A group of researchers from the University of Guelph studied the validity of a mobile app to track vitamin D and calcium intake. Findings from the study are published in the Journal of Nutrition Education and Behavior

RELATED: How Common is Vit D Toxicity With Supplements?

Adults in Canada have shown to be consistently deficient in dietary vitamin D, which is partially due to low vitamin D synthesis from the sun during the fall and winter at Canadian latitudes. So researchers evaluated use of the Vitamin D Calculator app by enrolling 25 men and 25 women between ages 18-25. Participants were instructed to use the app to record their intake of vitamin D- and calcium-containing foods and beverages, as well as their sunlight exposure for 3 days. When participants orally recalled their intake after the 3-day period, the mean vitamin D and calcium intake as estimated by the app were significantly positively correlated and not significantly different from the recalls; this validated the use of the app to track dietary intake

Tracking intake is important in helping inform patients about potential deficiencies though it is not diagnostic of vitamin D status.
