Fatigue is a symptom, not a root cause. Treating the symptom (e.g., with energy drinks) worsens the problem. Identifying and addressing the root cause is key to eliminating fatigue.
Lack of sleep negatively impacts cognitive function, leading to difficulty concentrating, and severely affects blood sugar, increasing cravings. Solutions include long walks in nature, stretching before bed, dimming lights, and avoiding snacking before sleep.
Fluctuating blood sugar, often due to insulin resistance, starves cells of fuel despite available food, causing fatigue (like in diabetics). Symptoms include needing a nap after meals. The simple solution is to cut out carbs and reduce meal frequency by avoiding snacks.
Hypothyroidism leads to fatigue because T3 thyroid hormone, crucial for energy production in mitochondria, is insufficient. Symptoms include cold feet. Autoimmune hypothyroidism (90%) can be helped by selenium, while non-autoimmune issues often benefit from iodine and zinc.
Excess histamines can overstimulate the brain, causing irritated tiredness, allergy-like symptoms, and difficulty sleeping. Foods high in histamines (cheese, smoked meats, fermented foods) can aggravate this. Supplements specifically for histamines can help.
Reactivation of dormant viruses (e.g., due to stress, low vitamin D, or junk food) drains the immune system, causing delayed post-exertion fatigue. Solutions include stress reduction, 20,000 IUs of Vitamin D3 (with K2 and magnesium).
Deficiencies in sodium or potassium impair the sodium-potassium pump, which generates electrical energy for the nervous system and muscles, leading to muscle fatigue and lack of energy. People are often more deficient in potassium (requiring 4,700 mg daily), which can be boosted by eating avocados, large salads, or electrolyte drinks. Refined carbohydrates deplete potassium.
Anemia (iron or B12 deficiency) prevents red blood cells from carrying enough oxygen, hindering energy production in mitochondria. For menstruating women, red meat or liver pills help; for others, copper deficiency often underlies the iron imbalance. Lack of stomach acid can also impede nutrient absorption, remediable with betaine hydrochloride.
Magnesium deficiency, hard to detect with standard blood tests as most is intracellular, causes fatigue, cramps, and insomnia. Magnesium is vital for many bodily functions. Supplementing with magnesium glycinate before bed can help relax muscles and promote sleep.
Excessive carbohydrate intake depletes B1 (thiamine), preventing cells from using fuel for energy, instead shunting it to fat storage. Symptoms include nervous energy, lactic acid buildup, and fatigue after eating carbs. The recommended supplement, after diet correction, is allithiamine from garlic.
Lack of sun exposure, especially its infrared energy, impairs mitochondrial energy production. This, alongside vitamin D deficiency, causes lethargy, apathy, lower back pain, and pelvic discomfort. Increasing sun exposure and supplementing 20-30,000 IUs of Vitamin D (with K2 and magnesium) is crucial.
Mold exposure triggers immune reactions, draining energy. General inflammation, whether from mold or autoimmune disease, causes fatigue. Increasing vitamin D (20-30,000 IUs daily with K2 and magnesium) can significantly reduce inflammation.
Long COVID is an immune issue where the body overworks, leading to constant fatigue, brain fog, and sensory overwhelm. Remedies include NAC (N-acetylcysteine), vitamin D3, magnesium glycinate, zinc, and coenzyme Q10.
Insufficient amino acids (protein) hinder mitochondria function and essential bodily processes like enzyme activity, antioxidant production, repair, and muscle maintenance. This leads to brain fog, fatigue, and severe post-exercise fatigue. Solution: consuming more high-quality animal protein with every meal and lowering carbs.
Adrenal fatigue, stemming from chronic stress, disrupts circadian rhythms (tired all day, awake at night). Symptoms include salt cravings. Increased sea salt intake helps calm adrenals; electrolyte powder with potassium and ashwagandha can also support adrenal function. Long walks in nature are recommended over high-intensity exercise before bed.
