Vitamin D supplementation reduces need for respiratory support, study suggests


Research workers from Bostons Massachusetts General Hospital and Harvard Medical School have found that insufficient vitamin D supplementation among surgical intensive care patients can raise the amount of time needed on respiratory support.(1)

The study, titled Plasma 25-Hydroxyvitamin D Degrees at Initiation of Attention and Duration of Mechanical Ventilation in Critically Ill Surgical Patients, was printed in the Journal of Parenteral and Enteral Nutrition (JPEN). JPEN is the research journal of the American Society for Parenteral and Enteral Nutrition (ASPEN).(2)

The study notes the following:

Limited data exist regarding the relationship between plasma 25-hydroxyvitamin D levels and duration of respiratory support. Our aim was to investigate whether vitamin D status at the time of intensive care unit (ICU) entry is related to duration of mechanical ventilation in critically ill surgical patients.(2)

Not enough vitamin D increases time needed for respiratory support among sick

The researchers examined data from a prospective cohort study involving 210 critically ill surgical patients to ascertain the effects that vitamin D levels have on duration of respiratory support. Finally, it was found that in such patients, plasma 25-hydroxyvitamin D levels measured on ICU admission were inversely related to the duration of respiratory support.(2)

Plasma 25-hydroxyvitamin D is caused by the liver converting the vitamin D that one gets from the sun, nutritional supplements and food. The quantity of it in the body is considered an extremely precise indicator of a men vitamin D degree. Overly-low levels are linked with a host of health problems ranging from osteomalacia, a mineralization defect in which bone mineral density falls, to the growth of specific types of cancer, high blood pressure, diabetes and deadly cardiovascular conditions.(3)

Asthma, COPD among troubles worsened by low vitamin D levels

Also and more relevant to this specific study appropriate vitamin D levels have been linked to developments in lung function, further strengthening the value of its supplementation.

Previous studies have delved into this very matter, with results demonstrating that vitamin D plays an important part in fostering respiratory health. One finding, as an example, honed in on the known effects of vitamin D on immune function… in relation to respiratory health. Its population-based study concluded that Vitamin D seems capable of inhibiting pulmonary inflammatory reactions while improving innate defense mechanisms against respiratory pathogens. Along with fostering the immune system complete, vitamin D was discovered to enhance lung function in those suffering from respiratory-inflammation illnesses like asthma and chronic obstructive pulmonary disease (COPD).(4)

Supplementation, diet, essential to getting more vitamin D

To ensure appropriate vitamin D levels, the Mayo Clinic says the recommended dietary allowance (RDA) for adults is 600 IU. For adults older than 70, 800 IU of vitamin D should be used up. Eggs, mushrooms and salmon are considered great vitamin D sources, as are nutritional supplements that come from a trustworthy source. Better yet, nutritional supplements joined with foods high in calcium or a mineral supplement are considered to further strengthen complete health.(5,6)

Being aware of vitamin D levels is, in addition, crucial when low amounts are affected but also when much of it exists in the body. When an individual has collected the vitamin in surplus vitamin D toxicity can happen. While uncommon, its a serious illness that can cause everything to nausea from kidney issues. Usually, too much of it in the body is due to taking it for more-than-standard durations exceeding that which was indicated by a medical professional to treat the deficiency.(7)
