- 01Vitamin D3Moderate72% match
Vitamin D supports immune regulation and muscle function, and low levels are common and may hinder recovery in post-viral states.
SuggestedVitamin D3 softgel, 1000 to 2000 IU daily, dosed to lab levels - 02Coenzyme Q10Limited68% match
CoQ10 supports mitochondrial ATP production, and mitochondrial dysfunction is one proposed driver of persistent fatigue after viral illness.
SuggestedUbiquinol softgel, 100 to 200 mg daily with food - 03NACLimited64% match
NAC is a precursor to the antioxidant glutathione and may theoretically counter the oxidative stress and inflammation implicated in long COVID.
SuggestedN-Acetyl Cysteine capsule, 600 to 1200 mg daily - 04Magnesium GlycinateLimited60% match
Magnesium supports energy metabolism, nerve function, and sleep, all of which can be disrupted in post-viral fatigue, with benefit most likely when intake is low.
SuggestedMagnesium glycinate capsule providing 200 to 300 mg elemental magnesium in the evening - 05Fish OilLimited57% match
Omega-3 fatty acids in fish oil have anti-inflammatory effects that may help resolve the lingering inflammation proposed in post-viral symptoms.
SuggestedTriglyceride-form fish oil, 1 to 2 g combined EPA and DHA daily with food - 06Acetyl-L-CarnitineLimited55% match
Acetyl-L-Carnitine aids mitochondrial fatty acid transport and may theoretically support energy and mental clarity during post-viral fatigue.
SuggestedAcetyl-L-Carnitine capsule, 500 to 1000 mg daily
