DID Press: Recent studies published between 2024 and 2025 highlight the crucial role of B‑group vitamins — particularly Vitamin B6, B9 (folate), and B12 — in regulating mood, reducing anxiety, and maintaining brain health.
A 2025 study found that a diet rich in these vitamins is associated with a lower risk of cognitive decline and dementia. Research on healthy adults also suggests that regular intake of B vitamins over several months can improve overall mental well‑being and psychological health.
In individuals with depression, low blood levels of these vitamins have been linked to cognitive impairments and more severe depressive symptoms. Clinical trials have shown that Vitamin B6 supplementation can significantly reduce anxiety and feelings of depression, possibly by enhancing inhibitory neurotransmitter (GABA) activity in the brain.
Nutritionists and mental health specialists recommend a balanced diet rich in B vitamins — including sources such as meat, eggs, dairy, leafy greens, whole grains, and legumes — and, when necessary, physician‑supervised supplementation. This is especially important for high‑risk groups such as vegetarians, the elderly, and individuals with mental health conditions, as it may support brain health and improve mood.
