Essential Nutrients Panel (6 Markers)
A single blood sample measures the six most fundamental — and most often overlooked — nutrients: vitamin D3, vitamin B12, folate, ferritin, coenzyme Q10 and vitamin C. More objective than a dietary questionnaire and closer to what your body has actually absorbed than a supplement label, it is the lowest-threshold entry point into functional medicine.
Worth testing if:
- You take supplements but aren't sure you're taking the right ones, at the right dose
- Children and adolescents, whose nutrient demands exceed an adult's
- Older adults: absorption declines, and long-term medication depletes nutrients
- You eat out often, or your fruit and vegetable intake is low
- Vegetarians and vegans: B12, iron and vitamin D are the most common gaps
- You tire easily, or deal with brain fog, hair loss or fluctuating immunity
- You want to start functional medicine but don't know which test to begin with
What this test is for
A blood sample measures six of the most fundamental nutrients at once: vitamin D3, vitamin B12, folate, ferritin, coenzyme Q10 and vitamin C. More objective than a dietary questionnaire and closer to what your body has actually absorbed than a supplement label, it is an entry-level tool for assessing your nutrient reserves.
This panel is built for nutritional needs, and it is the lowest threshold into functional medicine. Those capsules you swallow every day — do they actually become a concentration your body can use? Whether you are taking enough, absorbing it well, or overdoing it are questions a food diary cannot answer. Only blood values can.
These six were not picked at random. Vitamin B12, folate and ferritin drive haematopoiesis and methylation, the most common source of fatigue, brain fog and hair loss; vitamin D3, coenzyme Q10 and vitamin C hold up immune regulation, energy metabolism and antioxidant defence. They act on one another — read one alone and you can easily misjudge it; read them together and the gap becomes visible.

Frequently asked questions
I take a multivitamin every day — do I still need this?
Swallowing it is not the same as using it. The same dose can produce blood levels that differ several-fold between people, depending on gut absorption, medication, genotype and rate of consumption. Multivitamin doses are usually conservative — enough to avoid deficiency, but not necessarily enough to be sufficient.
Blood levels tell you whether your dose is genuinely adequate.
I don't feel unwell. Do I need to test?
Nutrient depletion is gradual. By the time fatigue, brain fog, hair loss or fluctuating immunity appear, reserves have usually been low for some time — and those symptoms are far too easily written off as "not enough sleep" or "too much stress".
Establish a baseline first, so change becomes visible.
Which markers matter most for vegetarians?
Vitamin B12 occurs almost exclusively in animal foods and is the most common gap; ferritin comes next, as plant-based iron is absorbed far less efficiently; vitamin D depends on sun exposure. Read together, these three distinguish inadequate intake from an absorption problem.
This panel covers the three gaps vegetarians hit most often.
Is this suitable for children and older adults?
Yes, though the focus differs. Growing children have higher nutrient demands than adults, and a gap affects development. For older adults it is declining absorption, compounded by long-term medication — statins, for instance, directly inhibit the synthesis pathway for coenzyme Q10.
The same data reads differently at different ages.
Is more always better?
No. Vitamin D3 and coenzyme Q10 are fat-soluble and accumulate in excess; high ferritin may reflect iron overload or underlying inflammation. The goal for nutrients is the optimal range, not the highest number.
Testing prevents both under- and over-supplementation.
How is this different from the 68-marker core test?
The core test covers 68 markers across multiple body systems and includes an advisor report walkthrough and a personalized action plan. This six-marker panel is a single entry point — nutrient reserves only — suited to anyone meeting functional medicine for the first time, or tracking nutritional status on its own.
