Low Vitamin B Intake Links with Depression in Elderlies

In a recent study, it was revealed that low intakes of Vitamin B are said to contribute to depression in some people particularly in older adults.

In a recent study published in the American Journal of Clinical Nutrition, the researchers discovered a little supporting evidence that low intake of Vitamin B contributes to depression in older adults.

During the said study, the researchers observed whether certain dietary consumptions of Vitamin B6, Vitamin B12 and Folic Acid linked with symptoms of depression.

The study involved some 3,503 adult participants aged 65 and older who were observed over an average of 7.2 years. Their vitamin intakes from diet and supplements were evaluated through food frequency questionnaires, and the presence of depression was assessed periodically through a standardized version of the Center for Epidemiologic Studies Depression scale.

After 12 years of examination, it appeared that higher Vitamin B intakes, which includes supplementation) were linked with a lower risk of depressive symptoms. The reduced risk remained after adjusting for age, sex, race, education, income and use of anti-depressant medication. The risk of developing symptoms of depression decreased by 2 percent for every 10 mg increase in daily Vitamin B6 consumption. And the same effect was indeed true for every 10 µg increase in Vitamin B12 consumption. Nevertheless, increased intakes of Vitamin B through food consumption alone did not significantly reduce the risk of depression.

Apparently, both Vitamin B6 and Vitamin B12 play a significant role in healthy nervous system function. However, since older adults already have difficulty absorbing the Vitamin B12, which are naturally present in food, fortified foods and supplements are necessary to reach its beneficial levels.

The result of the said study highlights the Vitamin B6 and B12’s protective capability against depressive symptoms in older adults.
