About this protocol

Persistent fatigue lasting 6+ months — distinct from temporary tiredness — affects roughly 25% of primary care visits and is one of the most under-diagnosed symptom clusters in medicine. The differential diagnosis is wide: anemia, hypothyroidism, sleep apnea, depression, chronic infections, mitochondrial dysfunction, post-viral syndromes (ME/CFS, Long COVID), early autoimmune disease. This protocol is for ADJUNCTIVE support after appropriate medical workup — supplements complement proper diagnostic workup and treatment of underlying causes. CoQ10 and NAD+ precursors (NMN or NR) target mitochondrial function (a documented finding in many chronic fatigue states); iron and B12 correct common reversible deficiencies; magnesium supports the multiple systems affected by chronic fatigue. If you have persistent unexplained fatigue, please see a doctor BEFORE relying on supplementation alone. The labs that should be done first: CBC, ferritin, TSH/free T4/T3, vitamin B12, vitamin D, fasting glucose, HbA1c, lipid panel, hsCRP, ESR, and consideration of further workup based on symptoms.

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.

5 nutrients

Start here

Strongest evidence — the foundation of the stack.

CoQ10 (Ubiquinol)

200-300 mg daily, with a fat-containing meal
morningwith food

CoQ10 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 breakfast
morningwith food

NAD+ 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 tolerated
morningempty stomach

Iron 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 breakfast
morningwith food

Low 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 bed
before bedempty stomach

Magnesium 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

Do not take with: Anticoagulants (CoQ10 may modestly reduce warfarin effect — monitor INR). Anti-seizure medications (B12 deficiency can mask folate deficiency in seizure-prone patients). Tetracycline/quinolone antibiotics with iron (space 2 hours). Thyroid medication (iron and calcium reduce absorption — space 4 hours). Lithium (magnesium interactions). Methotrexate (folate antagonist — don't combine with high-dose B-complex without oncology oversight).
Do not take if: You are pregnant or breastfeeding (consult provider; NAD+ precursors not well-studied in pregnancy). You have hemochromatosis (skip iron entirely). You have severe kidney disease. You take prescription medications affecting metabolism, blood, or thyroid. Critical: persistent unexplained fatigue warrants medical workup — don't default to supplementation without ruling out hypothyroidism, anemia, sleep apnea, depression, diabetes, autoimmune disease, chronic infections, or post-viral syndromes (ME/CFS, Long COVID).

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.
