A new study shows that taking large doses of vitamin B6 tablets can reduce anxiety and depression. British scientists studied the effects of large doses of vitamin B6 on young people and found that after taking supplements every day for a month, they felt less anxious and depressed. The study, published in the journal Human psychopharmacology: clinical and experimental, shows that using supplements to change the level of brain activity can prevent or treat emotional disorders. "Brain function depends on a delicate balance between excitatory neurons that carry information and inhibitory neurons that prevent uncontrolled activity," said Dr. David field, of the school of psychology and clinical language sciences at the University of reading Vitamin B6 helps the body produce a specific chemical messenger that suppresses impulses in the brain. New research links this sedative effect with a reduction in participants' anxiety. Although previous studies have shown that multivitamins or marmalade (rich in vitamin B) can reduce stress levels, few studies have shown that the specific vitamins they contain produce this effect. New research focuses on the potential role of vitamin B6. As we all know, vitamin B6 can increase human production γ－ Aminobutyric acid (GABA), an important inhibitory neurotransmitter in the central nervous system. In the trial of this study, more than 300 participants were randomly assigned to take vitamin B6 or B12 supplements or placebo, and the actual intake was much higher than the recommended daily intake - about 50 times, taking one tablet per day for one month. Research shows that during the trial period, vitamin B12 has little effect compared with placebo, but vitamin B6 has a statistically significant difference. Visual tests at the end of the trial confirmed that participants taking vitamin B6 supplements had elevated GABA levels, supporting the hypothesis that B6 can reduce anxiety. The researchers observed subtle but harmless changes consistent with the controlled level of brain activity. The researchers said that the effect of vitamin B6 on anxiety was quite small compared with the expectation of drug treatment. However, nutrition based interventions produce far fewer adverse side effects than drugs, so people may prefer such interventions in the future. (outlook new era)
