Evidence supporting the use of: Vitamin B6
For the health condition: Memory and Brain Function
Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Vitamin B6 (pyridoxine) is involved in several biochemical processes essential for brain function, including neurotransmitter synthesis (such as serotonin, dopamine, and GABA), homocysteine metabolism, and overall neuronal health. There is scientific interest in the role of vitamin B6 in cognitive function, particularly in older adults and in the context of mild cognitive impairment (MCI). Some observational studies have associated low vitamin B6 levels with poorer cognitive performance and higher risk of cognitive decline. Additionally, vitamin B6, often in combination with other B vitamins (B12 and folic acid), has been investigated in randomized controlled trials to assess its effect on memory and cognitive function, largely due to its effect on lowering homocysteine—a risk factor for cognitive decline.
However, the overall evidence remains limited and mixed. While supplementation corrects deficiencies and may benefit cognition in people who are deficient, high-quality trials in healthy older adults or those with mild cognitive impairment have generally not shown significant improvements in memory or broader cognitive function from vitamin B6 supplementation alone. Most benefits are seen in correcting deficiencies rather than enhancing brain function in the general population. Thus, while there is a scientific rationale and some supporting evidence, it is not robust, and the effect size in non-deficient individuals is likely small.
