Vitamin Reduces Anxiety and Depression Within One Month
A randomized clinical trial conducted by researchers from the University of Reading in the UK and published in the scientific journal Depression and Anxiety revealed that taking relatively high doses of vitamin B6 daily significantly alleviates symptoms of anxiety and depression in healthy adults. The results showed that the positive effects appear within just one month of regular use, without the acute side effects typically associated with conventional psychiatric medications.
Researchers subjected a group of young adults to a 28-day double-blind trial. Participants were randomly divided into three groups: the first received a placebo, the second received a high dose of vitamin B6 amounting to approximately 100 mg daily, and the third received vitamin B12. The group taking vitamin B6 recorded a statistically significant decrease in self-reported anxiety and depression scores compared to the placebo group.
The dosage used in the trial was approximately 50 times the recommended daily allowance. Researchers monitored participants throughout the intervention period using standardized psychological screening tools to measure changes in mood and stress levels.
Vitamin B6 plays a pivotal role in the central nervous system as a coenzyme in the synthesis of chemical messengers that regulate mood. The University of Reading team explained that high doses of this vitamin contribute to several neurological effects, most notably:
• Suppressing certain neural signals, thereby reducing hyperactivity in the nervous system.
This biochemical pathway offers a targeted alternative to conventional psychiatric medications, which typically work through serotonin or dopamine pathways. Vitamin B6 directly targets the inhibitory neurotransmitter responsible for dampening excessive brain activity.
Conversely, specialists have warned against the risks of long-term high-dose use of vitamin B6. The US National Institutes of Health reported that excessive consumption over extended periods may lead to sensory neuropathy, causing numbness and damage to peripheral nerves in the hands and feet. The officially recommended maximum daily dose for adults is much lower than the dosages used in the University of Reading trial.
Researchers advised individuals seeking to manage mild anxiety or depression symptoms through dietary modifications to consult a specialist physician before starting any high-dose regimen. They noted that natural sources of vitamin B6 include chickpeas, dark leafy vegetables, fish, poultry, and bananas, which are safer options for meeting basic nutritional needs for this vitamin.
These findings add to a growing body of research investigating vitamin B6 as a potential adjunctive treatment for mood disorders. The University of Reading continues to conduct broader studies, including an electroencephalography-based trial aimed at understanding the vitamin’s impact on neural activity in greater depth.
