Micronutrients, often referred to as vitamins and minerals, are vital to healthy development, disease prevention, and wellbeing. Vitamins are necessary for energy production, blood clotting and boosting our ability to fight infection from viruses and bacteria. Minerals play an essential role in growth, bone health, fluid balance and muscle contraction. This test can help you to identify micronutrient deficiencies so you can take steps to improve your health and immune system.

About this test

Micronutrients are vitamins and minerals needed by our bodies in very small amounts. Even though we only need small amounts, they are essential for normal bodily functions like fighting infections and keeping bones strong.

Symptoms of micronutrient deficiencies may include, but are not limited to:

  • Fatigue/low energy

  • Muscle aches or cramps

  • Hair loss

  • Slow wound healing

  • Bone pain or weakness

  • Irregular heartbeat

  • Poor night vision

Many people do not experience symptoms of micronutrient deficiencies. Taking supplements to correct micronutrient deficiencies can improve your health, but some micronutrients can be dangerous if you have too much. That is why it is important to have testing to find out which micronutrients you are lacking. This way, you can customize what supplements you actually need.

Schedule a time for our trained and certified concierge phlebotomist to come to your home or other designated location and collect your sample.

Almost one-third of people in the United States are at risk of at least one micronutrient deficiency, but some groups of people have a particularly high risk:

  • Pregnant people

  • People who are lactating (breastfeeding)

  • Adults over age 50

  • Obese individuals

  • You are experiencing symptoms of a deficiency*

  • People with chronic conditions that affect metabolism (like diabetes) or that affect the ability to absorb nutrients in the gut (like Crohn’s disease and ulcerative colitis)

  • People on strict diets (ex: vegetarian, vegan, keto, dairy-free, or gluten-free)

You should consider this test if you fit into any one of these categories. You can also take the micronutrient test if you simply want to identify areas for improvement of your overall health.

Please note: some personal products such as lotions and sunscreen contain zinc and therefore may impact the accuracy of your zinc test result. Additionally, supplements that contain biotin (B7) can impact your results. Wait at least 8 hours after your last dose before collecting your sample. 

The Micronutrient Test is not suitable for anyone under the age of 18. The vitamin B12 component of the test is not suitable for those under the age of 22, so if you are under the age of 22, you will not receive a vitamin B12 test result.

Vitamin B12

Vitamin B12 is a vitamin found mainly in animal products. It is involved in the creation of red blood cells, which carry oxygen around the body. Vitamin B12 is also involved in the normal growth and function of a healthy nervous system. Additional vitamin B12 is important for people who are breastfeeding.

Vitamin A

Vitamin A is essential for eye health. It also plays roles in the immune system, bone health, and maintaining the lining of blood vessels and the digestive tract. Carrots get their color from beta-carotene, a precursor that is converted into vitamin A in the body.

Vitamin D

Vitamin D helps the body absorb and retain calcium and phosphorus, which are essential for forming and maintaining strong bones and teeth. It also plays a role in regulating normal immune system function and maintaining a healthy heart and muscles. Vitamin D can be produced by the skin, but people with darker skin or people who live in climates with limited winter sunlight may not produce enough vitamin D from sun exposure.

Vitamin E

Vitamin E is an antioxidant that helps protect cells from damage. It helps with maintaining healthy skin and eyes, as well as the functions of the brain and immune system. Vitamin E is commonly found in plant-based oils, nuts, seeds, fruits, and vegetables.

Vitamin K

Vitamin K is found in green leafy vegetables like collard greens, kale, and spinach. It plays essential roles in blood clotting and bone health.


Hematocrit is a measure of the proportion of red cells in your blood. Red blood cells are essential for carrying oxygen through your body.

Hemoglobin A1C

The hemoglobin A1C test measures your average blood sugar levels over the past 3 months and can be used to diagnose pre-diabetes or diabetes. Hemoglobin is the oxygen-binding protein in your red blood cells. When sugar enters the blood, it can attach to hemoglobin. A hemoglobin A1C test measures the percentage of your red blood cells that have sugar-bound hemoglobin.


Magnesium is a mineral found in several plant foods like legumes, dark green leafy vegetables, nuts, seeds, whole grains, and fortified cereals. It is also found in meats and is an ingredient in laxatives. Magnesium regulates blood sugar and blood pressure and is essential for healthy and strong bones and teeth. It also acts as a conductor for muscle contraction and helps keep the heart beating steadily.


Zinc is an essential trace mineral that helps cells grow and multiply. This means that is important at times of growth including childhood, adolescence, pregnancy, and wound healing. Zinc is also necessary for maintaining a healthy immune system. Zinc is present in many foods, including animal products (meat, dairy products, eggs), whole grains, legumes, nuts, and seeds.


Copper is a naturally occurring metal and trace nutrient found in high-protein foods like organ meat, shellfish, fish, nuts, and seeds, as well as whole grains, and chocolate. Copper plays an essential role in producing energy for the body, absorbing iron to build red blood cells, and maintaining healthy immune and nervous systems.


Selenium is an essential trace mineral that helps make DNA and protect against cell damage and infections. It is also involved in reproduction and thyroid function. Selenium is found in common foods including bread, cereals, poultry, red meat, and eggs.


Arsenic is a toxin naturally found in soil and groundwater.


Mercury is a toxic liquid metal. In the United States, exposure to methylmercury mainly occurs through eating fish and shellfish.


Cadmium is a natural element found in tiny amounts in air, water, soil, and food. It is associated with an increased risk of lung cancer.


Dehydroepiandrosterone (DHEA) is a hormone naturally produced in the adrenal gland that helps produce testosterone and estrogen. Since DHEA declines with age, people use DHEA as an anti-aging treatment and to treat symptoms of menopause.


Folate, also called folic acid or vitamin B9, is a vitamin critical during pregnancy. It is also useful in producing DNA and RNA and metabolizing proteins.

Sex Hormone Binding Globulin

Sex hormone binding globulin (SHBG) is a protein made by your liver that binds estrogen, dihydrotestosterone (DHT), and testosterone to carry them through the blood. SHBG controls the amount of testosterone available for use in your body.
