Vitamin B6
(Pyridoxine)
Vitamin B6 (pyridoxine) is a water-soluble vitamin essential for enzymatic reactions in metabolism, neurotransmitter synthesis, immune support, and hormone balance.
Vitamin B6, present as pyridoxal phosphate in the body, is indispensable for metabolism of amino acids, synthesis of neurotransmitters, red blood cell formation, and supporting immune and nervous system health.
The essential roles of vitamin B6 in metabolism, neurotransmitter synthesis, and immune function are well-documented, with robust evidence for deficiency symptoms and clinical use for pregnancy-related nausea. Supplementation beyond dietary intake is effective in B6 deficiency states and for select therapeutic purposes.
Supports neurotransmitter synthesis and mood regulation
StrongVitamin B6 is crucial for the production of neurotransmitters such as serotonin, dopamine, and GABA, which are involved in mood, sleep, and cognitive function. Deficiency can cause mood disturbances and cognitive symptoms.
Helps relieve nausea and vomiting in pregnancy (morning sickness)
StrongSupplemental B6 is recommended as a first-line therapy for mild to moderate nausea in pregnancy, supported by clinical guidelines and research.
May reduce symptoms of premenstrual syndrome (PMS)
ModerateShort-term use of vitamin B6 at moderate doses can decrease PMS symptoms such as mood swings, irritability, and bloating in some women.
Contributes to maintenance of normal homocysteine levels and heart health
ModerateB6, along with folate and B12, helps regulate homocysteine, an amino acid linked to cardiovascular risk; deficiency is associated with high homocysteine.
Promotes immune system function
StrongVitamin B6 supports the production and function of lymphocytes and interleukin-2, important for immune response. Low B6 can weaken immune defenses.
