There are many ways our body uses vitamin B6 (pyridoxine-5-phosphate). This includes metabolizing the amino acids, fats, and sugars we eat into energy for our cells. It also plays an important role in creating neurotransmitters, sex hormones, and the hemoglobin within red blood cells. Certain health conditions appear to benefit with B6 supplementation including cardiovascular disease, nausea in pregnancy, carpal tunnel, and depression. There is an upper limit when taking vitamin B6 which makes it important to consult your naturopathic doctor to ensure you are on the correct dose.
