Why You're Exhausted After 70 — The Mineral Deficiency Standard Blood Tests Miss

Your doctor ran blood work. Everything came back normal. But you are still exhausted every single morning. Here is what most seniors are never told: the standard panel does not test the four specific deficiencies most consistently driving persistent fatigue in adults over 70. In this video, Dr. Elena Pierce covers: ✔ Iron deficiency WITHOUT anemia — why normal hemoglobin doesn't mean normal ferritin, and why ferritin below 50 mcg/L produces fatigue through mitochondrial and neurotransmitter pathways ✔ Vitamin B12 and the "grey zone" — why a serum B12 between 200-350 pg/mL can still mean functional deficiency (methylmalonic acid as the real test) ✔ How atrophic gastritis affects 30% of adults over 70 and silently blocks B12 absorption regardless of diet ✔ CoQ10 — the mitochondrial energy carrier that declines with age AND with statin use simultaneously ✔ Zinc's role in thyroid hormone conversion — how subtle zinc deficiency produces functional hypothyroid fatigue invisible on a standard TSH ✔ The 4 specific test names to bring to your next appointment — and optimal target ranges for adults over 70 📋 Research sources: — British Journal of General Practice (ferritin and fatigue without anemia) — Neurology (B12 deficiency, brain atrophy, and cognitive fatigue) — Journal of Nutritional Science and Vitaminology (CoQ10 and fatigue in 70+) — Journal of Nutrition (zinc deficiency prevalence in adults 65+) ⚠️ Do not begin iron, B12, CoQ10, or zinc supplementation without physician guidance. Excess iron and zinc carry documented risks. Interactions with existing medications must be evaluated individually. 💬 Comment "GETTING ALL FOUR TESTED" to commit to bringing these test names to your next appointment. 💬 Comment "ALREADY IDENTIFIED ONE" to share your experience and results. 💬 Comment "CHRONIC FATIGUE IS REAL" if this describes your experience. 🔔 Subscribe — evidence-based senior health every week.
