Vitamins A and D linked to improved lung function in asthma patients A study by US researchers published in Thorax found that higher levels of vitamins A and D are linked to improved lung function in children and adults with asthma. Higher vitamin D levels were also associated with less epigenetic ageing in adults, suggesting a potential role in slowing biological ageing. Vitamins A and D linked to improved lung function in asthma patients - A study by US researchers suggests that higher levels of vitamins /topic/vitamins A and D could boost lung function in children and adults with asthma /topic/asthma . - The research, published in the journal Thorax, analysed data from 1,165 children and 1,041 adults with asthma, measuring their vitamin levels and lung capacity. - The findings indicated that both children and adults with asthma who had higher vitamin A levels exhibited better lung function. - Among adults with asthma, higher vitamin D levels at least 30 ng/ml were associated with improved lung function and less evidence of epigenetic ageing, suggesting a potential role in slowing biological ageing. - Experts have cautioned that while these findings open new avenues for investigation, further studies are required to clarify the causal relationship between vitamin D, biological ageing, and lung health.
