Chronic Fatigue Recovery
About this protocol
Where to start
Get a medical workup first. Don''t self-treat persistent fatigue without ruling out the addressable causes. Common reversible findings: low ferritin (especially in menstruating women), subclinical hypothyroidism, sleep apnea, vitamin D deficiency, depression, glucose dysregulation.
Start with CoQ10 (ubiquinol) at 200-300 mg daily. The most-evidenced supplement for chronic fatigue syndromes — trials in ME/CFS and post-viral fatigue show meaningful symptom reductions over 12 weeks.
Add a NAD+ precursor (NR or NMN). The 2016 paper by Castro-Marrero showed CoQ10 + NADH combination improved CFS symptoms. NAD+ precursors are increasingly used in fatigue protocols though the evidence base is still preliminary.
Add iron ONLY if ferritin is confirmed low (<30-40 ng/mL). Iron deficiency without anemia is one of the most under-diagnosed reversible causes of fatigue in menstruating women.
Add vitamin B12 (methylcobalamin) at 1000 mcg daily. Low B12 is common, particularly in adults over 50, vegetarians, vegans, and chronic acid-suppressing medication users. Sublingual or methylated forms preferred.
Add magnesium glycinate at 300-400 mg before bed. Supports the multiple systems affected by chronic fatigue (sleep, muscle, mood).
Expect 12+ weeks of consistent stack + lifestyle for meaningful change. Chronic fatigue is a slow recovery.

Strongest evidence — the foundation of the stack.
CoQ10 (Ubiquinol)
200-300 mg daily, with a fat-containing mealCoQ10 supports mitochondrial energy production. Trials in ME/CFS, fibromyalgia, and post-viral fatigue syndromes show meaningful improvements in fatigue scores and quality of life over 12 weeks. The ubiquinol form has better bioavailability, especially in adults over 40. The Castro-Marrero 2015 trial in CFS used CoQ10 + NADH combination with positive results.[1, 2, 3]
NAD+ Precursor (NR or NMN)
250-500 mg daily, with breakfastNAD+ is a coenzyme essential for mitochondrial energy production. NAD+ levels decline with age and are particularly low in chronic fatigue states. Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are precursors that elevate cellular NAD+ levels. Human trial evidence is preliminary but mechanistically plausible. Treat as emerging — worth a structured 3-6 month trial with measurable endpoints.[4, 5, 6]
Add if needed
Add these only if the foundation isn't enough.
Iron (only if ferritin is confirmed low)
18-65 mg elemental with vitamin C, on empty stomach if toleratedIron deficiency without anemia is one of the most under-diagnosed causes of fatigue in menstruating women. Low ferritin (<30-40 ng/mL) often produces fatigue, exercise intolerance, hair shedding, restless legs, and brittle nails. Vaucher 2012 trial showed reduced fatigue with iron supplementation in nonanemic menstruating women with low ferritin. Test before supplementing — chronic over-supplementation is harmful.[7, 8]
Vitamin B12 (Methylcobalamin)
1000 mcg daily, sublingual or with breakfastLow B12 produces fatigue, cognitive symptoms, and neurological complaints often misattributed to other causes. Subclinical B12 deficiency is common in adults over 50 (reduced absorption), vegetarians/vegans, chronic metformin users, and long-term PPI/H2 blocker users. Methylcobalamin bypasses methylation steps and is preferable to cyanocobalamin for many people.[9, 10]
Experimental
Emerging evidence — try last, only if curious.
Magnesium Glycinate
300-400 mg elemental, before bedMagnesium supports the multiple systems affected by chronic fatigue: ATP production, muscle function, sleep architecture, nervous system regulation. Cox 1991 trial showed reduced CFS symptoms with magnesium supplementation in adults with low red blood cell magnesium. Most adults under-consume magnesium relative to needs.[11, 12]
Warnings
Lifestyle improvements
Get a thorough medical workup first
The labs that should be done: CBC + differential, ferritin, TSH + free T4 + free T3, vitamin B12, methylmalonic acid (better than B12 alone for true deficiency), homocysteine, 25-OH vitamin D, fasting glucose + insulin, HbA1c, lipid panel, ApoB, hsCRP, ESR, comprehensive metabolic panel, ANA (if autoimmune suspicion). Many primary care doctors order only TSH and CBC — politely request the full panel.
