Associations of Dietary Intake of Vitamin B6 and Plasma Pyridoxal 5′‐Phosphate Level With Depression in US Adults: Findings From NHANES 2005–2010

Plasma PLP levels and dietary vitamin B6 intake in the highest quartiles are associated with a lower risk of depression. These findings support the promotion of a balanced diet rich in vitamin B6. However, future randomized controlled trials are necessary to confirm the effects of vitamin B6 supplementation on depression risk. We should aim for a healthy and balanced diet in terms of nutritional supplementation.
