Energy
The currency of life. Energy depends on mitochondrial function, thyroid output, nutrient status, sleep quality, and blood sugar stability. Fatigue is a symptom with many causes. Finding your root cause transforms everything.
Common Causes of Low Energy
Thyroid Dysfunction
Hypothyroidism is common. Check full panel including T3, rT3. Not just TSH.
Iron Deficiency
Even without anemia. Check ferritin. Women especially vulnerable.
Poor Sleep
Quality matters more than quantity. Sleep apnea undiagnosed. Poor sleep hygiene.
Blood Sugar Swings
Highs and crashes. Reactive hypoglycemia. Insulin resistance.
Mitochondrial Issues
Nutrient deficiencies, toxins, age. Power plants not working.
Chronic Infection
EBV reactivation, Lyme, gut infections. Immune system draining energy.
How Energy Is Made
Glycolysis
Glucose to pyruvate. Cytoplasm. Quick energy. 2 ATP.
Krebs Cycle
Mitochondrial matrix. Generates electron carriers. Multiple B vitamins needed.
Electron Transport
Inner mitochondrial membrane. Majority of ATP made here. CoQ10 essential.
Supporting Energy
B Vitamins
Cofactors for energy production. B1, B2, B3, B5 especially. Activated forms.
CoQ10
Electron transport chain. Ubiquinol form better absorbed. 100-300mg.
Magnesium
ATP must bind magnesium. 300+ enzyme reactions. Most are deficient.
Iron (if low)
Oxygen transport to mitochondria. Test before supplementing. Ferritin 70-100.
Sleep Optimization
7-9 hours. Consistent timing. Dark, cool room. Address apnea.
Blood Sugar Balance
Protein with meals. Reduce refined carbs. Avoid constant snacking.