Rule out sleep apnea
Sleep apnea is the single most under-diagnosed cause of chronic fatigue. Symptoms include snoring, witnessed apneas, waking gasping, daytime sleepiness despite ''adequate'' sleep hours. A take-home sleep study is increasingly accessible.
Address depression honestly
Depression often presents as fatigue + loss of motivation + difficulty concentrating. It''s under-diagnosed in adults who don''t feel "sad" but feel exhausted. PHQ-9 is a simple screening tool. Therapy and SSRIs have strong evidence.
Sleep duration AND quality
7-9 hours is the right duration range. Track quality with a wearable or sleep diary. Persistent unrefreshing sleep despite adequate duration warrants further workup.
Gentle exercise — graded if ME/CFS
For most fatigue causes, regular moderate exercise improves symptoms. For ME/CFS specifically, post-exertional malaise (PEM) means traditional exercise can WORSEN symptoms — graded exercise therapy (GET) requires careful titration with PEM monitoring.
Address chronic infections
Long COVID, post-viral syndromes, chronic Lyme/coinfections, EBV reactivation — these all produce chronic fatigue patterns. If your fatigue began after an illness, mention this to your doctor.
Adequate protein and calories
Severely under-eating produces fatigue. Aim for 1.2-1.6 g/kg body weight protein daily and adequate total calories. Restrictive dieting amplifies fatigue.
Stress and trauma
Chronic stress and unprocessed trauma produce sustained sympathetic activation and fatigue. Therapy, EMDR, somatic work all have evidence.
Limit alcohol
Alcohol disrupts sleep architecture and amplifies next-day fatigue. Even ''moderate'' intake produces measurable next-day energy reduction.
Patience
Recovery from chronic fatigue is slow — typically months, not weeks. Avoid the trap of constantly changing supplements every 2-3 weeks looking for the magic bullet. Pick a protocol, give it 12 weeks, then reassess.
Find a fatigue-aware provider
General practitioners often dismiss persistent fatigue. Functional medicine, integrative medicine, sleep medicine, infectious disease, and rheumatology may be more thorough depending on suspected cause.

Morning Energy & Drive
energy
Morning fatigue and low drive — distinct from afternoon crashes (see Afternoon Energy) and chronic fatigue (see Chronic Fatigue Recovery) — is usually a circadian/HPA-axis pattern. Healthy adults experience a cortisol awakening response (CAR) in the first 30-45 minutes after waking; flattened or blunted CAR produces the "wake up still tired" feeling. The drivers are usually insufficient sleep duration, fragmented sleep architecture, vitamin and mineral gaps (especially B-complex and iron in women), thyroid issues, or chronic HPA-axis dysregulation. This stack supports the energy-production pathways: B-complex for cellular ATP production, L-tyrosine for dopamine/norepinephrine synthesis, rhodiola for stress-related fatigue, and CoQ10 for mitochondrial function. If you''re consistently exhausted on adequate sleep, get labs first: ferritin, TSH and free T4, fasting glucose, B12, 25-OH vitamin D. Many "I''m just tired" complaints have a reversible underlying cause.
Afternoon Energy
energy
The 2-4 PM crash is overdetermined: post-prandial blood sugar drop, residual sleep debt, accumulated cognitive load, late-morning caffeine wearing off. The honest answer is that supplements are downstream of fixing those — but a few have evidence for moderating fatigue. B-complex covers any subclinical deficiencies in energy-metabolism cofactors. Rhodiola has the most direct evidence for an anti-fatigue effect, especially under stress. CoQ10 helps mitochondrial energy production but the evidence is strongest in older adults, statin users, and chronic fatigue populations — less clear-cut in healthy young people.
Metformin Companion
medication· 3 shared ingredients
Metformin is the most-prescribed type 2 diabetes medication and is increasingly used off-label for prediabetes, PCOS, and even longevity research. The catch: long-term metformin use is associated with vitamin B12 deficiency in 5-30% of users — the exact mechanism involves reduced B12 absorption in the small intestine. B12 deficiency on metformin develops slowly (typically 4+ years of use) and produces fatigue, cognitive symptoms, and peripheral neuropathy — symptoms commonly misattributed to diabetes itself. Metformin also modestly affects folate and CoQ10, and magnesium supplementation may enhance metformin''s metabolic effects. This protocol is for adults ACTIVELY on metformin (any indication: T2DM, prediabetes, PCOS, or off-label use). CRITICAL: this protocol does NOT replace metformin. The supplements address downstream nutritional effects. The American Diabetes Association recommends periodic B12 testing for long-term metformin users — particularly in adults over 50, vegetarians/vegans, and those with neurological symptoms. Don''t skip B12 monitoring.
