“If vitamin D levels drop to 25 nmol / L, the risk of death increases by 25%”

Vitamin D is a nutrient necessary for normal muscle and bone development. Because it is synthesized in the body through the skin exposed to the ultraviolet rays of the sun, it is nicknamed the “sunshine vitamin”.
However, one study found that vitamin D deficiency was associated with mortality.
Therefore, the researchers noted that strategies need to be devised to reduce the risk of premature death associated with low vitamin D levels.
According to the medical community on the 26th, researchers from the University of South Australia in Australia recently announced the results of the causality analysis of vitamin D deficiency and mortality by monitoring 307,601 participants in the British biobank.
During the 14-year follow-up period, there were 18,700 deaths among subjects.
According to the research team, when the blood concentration of vitamin D rises from a low state to a normal level of 50 nmol / L (nanomoles per liter), the risk of death decreases dramatically.
Additionally, for all causes of death, including cancer, cardiovascular disease, and respiratory disease, the risk of death at a vitamin D concentration of 25 nmol / L was 25% higher than when the vitamin D concentration was 50 nmol. /L.
“Our study supports a causal relationship between vitamin D deficiency and mortality,” said the researchers. “Further research could identify a guideline better than 50 nmol / L and create strategies to reduce the risk of premature death associated with low vitamin D levels.” the researchers said. I need it, “she wrote.
However, the researchers added that the study was limited to the white European population and there were limitations in the lack of studies on participants with severe vitamin D deficiency.
On the other hand, vitamin D is synthesized in the body through the skin exposed to the ultraviolet rays of the sun. Sun exposure provides 90% of the vitamin D our body needs.
It is also found in fatty fish (salmon, tuna, mackerel), liver, egg yolk, and cheese among foods.
