- A review of 15 years of research data found that taking vitamin D supplements during pregnancy may reduce the risk of asthma and wheezing in children.
- Given the vitamin D deficiency of many pregnant women who do not take supplements, experts say this study supports the idea of increasing daily vitamin D3 intake from the time of pregnancy.
- This new study contrasts with previous studies in which researchers concluded that vitamin D supplementation during pregnancy is not very effective.
New research published in Journal of Allergy and Clinical Immunology Strengthens the association between prenatal vitamin D levels and risk of wheezing and asthma in children.
This analysis includes 15 years of data on the reduction of prenatal asthma with vitamin D (
The study’s lead author, Scott Weiss, associate director of the Channing Network Department of Medicine at Brigham and Women’s Hospital and a professor at Harvard Medical School in Massachusetts, explained the key findings: Today’s medical news “Administering 4,400 IU of vitamin D3 per day to pregnant women reduced asthma in their offspring compared to women who received 400 IU per day.”
“This is important because most pregnant women have insufficient intakes of vitamin D3,” he said.
“When considered in conjunction with other vitamin D pregnancy tests, we recommend that all pregnant women take 4,000 to 6,000 IU of vitamin D3 per day throughout pregnancy,” Weiss added.
Based on this finding, experts suggest that pregnant women should consider taking at least 4,400 IU of vitamin D3 daily starting in early pregnancy.
Vitamin D, which can be obtained through sun exposure, diet, and supplements, is primarily known to be important for bone health, but it can also help manage autoimmune and other diseases.
A new review has established a link between vitamin D deficiency and increased risk of asthma and wheezing in children.
The relationship between vitamin D levels during pregnancy and childhood asthma is a subject of debate.
Several
However, I get the following result:
In this latest study, scientists noted that:
Researchers noted that in the original VDAART study, pregnant women with a family history of allergies or asthma were recruited between 10 and 18 weeks of pregnancy.
Half of these women received an additional 4,400 IU of vitamin D on top of the 400 IU included in the prenatal vitamin, and the other half received a placebo in addition to the prenatal vitamin.
of
By the time the children reached 6 years of age, the findings became even less significant.
However, when we stratified the results based on vitamin D levels in the control group, both sets of analyzes gained significance.
By adjusting initial vitamin D levels, the researchers observed the expected effect seen in observational studies: a 50% reduction in the incidence of asthma and wheezing.
Based on insights from the VDAART study, researchers in the new study recommend that future clinical trials should start as early in pregnancy as possible, recommend 6,000 IU of vitamin D supplementation, and involve a significant number of women in the study. It emphasizes the importance of color.
The researchers said such studies could improve our understanding of the potential effects of vitamin D on pregnancy outcomes and the development of asthma in childhood.
Dr. Raj Dasgupta, chief medical advisor at Sleep Advisor, who was not involved in the study, said: Today’s medical news The research results are interesting.
These results suggest a potential association between increased vitamin D supplementation in pregnant women and a reduced risk of childhood asthma in the fetus.

Dasgupta points out that studies have shown how high doses of vitamin D during pregnancy are associated with a lower risk of asthma in children aged 3 and 6, along with improved allergies and lung function. did.
However, Professor Dasgupta stressed the need for further research to validate these findings and assess safety and effectiveness for all pregnant women, taking into account individual health circumstances.
Pediatric nutritionist Lauren Mahesri, RDN, LD, who was also not involved in the study, said: Today’s medical news That “this” [study] Shedding new light on an important topic in maternal and child nutrition. ”
“Vitamin D deficiency in women and childhood asthma are both very common, so the finding that vitamin D status influences the incidence of asthma is very important,” she said.
“One of the recent
One of the biggest implications from this study is that higher vitamin D supplementation, especially at doses of 4,400 IU/day, may help reduce the risk of asthma (prenatal multivitamins containing standard vitamin D). 400 IU/day). descendants.

“This should encourage dietitians and health care providers to reassess their pregnant patients’ vitamin D status throughout pregnancy and provide appropriate supplements,” Mahesri said.
“This study also highlights the importance of maternal nutrition during pregnancy and its impact on the child’s long-term health status,” she said.
“This highlights the importance of evidence-based recommendations regarding prenatal nutrition and supplementation,” Mahesri explained.
