Exploring the impact of individual UVB radiation levels on serum 25-hydroxyvitamin d in women living in high versus low latitudes : a cross-sectional analysis from the D-SOL study

Vitamin D can be synthesized in the skin via sunlight exposure as well as ingested through diet. Vitamin D deficiency is currently a major global public health issue, with increasing prevalence in both low and high latitude locations. This cross-sectional analysis aimed to compare the intensity of i...
