- About each six in 100 individuals who have COVID-19 go on to develop post-COVID-19 situation, dubbed ‘lengthy COVID.’
- There may be at the moment no treatment for lengthy COVID and anybody who’s contaminated with the coronavirus that causes COVID-19 can develop it.
- Previous research present that sure way of life decisions, reminiscent of following a nutritious diet, might assist scale back an individual’s lengthy COVID danger.
- A brand new research discovered that whereas vitamin D dietary supplements might not scale back the severity of COVID-19, they might assist scale back an individual’s danger of growing lengthy COVID.
Anybody who’s contaminated with the coronavirus that causes COVID-19 can develop lengthy COVID. Nonetheless, older adults, these with extreme COVID-19, and folks with underlying well being circumstances are typically
Now, a brand new research printed in The Journal of Nutrition has discovered that, whereas vitamin D dietary supplements might not scale back the severity of a COVID-19 an infection, they might assist scale back an individual’s danger of growing lengthy COVID.
For this research, researchers recruited greater than 1,700 adults in america and Mongolia who had lately examined optimistic for COVID-19, in addition to 277 members of their family who got here involved with the contaminated particular person.
Members had been randomly chosen to obtain both a day by day vitamin D3 complement or placebo for 4 weeks. The common time between a participant’s optimistic COVID-19 check and begin of the vitamin D3 complement or placebo was 3 days.
“Lengthy COVID continues to influence the lives and high quality of lifetime of thousands and thousands of individuals worldwide,” JoAnn Manson, MD, DrPH, chief of the Division of Preventive Drugs at Mass Basic Brigham, Michael and Lee Bell Professor of Ladies’s Well being at Harvard Medical College, and senior writer of this research, instructed Medical Information In the present day.
“Analysis so far has supplied few solutions on causes, prevention, or therapy of lengthy COVID,” Manson famous.
On the research’s conclusion, scientists discovered that research members who saved to their vitamin D routine demonstrated a sign that they had been at a decrease danger of growing lengthy COVID signs at 8 weeks, when in comparison with these taking the placebo.
Moreover, of these within the vitamin D group, 21% reported at the very least one persistent symptom, whereas 25% did within the placebo group.
“Vitamin D is understood to have favorable results on immune well being and to tamp down irritation, which is believed to be a key driver of lengthy COVID,” Manson defined. “It was shocking to us to see a sign for profit towards lengthy COVID, on condition that the therapy interval lasted solely 4 weeks.”
“Our VIVID trial confirmed suggestive advantages of vitamin D for prevention of lengthy COVID, which deserves additional research,” she added. “A bigger randomized trial is critical to supply better statistical certainty.”
The researchers additionally famous that there was no distinction between the vitamin D and placebo teams over a 4-week interval when taking a look at charge of hospitalizations, clinic visits, ER journeys, or deaths, and no vital distinction was discovered when it comes to COVID symptom severity between the 2 teams.
Moreover, taking high-dose vitamin D didn’t decrease the speed at which family members contracted COVID-19.
“A key takeaway is that vitamin D supplementation appears to be like promising for lowering the danger of growing lengthy COVID, however doesn’t seem to have an effect on the severity of the acute an infection,” Manson stated.
“That is most likely as a result of vitamin D tamps down irritation and prevents the longer-term problems of lengthy COVID, however not signs which can be already underway,” she added.
“These findings are according to our earlier findings in VITAL that vitamin D lowers biomarkers of irritation — reminiscent of CRP (c-reactive protein) — and reduces the long run danger of autoimmune illness however doesn’t have an effect on signs which can be already ongoing,” she continued.
“A suggestion could be to extend background consumption of vitamin D through the winter or different durations when COVID and different viral infections change into extra prevalent. This will additionally scale back the danger of growing lengthy COVID. We’re planning an extra randomized trial to check high-dose vitamin D for treating the signs of lengthy COVID.”

MNT had the chance to talk with Fady Youssef, MD, a board-certified pulmonologist, internist and significant care specialist at MemorialCare Lengthy Seaside Medical Middle in Lengthy Seaside, CA, about this research.
Youssef, who was not concerned within the the analysis, commented that his first response to the analysis outcomes was that the story of vitamin D stays considerably unresolved.
“We’ve recognized for years that vitamin D appears to affect quite a lot of well being outcomes past bone health, however we nonetheless don’t totally perceive the mechanisms or the circumstances during which it supplies profit,” he instructed us.
Hypothesizing on how vitamin D would possibly be capable of assist scale back lengthy COVID danger, Youssef famous that vitamin D performs a job in regulating immune responses and irritation.
“One risk is that satisfactory vitamin D helps the immune system resolve an infection in a extra balanced approach, probably lowering the lingering irritation or immune dysregulation that many researchers imagine contributes to lengthy COVID,” he instructed us.
“It’s additionally attainable that vitamin D impacts metabolic and endothelial pathways that affect restoration after viral sickness,” Youssef continued.
“Lengthy COVID can considerably have an effect on high quality of life for months and even years, and we nonetheless lack clear diagnostic markers and a full understanding of the underlying biology,” he added. “Understanding what lengthy COVID is and what causes it should inform future medical care and epidemic preparedness.”
