Vitamin D Linked to Lower Respiratory Infection Hospitalisations, UK Study Finds
A UK study analyzing about 36,000 adults found that severe vitamin D deficiency (<15 nmol/L) was linked to a 33% higher likelihood of hospital admission for respiratory infections (including flu, pneumonia and bronchitis) compared with those with adequate levels (>75 nmol/L). Moreover, for every 10 nmol/L increase in vitamin D, respiratory infection hospitalisations fell by around 4%. The NHS already recommends a daily 10 microgram vitamin D supplement during autumn and winter, and the vitamin is found in foods like oily fish, red meat, egg yolks and fortified cereals. Published in the American Journal of Clinical Nutrition, the study underscores vitamin D’s potential antiviral benefits and notes older adults and ethnic minority groups are at higher risk of deficiency.
