Vitamin B6 supplements are popular among people who want healthier heart and nervous system function. That’s because vitamin B6 (pyridoxine hydrochloride) may help the body to create neurotransmitters, such as serotonin, dopamine, and gamma-aminobutyric acid (GABA). Both serotonin and GABA help control anxiety, depression and feelings of pain. As it relates to cardiovascular health, vitamin B6 may have similar effects to folic acid in being able to support the normal metabolism of homocysteine which, if not metabolized, could negatively impact the cardiovascular system over time. While B6 is found in many of the foods we eat, having 2,940% of the recommended dietary Intake in one easy convenient tablet is a helpful for those who want to maintain optimal health.
