Who Benefits From Vitamin D?
Studying the expression of genes that are dependent on vitamin D makes it possible to identify individuals who will benefit from vitamin D supplementation, shows a University of Eastern Finland study published recently in PLoS One.
Population-based studies have shown that vitamin D deficiency may increase the risk for chronic diseases and weaken the body's immune system. In the present study carried out at the University of Eastern Finland, Kuopio, the study participants were given a daily dose of either 40 or 80 micrograms of vitamin D, or a placebo, over a course of 5 months during Finnish winter. The results showed that the expression of vitamin D dependent genes in adipose tissue and monocytes, i.e. white blood cells, correlated only in half of the study participants with their vitamin D concentrations in the blood.
