WHAT IS VITAMIN B6 (PYRIDOXINE, PYRIDOXAL, AND PYRIDOXAMINE) TEST?

Vitamin B6 is a term that collectively refers to three water-soluble vitamins: pyridoxine, pyridoxal, and pyridoxamine. After absorption, pyridoxine is converted to the active forms of pyridoxal and pyridoxamine phosphates. These vitamins are found in many foods, including meats, egg yolks, fish, fowl, whole grains (such as wheat germ, rye meal, soybean meal, barley, soybeans, brown rice), and vegetables. Recommended Dietary Allowance for Americans is 3-4.9 mg/day. The B vitamins are important in the function of the central nervous system and heme synthesis, and they function as coenzymes in amino acid metabolism and glycogenolysis. Because vitamin B6 is partially destroyed by heat, overheating of infant formula makes infants particularly prone to vitamin B6 deficiency. A sign of vitamin B6 deficiency includes peripheral neuropathy, and a sign of toxicity is severe sensorimotor neuropathy.
