The beneficial effects of vitamin D supplementation in depressed adolescents

Statistical analysis revealed that the vitamin D supplementation group showed a significant reduction in depression scores compared with the control group, which showed no significant improvement. An intention-to-treat analysis and a per-protocol analysis were carried out, confirming the robustness of these results.

This study highlights the importance of vitamin D in mental health, particularly in adolescents living in areas where vitamin D deficiency is common. The mechanisms by which vitamin D influences depression include its ability to modulate pro-inflammatory cytokines and to protect against the depletion of dopamine and serotonin, two key neurotransmitters in the regulation of mood.

The results of this study are consistent with other research indicating that vitamin D supplementation can improve depression scores. For example, a study by Bahrami et al. in Iran showed similar improvements in adolescent girls who received a high dose of vitamin D. A meta-analysis by Vellekkatt and Menon also found that vitamin D supplementation had a positive impact on depression scores in individuals suffering from major depression.

To conclude, vitamin D supplementation represents a potentially effective, cost-effective and accessible intervention for improving the mental health of adolescents, particularly in low- and middle-income countries where micronutrient deficiencies are common.
