of various minerals and trace elements in the body.

Vitamin and nutrient testing measures the levels of essential micronutrients in your blood — vitamins, minerals, and trace elements that your body needs in small amounts but cannot function without. Common tests include B12 (critical for nerve function and red blood cell production), folate (essential for DNA synthesis and especially important in pregnancy), zinc (immune function, wound healing), magnesium (involved in 300+ enzymatic reactions), and selenium (thyroid function, antioxidant defense). Deficiencies are more common than most people realize, particularly in B12 (affecting up to 20% of older adults), vitamin D, iron, and magnesium. Symptoms are often vague — fatigue, brain fog, poor sleep — making testing the only reliable way to identify specific gaps.

Varies by specific test
Sample Type

Turnaround
2–5 business days
Common Use
Deficiency screening, supplementation guidance

Who Is This For?

Vegetarians and vegans (at higher risk of B12, iron, and zinc deficiency). Older adults, as nutrient absorption decreases with age. Anyone on restrictive diets or with digestive conditions affecting absorption. People experiencing unexplained fatigue, brain fog, poor wound healing, or hair loss. Athletes with high nutrient demands from training.

What's Included

Vitamin B12
Folate (vitamin B9)
Additional vitamins and minerals (varies by panel)

Preparation Required

Fasting for 8–10 hours is recommended for some nutrient tests but not all — check with your provider. Continue taking your regular supplements unless told otherwise (the test measures your steady-state levels). Morning draws are preferred for consistent results.

Biomarkers Tested

18
Aluminium µg/L

A non-essential metal with no biological function. Elevated aluminium can result from occupational exposure, dialysis, or antacid use. Chronic exposure is associated with bone disease and neurological effects.

Arsenic µg/L

A toxic metalloid found in contaminated water, rice, seafood, and industrial settings. Chronic low-level exposure increases cancer risk and damages the cardiovascular, nervous, and endocrine systems. Testing distinguishes organic (dietary) from inorganic (toxic) forms.

Cadmium µg/L

A highly toxic heavy metal primarily from cigarette smoke, industrial exposure, and contaminated food. Cadmium accumulates in the kidneys and liver, causing kidney damage, bone loss, and increased cancer risk with chronic exposure.

Lead µg/dL

A toxic heavy metal with no safe level of exposure. Even low blood lead levels cause cognitive impairment, kidney damage, and cardiovascular effects. Sources include old paint, contaminated water, occupational exposure, and certain imported products.

Mercury µg/L

A toxic heavy metal found in certain fish (methylmercury), dental amalgams, and industrial sources. Mercury targets the nervous system, causing tremors, cognitive changes, and sensory impairment. Fish consumption is the primary source for most people.

Nickel µg/L

A metal that causes allergic contact dermatitis in sensitised individuals. Occupational or dietary exposure to elevated nickel levels can affect the respiratory system and kidneys. Common sources include jewellery, coins, and certain foods.

Silver µg/L

A metal measured in toxicology panels. Chronic exposure to silver compounds (from colloidal silver supplements or occupational sources) can cause argyria, a permanent blue-grey discoloration of the skin.

Tin µg/L

A metal found in canned foods, solder, and industrial materials. While small amounts of inorganic tin are relatively non-toxic, high levels can cause gastrointestinal irritation. Organotin compounds are more toxic and affect the immune and nervous systems.

Chromium µg/L

An essential trace mineral in its trivalent form (Cr³⁺), important for insulin signalling and glucose metabolism. Hexavalent chromium (Cr⁶⁺) from industrial exposure is carcinogenic. Testing measures total chromium levels.

Copper µg/dL

A trace mineral essential for iron metabolism, connective tissue formation, and antioxidant defense. The copper/zinc ratio is an emerging marker of inflammation and oxidative stress. Both deficiency and excess can cause problems.

Iron (Fe) µg/dL

A mineral essential for oxygen transport (in hemoglobin), energy production, and immune function. Serum iron measures the amount circulating in blood, but ferritin and TIBC provide a more complete picture of iron status.

Manganese µg/L

An essential trace mineral needed for bone formation, blood clotting, and antioxidant defense (via superoxide dismutase). Excess manganese, typically from occupational inhalation, causes manganism — a Parkinson's-like neurological condition.

Selenium µg/L

A trace mineral crucial for thyroid hormone metabolism, antioxidant defense (via selenoproteins), and immune function. Selenium deficiency can impair thyroid function and increase susceptibility to viral infections.

Zinc µg/dL

An essential trace mineral involved in immune function, wound healing, DNA synthesis, and testosterone production. Zinc deficiency impairs immune response, delays wound healing, and can cause hair loss and taste changes.

Calcium mg/dL

The most abundant mineral in the body, essential for bone health, muscle contraction, nerve function, and blood clotting. Blood calcium is tightly regulated by parathyroid hormone and vitamin D. Abnormal levels can indicate parathyroid disorders.

Magnesium mg/dL

Involved in over 300 enzymatic reactions including energy production, muscle function, and nerve signaling. Magnesium deficiency is common and associated with muscle cramps, anxiety, insomnia, and increased cardiovascular risk.

Vitamin B12 pg/mL

Essential for nerve function, DNA synthesis, and red blood cell formation. B12 deficiency can cause anemia, neuropathy, fatigue, and cognitive impairment. Common in vegans, vegetarians, older adults, and those taking metformin or acid-reducing medications.

Folate (Vitamin B9) ng/mL

Essential for DNA synthesis, cell division, and red blood cell formation. Folate deficiency causes megaloblastic anemia and, during pregnancy, increases the risk of neural tube defects. Works closely with vitamin B12.
