SARS-CoV-2, the virus that caused the COVID-19 global pandemic, has caused millions of cases and deaths worldwide. Of those who recovered after hospitalization, at least 60% developed long COVID, a condition in which symptoms remain for weeks after exposure. Since COVID has caused a significant toll on some immune systems, there has been increased interest in learning more about the effects Vitamin D and B-12 have on COVID.
Vitamin D is an essential vitamin known for creating healthy muscles, teeth, and bones. It also controls how much calcium is absorbed in the body and helps with mood stability and immune function. Studies show patients with a Vitamin D deficiency have a weaker immune system, and increase their risk of severe or critical case of COVID by more than a factor of 12. Patients with insufficient Vitamin D also have nearly 10 times the mortality rate of those with adequate Vitamin D. A Vitamin D deficiency can be caused by obesity, sedentary indoor lifestyles, and sun avoidance.
Vitamin B-12 is an essential nutrient that’s involved in regulating the immune system and antiviral activity. Not normally produced by the body, it occurs naturally in foods such as meat, poultry, fish, eggs, and dairy. Vitamin B-12 deficiency is common in developing countries and in people with restrictive diets. Studies have shown that if you’re vitamin B-12 deficient, your body can’t slow down COVID’s viral replication.
