New study shows evidence 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.
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.
