Micronutrient Testing
A surprising share of 'unexplained' fatigue, poor recovery, low mood and brain fog traces to measurable micronutrient deficits — vitamin D, B12, ferritin, magnesium, zinc, omega-3s. Micronutrient testing replaces guess-based supplementation with numbers: test, correct the specific deficit at the right dose, then retest to confirm you've actually moved it.
Why test instead of just supplementing?
Because blind supplementation fails in both directions: you can spend years taking things you don't need while the one deficit driving your symptoms goes uncorrected — or push fat-soluble vitamins and minerals into excess. Testing turns supplements from a shelf of hope into a dosed correction.
Which deficiencies are most common?
Vitamin D leads by a wide margin, especially at northern latitudes and in anyone who works indoors. Iron (read via ferritin) is common in menstruating women and endurance athletes. B12 in plant-forward eaters and anyone on acid-reducing medication. Magnesium is under-consumed almost universally; omega-3 index is low in most Western diets.
What does a proper panel include?
Vitamin D (25-OH), B12 with methylmalonic acid where indicated, ferritin plus full iron studies, RBC magnesium, zinc, folate, and an omega-3 index. Read alongside homocysteine and hs-CRP — because inflammation distorts several of these markers and context prevents misreads.
Ferritin is an acute-phase reactant: it rises with inflammation, which can mask true iron deficiency. This is why panels are interpreted together, not marker by marker.
Serum level vs functional status — what's the difference?
A serum value tells you what's circulating; functional markers tell you whether cells have enough to do their job. B12 can be 'normal' in serum while methylmalonic acid reveals a functional deficit. Where the distinction changes the decision, we test the functional marker.
How does correction work at Integrated Wellness?
Each confirmed deficit gets a dose, a form (some forms absorb dramatically better) and a retest date — typically 12 weeks. Results stream into your Digital Twin so corrections are verified, doses adjusted, and resolved deficits move to annual monitoring instead of lifelong pill-taking.

My multivitamin covers me, right?
Usually not. Multis spread small doses across everything — often the wrong forms and far below correction doses for a true deficit. They're insurance against nothing in particular; testing finds the specific gap.
Can vitamin levels be too high?
Yes — vitamin D, iron, zinc and B6 all have real toxicity ceilings. Deficiency and excess are both measurable problems, which is exactly the argument for testing before dosing.
How fast do corrected deficits change how I feel?
Iron and B12 corrections often change energy within 4–8 weeks; vitamin D acts more slowly. The retest confirms the number moved — symptom change usually follows the biology.
Do I need this if my diet is excellent?
Diet quality lowers the odds but doesn't eliminate them — absorption issues, medications, training volume, sun exposure and genetics all create deficits that food alone can't always fix.
