Vitamin B6 (pyridoxine) has been studied in relation to Alzheimer’s disease (AD) due to its role in brain health, neurotransmitter synthesis, and homocysteine metabolism.
Biological Role of Vitamin B6
-can act as a potent antioxidant
-Essential for the production of serotonin, dopamine, GABA, and norepinephrine.
-Homocysteine regulation: B6 is a cofactor in the conversion of homocysteine to cysteine.
Elevated homocysteine levels are linked to increased AD risk and brain atrophy.
-Anti-inflammatory effects: B6 may modulate inflammation, a key factor in neurodegeneration.
-Myelin and cognitive function: Involved in myelin formation and synaptic plasticity.
-higher vitamin B6 intakes have been associated with greater grey matter volume
Cognitive support / Homocysteine lowering 10–50 mg/day Often combined with B12 and folate

| Homocysteine is a sulfur-containing amino acid produced during the metabolism of methionine.
Elevated homocysteine levels and alterations in its metabolic enzymes have been associated with various pathological processes, including oxidative stress, DNA damage, and inflammation. -Elevated plasma homocysteine levels (hyperhomocysteinemia) are a well‐established risk factor for cardiovascular diseases. -Some studies have suggested that high levels of homocysteine might be associated with an increased risk of certain cancers. -Vitamins like folate, B6, and B12 are key regulators of homocysteine metabolism, some research has examined whether supplementation might modulate cancer risk. However, clinical outcomes have been mixed and further research is needed. -Various clinical trials have shown that the oral supplementation of folic acid, B6, and B12 vitamins significantly lowers circulating homocysteine levels. |
