Researchers at the University of Alberta have identified an amino acid called taurine that may play a key role in predicting and treating long COVID. The study, published on October 25, 2023 in the journal Cell Systems, found that patients with low levels of taurine in their blood were more likely to develop long COVID, and that supplementing with taurine improved symptoms in some patients.
Taurine is a semi-essential amino acid, meaning that the body can produce it but not enough to meet all of its needs. Taurine is found in meat, fish, and dairy products, and it is also available as a supplement.
The researchers studied 55 patients who had been hospitalized with COVID-19. They found that patients who developed long COVID had lower levels of taurine in their blood than those who did not. The researchers then developed a predictive model using blood samples from the patients. The model was able to predict with 83% accuracy which patients would develop long COVID.
The researchers also conducted a small clinical trial in patients with long COVID. They found that patients who supplemented with taurine for 12 weeks had a significant improvement in their symptoms, including fatigue, shortness of breath, and muscle pain.
The researchers believe that taurine plays a role in protecting the body from the damaging effects of COVID-19. Taurine has antioxidant and anti-inflammatory properties, and it is also important for mitochondrial function. Mitochondria are the organelles in cells that produce energy.
The researchers are now planning a larger clinical trial to confirm the benefits of taurine supplementation for long COVID. In the meantime, they advise patients to talk to their doctor before taking taurine supplements.
Implications for Patients
The findings of this study are promising for patients with long COVID. Taurine is a relatively safe and inexpensive supplement, and it may be effective in improving symptoms and preventing the development of long COVID in the first place.
However, it is important to note that the study was small and more research is needed to confirm the benefits of taurine supplementation for long COVID. Patients should talk to their doctor before taking taurine supplements, especially if they have any underlying health conditions.
Future Research
The researchers at the University of Alberta are planning a larger clinical trial to confirm the benefits of taurine supplementation for long COVID. They are also interested in investigating the mechanisms by which taurine protects the body from the damaging effects of COVID-19.
Other researchers are also investigating potential treatments for long COVID. Some promising areas of research include:
- Anti-inflammatory drugs
- Antiviral drugs
- Immunomodulatory drugs
- Rehabilitation programs
More research is needed to develop safe and effective treatments for long COVID. However, the findings of this study are a promising step forward.
