A new clinical trial published in the Journal of the American Geriatrics Society found that vitamin D supplementation acute respiratory infections (ARI) in nursing home residents.
The researchers aimed to determine whether vitamin D supplementation had an effect on respiratory infections among 107 nursing home residents. A total of 55 participants received high doses of vitamin D monthly (averaging between 3,300-4,300 IU/day), and 52 participants were given lower monthly doses (averaging between 400-1000 IU/day). The participants were assessed over a period of 12 months.
The researchers found that those who received the higher doses of vitamin D experienced nearly half the incidence ARIs compared to those who received the lower doses of vitamin D. Additionally, the participants who received the higher dosage of vitamin D experienced a 2-fold increase in falls; though, no significant difference was observed in fractures due to falls between the two groups.
Ginde, the lead researcher of the study, concluded,
“This finding requires a confirmatory trial, including whether high daily doses of vitamin D, rather than high monthly doses, makes patients less likely to fall,”
“If our results are confirmed by a larger trial, high dose vitamin D, ideally using daily dosing to minimize fall risk, has the potential for substantial public health benefit through ARI prevention for the large and growing population of long term care residents.”
