The neurotransmitters dopamine, serotonin, and gamma-aminobutyric acid (GABA) play critical roles in regulating your mood, and
vitamin B6 is a crucial component in these chemical messengers. Research has linked the non-essential amino acid homocysteine to depression, and
vitamin B6 reduces the levels of this harmful amino acid throughout your body.
When you don’t have enough vitamin B6 in your system,
you’re twice as likely to get depressed. Therefore research suggests there is a link between vitamin B6 and mood.
Homocysteine is an
indicator of Alzheimer’s disease, so when you consume enough vitamin B6, which contributes to normal homocysteine metabolism, this may have beneficial effects on your neurological health.
The role of vitamin B6 in producing neurotransmitters may also help with the symptoms of premenstrual syndrome (PMS). One study found that
women who take vitamin B6 daily are less likely to report common PMS symptoms such as irritability and depression.
Vitamin B6 helps your body produce hemoglobin. Therefore, when you’re deficient in pyridoxine,
you’re more likely to become anaemic, and so consuming adequate vitamin B6 in your diet is important to support red blood cell production.
Research has linked low vitamin B6 levels with an increased risk of
developing coronary artery disease.
Many women suffer from intense nausea when they’re pregnant. While some people write this off as simple morning sickness, the symptoms of this condition can be debilitating for some pregnant women. Thankfully,
pyridoxine appears to reduce nausea during pregnancy.
