About this protocol

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.

Where to start

See a clinician first. Long COVID clinics, ME/CFS-experienced providers, and integrative medicine doctors may be more thorough than general practitioners. Get baseline workup: CBC, ferritin, vitamin D, B12 + MMA, comprehensive metabolic panel, thyroid panel, hsCRP, fasting glucose, lipid panel, plus consideration of cortisol, sex hormones, autonomic testing (tilt-table for POTS), and chronic infection screening.

Learn to pace BEFORE adding supplements. Pacing means staying within your energy envelope and proactively resting before exertion causes a crash. Heart-rate monitoring (Whoop, Garmin, Apple Watch) is hugely helpful — most ME/CFS patients have an anaerobic threshold around 100-110 bpm, and exceeding it triggers post-exertional malaise. Supplements work; pacing makes them work.

Start with CoQ10 (ubiquinol) at 200-300 mg daily. The most-evidenced supplement for ME/CFS. Castro-Marrero 2015 trial in CFS showed CoQ10 + NADH improved fatigue scores and biochemical markers over 8 weeks.

Add a NAD+ precursor (NMN or NR). Mitochondrial dysfunction in Long COVID and ME/CFS is documented; NAD+ supports energy production. Castro-Marrero''s follow-up work with NADH supports the broader pathway.

Add L-carnitine at 2-3 g daily. Carnitine shuttles fatty acids into mitochondria for oxidation. Trials in ME/CFS show modest benefit.

Add magnesium glycinate at 300-400 mg before bed. Supports sleep (commonly disrupted), anxiety, and the muscle-cramping that''s common in this population.

Add electrolytes (sodium + potassium + magnesium) if you have POTS-like symptoms (lightheadedness on standing, fatigue worsening with upright posture, tachycardia on standing). High-sodium intake (5-10 g salt/day) is a first-line POTS intervention.

Expect 12+ weeks before judging. Chronic illness recovery is slow. Track symptom severity weekly with structured scales (DePaul Symptom Questionnaire for ME/CFS) — perception of improvement is unreliable; data is informative.

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 — a documented dysfunction in ME/CFS and emerging in Long COVID research. The Castro-Marrero 2015 trial showed CoQ10 + NADH improved fatigue scores and biochemical markers in CFS over 8 weeks. Fukuda 2016 trial supports cognitive and autonomic improvements. Ubiquinol form has better bioavailability than ubiquinone, especially in adults over 40.[1, 2, 3]

NAD+ Precursor (NR or NMN)

250-500 mg daily, with breakfast
morningwith food

NAD+ is essential for mitochondrial energy production and is depleted in chronic fatigue states. NR and NMN reliably raise blood NAD+. The evidence base 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.

L-Carnitine (Acetyl-L-Carnitine or L-Carnitine L-Tartrate)

2-3 g daily, divided AM/midday
morningempty stomach

L-carnitine shuttles long-chain fatty acids into mitochondria for oxidation. Trials in ME/CFS show modest improvements in fatigue scores. Plioplys 1997 trial supports use; acetyl-L-carnitine may have additional cognitive benefits.[7, 8, 9]

Magnesium Glycinate

300-400 mg elemental, before bed
before bedempty stomach

Magnesium supports the multiple systems affected in chronic fatigue: ATP production, muscle function, sleep architecture, nervous system regulation. Cox 1991 Lancet trial showed reduced CFS symptoms with magnesium supplementation in red-blood-cell magnesium-deficient adults. Most chronic illness patients under-consume magnesium.[10, 11]

Experimental

Emerging evidence — try last, only if curious.

