Vitamin B6 is among the B-complex vitamins, which are nutrients that each fulfills a different function and role in the body. In the case of vitamin B6, it is required for the brain to synthesize serotonin and norepinephrine. Both serotonin and norepinephrine are substances produced by the brain as chemical “triggers,” affecting moods. Vitamin B6 is also known to play a role in the formation of myelin, a material that forms a layer around neurons in the brain. These effects make vitamin B6 essential in the normal functioning of the brain and nervous system.
Heredetary sideroblastic anemia is a condition wherein the body has sufficient iron, but cannot incorporate the mineral into the hemoglobin. Vitamin B6 has been shown in numerous clinical trials to combat this problem. In particular, vitamin B6 supplements have been found to be both effective and generally safe to use as a means of combating the effects of the condition. Note that despite the numerous safety trials, it is still recommended that a doctor be consulted before taking vitamin B6 to combat the condition.
Due to the effect that vitamin B6 has on serotonin levels in the brain, it is believed that it may also play a role in depression. Clinical depression is believed to be caused by a drop in serotonin levels in the brain, and vitamin B6 has been found to trigger the areas of the brain that produce the neurochemical. The current data does not show that vitamin B6 can cause the brain to produce enough serotonin to mimic the effects of an antidepressant, but further research is underway. Researchers believe there may be potential in vitamin B6 as an avenue of research, if not as a potential treatment, for antidepressant medications.
Vitamin B6 also helps in preventing or alleviating peripheral neuropathy, which is the term used to indicate damage to the nerves in the nervous system. This type of damage can be caused by various conditions, such as leprosy, certain genetic diseases, liver failure, and some types of physical trauma. Vitamin B6 is not a cure for any of these conditions, but it can be used to ease the symptoms caused by the nerve damage. Vitamin B6 deficiencies also result in a reduction of myelin in some individuals, and the easiest treatment is regular dosing of vitamin B6 to restore the appropriate levels in the body.
Cycloserine is an antibiotic that can sometimes result in anemia as a side effect. Various studies have shown that vitamin B6 is capable of minimizing these side effects. Test data showed that taking vitamin B6 supplements at the same time or in parallel to cycloserine can reduce the damage caused by the antibiotic without denying patients the beneficial effects. Some have noted that those taking the antibiotic have higher daily requirements of vitamin B6 than the average person. Research on whether or not vitamin B6 can help in anemia in general is underway. Consultation with a medical professional should be undertaken prior to taking vitamin B6 while anemic.
Similar to cycloserine, vitamin B6 may also be used as a means of preventing the side effects of neuroleptic medication. Neuroleptics are medications used to combat certain psychiatric disorders, and the movement disorder akathisia is a notable side effect. Vitamin B6 has been studied as a means of treating the movement disorder, with the data focusing on using vitamin B6 on schizophrenic and schizoaffective patients. Preliminary testing indicated that high doses were useful in the treatment, but the medical community is waiting on further study to verify the results.
In the metabolic process, vitamin B6 also plays a significant role. It is found to help in the synthesis and breakdown of amino acids used in the body. Vitamin B6 is helpful for the conversion of tryptophan into niacin, which is better known as vitamin B3. Low levels of vitamin B6 are known to hinder this conversion in the body.
Vitamin B6 also plays a vital role in the process called gluconeogenesis. This is the process that the body uses to turn the molecules of food into simpler carbohydrates that the cells burn for energy. Vitamin B6 causes reactions within the body that are found to be essential in providing amino acids for the process. Vitamin B6 is also found to be connected to glycogen phosphorylase, an enzyme that is necessary for the conversion process to occur.