PPI / Acid Blocker Companion
medication· 3 shared ingredients
Proton pump inhibitors (omeprazole/Prilosec, esomeprazole/Nexium, pantoprazole/Protonix, lansoprazole/Prevacid) are among the most-prescribed medications globally — and frequently used much longer than recommended. Long-term PPI use (more than 6-12 months) is associated with multiple documented nutrient malabsorption issues because stomach acid is REQUIRED for absorbing B12, calcium, iron, magnesium, and zinc. Reduced stomach acid also alters the gut microbiome, increases risk of C. difficile and pneumonia infections, and is associated (though not necessarily causal) with osteoporotic fractures, dementia, and kidney issues in long-term users. This protocol is for adults ACTIVELY on long-term PPIs or H2 blockers (famotidine/Pepcid, ranitidine — now removed for NDMA contamination). The supplements address the documented nutrient gaps that develop with chronic acid suppression. CRITICAL secondary message: many PPI users could safely wean off if working with their doctor. PPIs are appropriate for confirmed Barrett''s esophagus, erosive esophagitis, peptic ulcer disease — but are commonly prescribed long-term for milder reflux that would respond to lifestyle changes and intermittent H2 blocker use. Talk to your prescriber about whether you''re actually a long-term PPI candidate or could try weaning. See Acid Reflux / Heartburn protocol for non-pharmaceutical alternatives.
Long COVID / ME/CFS Recovery
chronic illness· 3 shared ingredients
Long COVID (Post-Acute Sequelae of SARS-CoV-2, PASC) affects an estimated 65 million people globally — and overlaps substantially with myalgic encephalomyelitis / chronic fatigue syndrome (ME/CFS), a condition that affected millions before COVID and remains under-diagnosed. Both share core features: profound fatigue not relieved by rest, post-exertional malaise (PEM — symptoms worsening 12-48 hours after physical, cognitive, or emotional exertion), cognitive dysfunction ("brain fog"), sleep disruption, and orthostatic intolerance. The mechanism research is rapidly evolving — current hypotheses include viral persistence, mitochondrial dysfunction, autonomic nervous system dysregulation, micro-clotting, and neuroinflammation. CRITICAL: This protocol is ADJUNCTIVE. It does NOT replace proper medical care. Long COVID and ME/CFS are real diseases that benefit from specialist evaluation (post-COVID clinics where available, ME/CFS-experienced clinicians, sometimes immunology or neurology). Some patients benefit from prescription interventions (low-dose naltrexone, paxlovid courses, anticoagulation in select cases). Supplements address the metabolic and oxidative-stress dimensions — they''re not the answer. The single most important non-supplement intervention is PACING — staying within your energy envelope to prevent post-exertional malaise. Traditional graded exercise therapy (GET) can WORSEN ME/CFS symptoms; modern guidance emphasizes pacing over progressive exertion.
Endurance Athlete Stack
recovery· 3 shared ingredients
Endurance athletes (runners, cyclists, swimmers, triathletes, rowers) have specific nutritional demands that differ from strength athletes: massive sweat losses (electrolytes), iron depletion risk (especially in female endurance athletes — "footstrike hemolysis" plus menstrual losses), heavy oxidative stress, B12 needs from extensive Zone 2 work, and mitochondrial demands. The supplement category here has clear evidence: beetroot (nitrates) for oxygen efficiency and performance in events 5-30 minutes long, electrolytes for sweat replacement (mandatory in sessions over 60 minutes), iron when ferritin is confirmed low, B12 for energy metabolism, and CoQ10 for mitochondrial support. This is for serious endurance training (5+ hours/week aerobic work), not casual runners. Pair with proper carb fueling, hydration strategy, and sleep — supplements complement, never replace, the training-and-recovery foundation.
