Ferritin at 14 is technically above the conventional lower limit of 12. It's also below the functional threshold of 50–70 ng/mL where thyroid peroxidase activity and mitochondrial iron-sulfur cluster assembly become impaired. That's a fatigued patient being told their labs are normal. I use functional reference ranges because the conventional ranges describe populations, not optimal physiology. Free T3 in the lower quartile, ferritin below 50, RBC magnesium below functional threshold, vitamin D at 20 — these are the findings that explain why a patient's fatigue has persisted for three years with a normal annual checkup.
How Fatigue Treatment Works
Fatigue treatment begins with comprehensive functional medicine testing — a panel that goes far beyond a standard "check for anemia" workup. Dr. Hendry orders full thyroid panel, comprehensive metabolic panel, CBC with differential, ferritin (iron stores), vitamin D, B12, methylmalonic acid (functional B12), folate, magnesium, inflammatory markers, cortisol curve, and additional testing as indicated. Acupuncture addresses the constitutional pattern (most commonly Spleen Qi Deficiency or Kidney Yang Deficiency) while functional medicine addresses the identified nutritional or hormonal drivers.

Targeted Metabolic Investigation vs. Normal Labs Dismissal of Fatigue
The most common experience reported by fatigued patients before reaching our practice is a variation of the same conversation: labs were ordered, labs returned normal, and the patient was told fatigue is likely related to stress or sleep hygiene. This response is not negligent; it reflects the genuine limitations of conventional reference ranges, which are derived from population statistics rather than from studies correlating biomarker levels with metabolic function. A 47-year-old woman presents with three years of fatigue that has not improved with sleep optimization or iron supplementation. Her conventional panel shows TSH 2.4 mIU/L, hemoglobin 12.8 g/dL, ferritin 14 ng/mL, and a metabolic panel within range. Ferritin at 14 ng/mL is technically above the conventional lower limit of 12 but is below the functional threshold of 50-70 ng/mL required for adequate thyroid peroxidase activity and mitochondrial iron-sulfur cluster assembly. Free T3 measures 2.4 pg/mL, in the lower quartile of a range where clinical hypothyroid symptoms commonly emerge below 3.0 pg/mL. RBC magnesium, which reflects intracellular rather than serum status, is below the functional threshold. Targeted repletion of ferritin, magnesium, and T3-supporting nutrients alongside acupuncture to reduce cortisol-driven T4-to-T3 conversion impairment produces objective improvement where reassurance alone did not.
Research & Evidence
Persistent fatigue without a single identified cause represents one of the most diagnostically challenging presentations in primary care, yet the biological contributors are identifiable when the appropriate tests are ordered. Naviaux et al. (PNAS. 2016) demonstrated detectable metabolomic abnormalities in patients with unexplained fatigue, pointing to impaired mitochondrial oxidative phosphorylation and purine metabolism as upstream drivers. Hoermann et al. (Eur Thyroid J. 2019) established that TSH within the conventional reference range is an insufficient indicator of cellular thyroid hormone sufficiency; free T3, the active thyroid hormone at mitochondrial receptors, requires direct measurement. Hannibal and Bishop (Phys Ther. 2014) documented that HPA axis dysfunction produces a flat or inverted cortisol curve, depriving cells of the glucocorticoid signaling required for mitochondrial biogenesis and glucose utilization efficiency. Magnesium, coenzyme Q10, and ferritin deficiencies each independently impair ATP synthesis at different points in the electron transport chain, and all are frequently within conventional reference ranges while remaining below functional thresholds. Our fatigue protocol includes free T3, free T4, reverse T3, a 4-point salivary cortisol curve, ferritin, magnesium RBC, coenzyme Q10, and a comprehensive organic acid panel to identify mitochondrial bottlenecks before attributing fatigue to lifestyle factors.
Your First Appointment
Describe your fatigue pattern: constant vs. intermittent, morning vs. afternoon vs. evening worst, whether it is worsened by exertion (post-exertional malaise), and associated symptoms (brain fog, muscle pain, sleep issues). Bring any prior fatigue-related lab work.
Why Dr. Hendry for Fatigue Treatment
Dr. Hendry's functional medicine investigation consistently identifies treatable drivers of fatigue that standard medical workups miss — because he uses functional reference ranges and orders tests that conventional primary care does not routinely include.
