Low Vitamin D Levels May Reduce Lung Function.

Specific Vitamins Are Beneficial for Helping Support Respiratory Health, According To New Research. Australian researchers have presented evidence of a causal relationship between vitamin D status and lung function, in a laboratory-controlled study. Recent studies have linked poor vitamin D status to reduced lung function and disease, however until now causal data to confirm such a relationship has been lacking. The new study, published in the American Journal of Respiratory and Critical Care Medicine claims to offer the first evidence of linking low levels of vitamin D to a reduction in lung function and altered lung structure. "For the first time, we have demonstrated a direct role for vitamin D in causing decreased lung function... confirming the assertion by epidemiological studies that there is a relationship between vitamin D deficiency and lung function," explained researchers from the Telethon Institute for Child Health Research in Australia. "The differences we observed in lung volume and lung mechanics, which were substantial and physiologically relevant, raise serious concerns regarding the increased prevalence of vitamin D deficiency in communities around the world," they said.
