Micronutrients & recovery
Higher serum 25-hydroxyvitamin D (25(OH)D) concentrations are linearly associated with a lower risk of respiratory infections and improved lung function (FEV1 and FVC) in British adults.
Maintain adequate vitamin D levels, particularly during winter months, as higher levels are associated with fewer respiratory infections and better lung function. This is an observational finding, so while it supports general health guidelines for vitamin D, it does not prove that supplementation alone prevents all infections.
Each 10 nmol/l increase in 25(OH)D was associated with a 7 % lower risk of infection... For FEV1 and FVC, each 10 nmol/l increase in 25(OH)D was associated with 8... ml and 13... ml higher volume, respectively
Why this rating
Observational cross-sectional study with large sample size but inherent limitations of causality and potential residual confounding.
