What is Long COVID, and how can Low-Dose Naltrexone help with it?
Long COVID is a range of symptoms that persist for weeks/months after the initial COVID-19 infection has passed.
LDN helps ease symptoms like brain fog and tiredness by reducing inflammation [1]
A study from Stanford found that 54.2% of 59 Long COVID patients using LDN experienced an improvement in symptoms like fatigue, post-exertional malaise, unrefreshing sleep, and abnormal sleep patterns [2]
A study of 108 patients taking amitriptyline, low-dose naltrexone, and physical therapy found that those taking LDN had a 5 times higher likelihood of improvement for both fatigue and pain [3]
