Vitamin B-6 is one of the most popular members of the B vitamin family, as it participates in many bodily functions, such as digestion, red blood cell production, fluid retention, sodium-potassium balance, food metabolism, antibody production, brain function, and nucleic acid production. Additionally, it can help reduce symptoms of asthma and carpal tunnel syndrome.
Vitamin B-6 is found in nature, mainly in fresh vegetables. Once absorbed by red blood cells, it is converted into pyridoxal phosphate and pyridoxine. It mainly acts by activating the enzymes involved in more than 100 reactions that affect protein, fat, and carbohydrate metabolism. Also, pyridoxal phosphate plays an important role in the synthesis of neurotransmitters and the metabolism of various vitamins (e.g., in the conversion of tryptophan to niacin) and in the synthesis of hemoglobin and sphingosine.
Clinical studies confirm that B-6 plays a crucial role in regulating homocysteine levels. High homocysteine impairs and inhibits the formation of the three main components of arteries (collagen, elastin, and proteoglycans) and is directly related to heart problems. Additionally, increased levels of homocysteine are associated with the onset of Alzheimer's disease, schizophrenia, and multiple fractures in mainly elderly individuals.