Electrolytes (Sodium + Potassium + Magnesium) — for POTS symptoms

Sodium 3-5 g additional daily for POTS-like symptoms; standard electrolyte blend
morningempty stomach

POTS (Postural Orthostatic Tachycardia Syndrome) is common in Long COVID and ME/CFS. Higher-than-standard sodium intake (5-10 g salt/day) is a first-line POTS intervention recommended by autonomic specialists. Combined with adequate fluid intake and compression garments, it can dramatically reduce orthostatic symptoms.[12, 13]

Warnings

Do not take with: Anticoagulants (CoQ10 may modestly reduce warfarin effect — monitor INR). Antihypertensive medications with high-sodium intake (if you have hypertension AND POTS, coordinate with cardiologist). Sedatives and CNS depressants. Stimulants — caution with traditional pre-workouts and high-caffeine products that can trigger post-exertional malaise.
Do not take if: You have not had a proper medical workup (see a doctor first — Long COVID and ME/CFS warrant evaluation). You have hypertension AND consider increased sodium for POTS-like symptoms (coordinate with cardiologist; competing interests). You are pregnant or breastfeeding (NAD+ precursors not well-studied; coordinate with OB and Long COVID clinic). You take warfarin. CRITICAL: traditional Graded Exercise Therapy (GET) is controversial in ME/CFS — modern guidance from many specialists emphasizes pacing over progressive exercise. Discuss exercise approaches with a knowledgeable clinician.

Lifestyle improvements

Pace, don''t push

The most-evidenced intervention for ME/CFS and Long COVID is PACING — staying within your energy envelope. Post-exertional malaise (PEM) is the symptom of doing too much; symptoms worsen 12-48 hours after exertion. Traditional Graded Exercise Therapy (GET) can WORSEN ME/CFS in many patients. Use heart rate monitoring (anaerobic threshold typically 100-110 bpm) to stay below your crash point.

See a Long COVID or ME/CFS specialist

Many primary care doctors aren''t familiar with these conditions. Post-COVID clinics, integrative medicine, autonomic specialists, and ME/CFS-experienced providers offer more thorough evaluation. Treatment is multi-modal.

Get the right labs

Beyond standard CBC and ferritin: thyroid (TSH, free T4, free T3, antibodies), cortisol (4-point saliva), vitamin D, B12 with MMA, hsCRP, comprehensive metabolic panel, fasting glucose + insulin, tilt-table testing for POTS, chronic infection screening (EBV, CMV, sometimes Lyme/coinfections depending on history).

Sleep is non-negotiable

Unrefreshing sleep is a core feature of ME/CFS. The Better Sleep protocol stacks here. CPAP if sleep apnea is identified (commonly missed). Treat sleep aggressively.

Address dysautonomia / POTS

If you have orthostatic symptoms (lightheadedness standing, fatigue worsening upright, tachycardia on standing 30+ bpm increase), workup for POTS. Treatment includes: increased sodium (5-10 g/day) and fluids, compression garments, sometimes prescription medications (ivabradine, midodrine, fludrocortisone).

Mental health support

Chronic illness amplifies depression and anxiety. This is not "all in your head" — it''s a real consequence of being chronically ill. Therapy (especially with chronic illness expertise) can help. Avoid practitioners who dismiss your symptoms as psychogenic.

Anti-inflammatory dietary pattern

Mediterranean dietary pattern, reduced ultra-processed foods, reduced alcohol. Some patients identify specific food triggers (gluten, dairy) — structured elimination trials are reasonable.

Limit alcohol entirely

Alcohol triggers PEM in many patients and disrupts sleep architecture. Many ME/CFS and Long COVID patients find total alcohol elimination significantly improves symptoms.

Consider low-dose naltrexone

LDN (low-dose naltrexone, 1.5-4.5 mg) has growing trial evidence in ME/CFS and Long COVID. Prescription required. Discuss with your Long COVID clinic or integrative medicine provider.

Track symptoms structurally

DePaul Symptom Questionnaire (free, online) is a validated ME/CFS assessment. Weekly or biweekly tracking reveals trends supplements alone don''t. Subjective perception is unreliable; data is informative.

Connect with patient communities

Long COVID and ME/CFS communities (Body Politic, MEAction, Solve ME/CFS Initiative) offer peer support, advocacy, and resources. Many medical advances come from patient-led research.

Don''t accept dismissal

Both Long COVID and ME/CFS have been historically dismissed as psychogenic. They aren''t. If a clinician dismisses your symptoms without proper workup, find a different clinician. Patient advocacy organizations have provider lists.

Patience

Recovery from chronic illness is slow — typically months to years. Avoid the trap of constantly switching supplements every 2-3 weeks. Pick a protocol, give it 12-16 weeks, track structured outcomes, then adjust.
