Lower Vitamin D Levels Linked to Higher Premature Death Rate
Researchers at the University of California, San Diego School of Medicine have found that people with lower blood levels of vitamin D were twice as likely to die prematurely as people with higher blood levels of vitamin D.
The finding was based on a systematic review of 32 previous studies that included analyses of vitamin D, blood levels and human mortality rates. The new study showed an association of low vitamin D with risk of premature death from all causes, not just bone diseases.The blood level amount of vitamin D associated with about half of the death rate was 30 ng/ml. An estimated two thirds if the US population has blood vitamin D levels below 30 ng/ml.
The average age when the blood was drawn for this study was 55 years; the average length of follow-up was nine years. The study included residents of 14 countries, including the United States , and data from 566,583. Based on the findings, it is wise to consult your physician when changed your intake of vitamin D and to have your blood level of 25-hydroxyvitamin D checked annually.
