An increased intake of the vitamins B6 and B12 may ward off depression, say scientists.
Researchers tracked 3,503 older adults for up to 12 years. The subjects were free of depression at the study onset. Over the course of the trial, 11% to 14% of subjects developed depression. Every 10-micrograms (mg) increase in daily B6 and B12 vitamins from food or supplements was associated with a 2% lower risk of depression. These findings held after adjustment for age, sex, race, education, income, and antidepressant medication use.
“Our results support the hypothesis that high total intakes of vitamins B6 and B12 are protective of depressive symptoms over time in community-residing older adults,” writes the study’s author.
