You really need B vitamins
The B vitamins are a group of eight water-soluble vitamins. They are coenzymes in a variety of metabolic processes in the body, and often work together—though each has a unique role as well. B vitamins are critical for building and repairing DNA and RNA, for producing energy, supporting mitochondrial function, and for synthesizing neurochemicals. And because they are involved in so many processes, deficiencies in B vitamins can lead to many problems. Are you getting enough B vitamins?
Vitamin B6 - pyridoxine
B6 represents a group of several compounds that play an important role in energy metabolism (especially protein metabolism). The most active form of which is pyridoxal 5’-phosphate (P5P), which is the form found in animal products. B6 insufficiency is relatively common, with some symptoms including poor sleep, poor mood, numbness and tingling, and anemia. Certain conditions (inflammation, certain drugs, etc) can increase needs for B6. Checking your status is a good way to know where you stand.
