This study tests whether PNMR (a supplement product) can safely reduce symptoms of long COVID—the lingering fatigue, brain fog, and other problems that some people experience months after COVID infection. You'll take the study product, follow diet and exercise guidelines, and complete questionnaires and a walking test.
This trial tests a non-invasive brain stimulation method called Transcranial Pulse Stimulation (TPS) to see if it can help people with lingering post-COVID symptoms like fatigue and brain fog. If you've had COVID-19 and still have symptoms for at least 12 months, this study might be an option for you.
This trial tests whether immune-modulating treatments can help people with long covid, especially those with ongoing heart, cough, or fatigue symptoms. It aims to see if calming the immune system reduces symptoms and improves daily life.
This trial tests a medicine called Sonlicromanol to see if it helps people with lingering symptoms after a mild case of COVID-19. It is for people who have post-exertional malaise (feeling very tired or worse after activity) and a moderate level of disability.
This study tests whether improving diet quality can reduce fatigue and symptoms in people with long-COVID (post-acute COVID-19 syndrome). It may help if your diet quality is currently low and your fatigue is moderate to severe.
