Cod Liver Oil Can't Prevent Covid-19
Like vitamin D supplements, research on cod liver oil shows that the material isn't suitable for the Covid cure or treatment. The result of this research was shared by The BMJ, which showed that cod liver oil also contained a small amount of vitamin D, vitamin A, and omega-3 fatty acids.
Unlike the vitamin D supplement test, more people participated in this cod liver oil research. About 35,000 adults from Norway volunteered to participate in the test.
To participate in the test, those who volunteered had to take either 5 ml of cod liver oil or 5 ml of placebo daily for a period of 6 months. The medical professionals who conducted the test said that the participants had good vitamin D levels before starting the study.
This particular cod liver oil study occurred from November 2020 to June 2021 and yielded quite disappointing results.
The result showed that despite the combination of cod liver oil and vitamins D and A, the cod liver oil had no major effect on Covid-19 and respiratory tract infections.
