Several recent studies have found that vitamin D supplements may help protect against COVID-19.
For example, in a study at Albert Einstein College of Medicine in New York, researchers found that patients with low vitamin D levels who are hospitalized for COVID-19 may have a lower risk of dying or requiring mechanical ventilation if they receive vitamin D supplementation of at least 1,000 units weekly.
They tested 124 adult patients with low vitamin D that was measured up to 90 days before their admission for COVID-19.
The team found that patients who were supplemented were less likely to be mechanically ventilated or to die following admission.
The researchers say it is clear that patients with low vitamin D should receive supplementation not only for bone health but also for stronger protection against severe COVID-19.
In another study from the University of Chicago, researchers found that when it comes to COVID-19, having vitamin D levels above those traditionally considered sufficient may lower the risk of infection.
They looked at data from over 3,000 patients at U Chicago Medicine who had had their vitamin D levels tested within 14 days before a COVID-19 test.
The team found that people who had lower levels of vitamin D in the body had a 2.64 times higher risk of testing positive for COVID-19 than people with higher levels of vitamin D.
This research is an expansion of an earlier study showing that a vitamin D deficiency (less than 20 ng/ml) may raise the risk of testing positive for COVID-19.
The team suggests that having vitamin D levels above those normally considered sufficient is linked to a decreased risk of testing positive for COVID-19.
In addition, a separate study recently found that over 80% of patients diagnosed with COVID-19 were vitamin D deficient.
In a study from the University of Bristol, scientists found why vitamin D may help combat COVID-19.
They found that vitamin D supplements (and possibly vitamins K and A ) could bind to the viral spike protein and so may reduce SARS-CoV-2 infectivity.
The research of vitamin D and COVID-19 continues, and other studies have found controversial results about vitamin D and severe COVID-19. More work is needed in the future to clarify the association.
Which vitamin D is the best for your health?
There are several types of vitamin D. The recommended form of vitamin D is vitamin D3 or cholecalciferol. This is the natural form of vitamin D that your body can make from sunlight.
A recent study suggested that that vitamin D2 (ergocalciferol) works as well as vitamin D3.
Vitamin D2 and D3 differ depending on their food sources. Vitamin D3 is only found in animal-sourced foods, whereas D2 mainly comes from plant sources and fortified foods.
Scientists have found that vitamin D2 and D3 are not equal when it comes to raising your vitamin D status.
While both are effectively absorbed into the bloodstream, the liver metabolizes them differently. Vitamin D3 Is more effective at improving your vitamin D status.
