Is Vitamin D Deficiency Associated with High Mortality Rates?
By now, most of us are aware of how vitamin D works. It’s called the sunshine vitamin because the sun is its number one source. When exposed to UVB rays, our bodies naturally produce vitamin D. Our bodies respond to being exposed to sun rays by converting a compound known as 7-dehydrocholesterol into vitamin D3.
We can get our recommended daily dose of vitamin D through sun exposure, diet —by including certain foods like eggs, oily fish, and more— or via vitamin D supplements, or a combination of all of those. Vitamin D provides a wide array of benefits. Still, if we are not getting enough vitamin D, we put ourselves at risk of becoming vitamin D deficient, which also carries health consequences.
Several studies and clinical trials —usually focused on older individuals who typically take vitamin D— have been conducted, which have concluded that there is a link between vitamin D deficiency and mortality. One particular study from the Department of Laboratory Medicine at the General Hospital of Vienna performed on records of patients between 1991 and 2011, which belong to people of an average of 51 years of age, and 31.5% of them were male.
According to this study, people 45 to 60 years of age with levels of vitamin D of 10nmol/L or less had a higher risk of death, while those of the same age who had vitamin D levels of 90nmol/L or above had a lower risk of mortality by 30-40%.
Supplementation Could Be the Key
If you lack vitamin D, taking vitamin D supplements could be what you need to prevent things like premature mortality. It is also an excellent way to ensure you start taking the proper amount of daily vitamin D from an early stage of life to prevent negative consequences in the future.
