Vitamin D may not reduce risk of depression
New research has found no evidence that vitamin D may help reduce risk of depression—a finding that counters those of previous studies.
In the study, scientists from Columbia University Medical Center (CUMC) in New York looked at data from seven clinical trials on the link between vitamin D and depression. An analysis of data involving more than 3,000 people revealed that vitamin D supplementation alone had no overall impact on depression.
The study’s results, published in the journal Psychosomatic Medicine, suggest differing implications depending on a person’s health factors. People with vitamin D deficiency, for example, may benefit from taking vitamin D supplements. Additionally, people who have been diagnosed with clinical depression and take antidepressants may have improved symptoms after taking vitamin D supplements. However, researchers said that those effects cannot be confirmed without further trials.
There remains much uncertainty surrounding health benefits of vitamin D, as previous studies have provided conflicting evidence as to whether vitamin D may help reduce risk of heart attack, stroke and different types of cancer. The researchers involved in the new study said they hope that their results will encourage new trials to help develop more conclusive findings.
