Vitamin B6


Essential Vitamin For Body And Mind


Vitamin B6 is a water-soluble vitamin. This means the body is unable to store it and a continuous supply is needed in the diet. Vitamin B6 is naturally found in many foods and is also added to a variety of fortified foods. It is important for helping your body make antibodies which are needed to fight a variety of diseases. Vitamin B6 is also plays a key role in maintaining normal nerve function, maintaining healthy glucose ranges, and hemoglobin production. Hemoglobin carries oxygen in red blood cells to body tissues. Those who are deficient in B6 can often develop a form of anemia. Vitamin B6 breaks down proteins in the body. Those who eat high amounts of protein will need more B6.
