Published in Nutrients
Methodology
Systematic review of randomised controlled trials of B vitamins, alone or in complexes, on mood, stress and depressive symptoms in adults.
Key Findings
B-vitamin supplementation, especially at higher doses and over longer durations, showed benefit for stress and mood in healthy and at-risk populations, while effects on clinical depression were inconsistent.
Conclusions
B-complex supplementation appears more useful for stress and general mood than for treating diagnosed depression.
Limitations
Substantial heterogeneity in formulations, doses and outcome measures; several included trials were industry funded.
Supplements Studied
B vitamin supplementation, particularly at higher doses and over longer periods, showed benefit for mood and stress outcomes in healthy and at-risk populations.
Outcomes Measured
Effects of B vitamins on clinical depression were inconsistent, while benefits for general mood and stress were more reliable.
