Introduction
Vitamin B6 is a water-soluble vitamin and is also known as pyridoxine. [3]
It is one of the most central molecules in the cells of living organisms. [1]
Humans cannot synthesise it and hence it should be obtained from the diet.

- Vitamin B6 bioavailability from a mixed diet is assumed to be around 75%. [1,2]

- The total vitamin B6 body stores are estimated to be around 167 mg. [7]
- Most of the body’s vitamin B6 is found in the muscles, approximately 80%, and about 5–10% is in the liver. [5]

- Vitamin B6 is oxidised in the liver and primarily excreted in the urine. [3]
