Research indicates that vitamin D supplementation may decrease depressive symptoms during the winter months.
In this study, nine women with serum vitamin D levels <40 ng/ml were administered the Beck Depression Inventory (BDI)-II. After vitamin D3 supplementation, six of these women completed the BDI-II and had their serum vitamin D levels reassessed.
Vitamin D supplementation was associated not only with an increase in the serum D levels by an average of 27 ng/ml but also with a decline in the BDI-II scores of an average of 10 points.
This study suggests that supplemental vitamin D3 reduces depressive symptoms.
研究表明，补充维生素D可能会减轻冬季的抑郁症状。
在本研究中，对9名血清维生素D水平低于40 ng/ml的女性进行了贝克抑郁量表（BDI）-II测试。补充维生素D3后，其中6名女性完成了BDI-II测试，并重新评估了她们的血清维生素D水平。
补充维生素D不仅使血清D水平平均升高27 ng/ml，还使BDI-II得分平均下降10分。
本研究表明，补充维生素D3可减轻抑郁症状。
