Vitamin B6, also known as pyridoxine, pyridoxal or pyridoxamine, is necessary for optimal health and wellness. Because vitamin B6 cannot be produced by the human body, it must be obtained through your diet. Vitamin B6 deficiency is not common in the United States -- it is most likely to occur in elderly persons or people with diets severely lacking in the vitamin. See your doctor to determine whether you need a vitamin B6 supplement.
Nervous System Function
Vitamin B6 helps the body make neurotransmitters, which are responsible for transferring messages between nerve cells in the body. Formation of neurotransmitters aids in the production of hormones like serotonin, which influences mood, and melatonin, which helps regulate sleep patterns, according to University of Maryland Medical Center. Researchers continue to investigate whether or not inadequate B6 levels play a large role in the development of diseases related to the nervous system, such as Parkinson's, chronic pain, seizures, depression and headaches.
Formation of Hemoglobin
The body also uses vitamin B6 to produce hemoglobin, which carries oxygen to body tissues. Specifically, vitamin B6 helps the body produce heme, which is one of the primary components of hemoglobin, which is found in the red blood cells. A low hemoglobin count may be related to vitamin B6 deficiency. Inadequate amounts of vitamin B6 can result in vitamin deficiency anemia, which results from low hemoglobin production. Vitamin deficiency anemia is commonly seen in older adults, according to the National Anemia Action Council.
Disease Prevention
Vitamin B6 may aid in the prevention of several chronic diseases, due to its role in the development and function of organs and other body parts, like the eyes and liver. According to the University of Maryland Medical Center, vitamin B6 deficiency may increase your chances of developing heart disease. Vitamin B6 lowers levels of homocysteine, which may contribute to heart disease when it is present in very high levels. Very low levels of vitamin B6 may also contribute to the development of coronary artery disease. Studies continue to investigate whether B6 supplementation can help prevent or treat carpal tunnel syndrome, rheumatoid arthritis and premenstrual syndrome. Vitamin B6 also supports the development of healthy skin and hair, and helps the body metabolize fats and proteins.
Sources and Recommended Intake
In addition to taking a dietary supplement, you can ensure that you obtain adequate amounts of vitamin B6 by consuming certain food sources. These include legumes, vegetables, cereal grains, potatoes, milk, eggs and cheese. The Recommended Daily Allowance varies based on age and gender. Males and females ages 19 to 50 are advised to consume 1.3 mg each day. Adult men over age 50 need 1.7 mg each day, and women need 1.5 mg per day.
