Reduce Sickness with Vitamin D

In this study, they took 695 children with 14% of them experiencing childhood croup before the age of three. The risk of croup was significantly lower in the group receiving high dose vitamin D and fish oil than the group receiving standard dose vitamin D and olive oil supplementation. The findings suggest a reduced risk of croup in early childhood with fish oil and high-dose vitamin D supplementation during pregnancy.

“Croup is one of the most common acute childhood respiratory disorders. It is characterized by inspiratory stridor, hoarse voice, and barky cough. Croup is often caused by parainfluenza viruses leading to inflammation of the larynx and trachea. It mainly affects children aged 6 months to 3 years.”

“The risk of croup during the first 3 years of life was reduced by 38% and 40% by prenatal supplementation with n-3 LCPUFA(fish oil) and high-dose vitamin D, respectively, during the double-blinded period of a DB-RCT.”

This research was done because they wanted to explore preventative methods for croup, which is one of the most common acute childhood respiratory disorders. Croup can lead to inflammation of the larynx and trachea, affecting children aged 6 months to 3 years. The research showed to importance of a proper fish oil and high dose vitamin D supplement. When it comes to fighting disease and sickness, lifestyle and proper nutrition will always be the best route to go. That is why every Doctor in our East Dallas Clinic will always stress Eat well, Move well, and Think well, because we know that it is what it takes to be healthy and stay healthy.


The study was completed in the Danish population-based single-center Copenhagen Prospective Studies on Asthma in Childhood 2010 mother–child cohort, which included 736 pregnant women. Croup was diagnosed by physicians’ clinical examinations and medical record checks. Potential mediating mechanisms were investigated using blood metabolomics, airway cytokines, and airway microbiome.


Of 695 children, 97 had croup before age 3 years (14%). The risk of croup was reduced in the n-3 LCPUFA (ncases / ntotal = 38/346; 11%) versus olive oil group (59 of 349 children; 17%) (hazard ratio = 0.62; 95% CI, 0.41-0.93; P = .02) and in the high-dose vitamin D group (32 of 295 children; 11%) versus the standard-dose group (51 of 286 children; 18%) (hazard ratio = 0.60; 95% CI, 0.38-0.93; P = .02). There was no evidence of interaction or additive effects between the supplements (Pinteraction = .56). Furthermore, the results did not change when they were adjusted for each other, persistent wheeze, and lower respiratory tract infection.
