What is Vitamin B6?
Vitamin B6 is a water-soluble B vitamin essential in over 100 enzymatic processes throughout the body.1 For example, this vitamin is involved in the formation of red blood cells, immune system cells, nerve cells, proteins, and in the production of energy.1,2
Benefits of Vitamin B6
Vitamin B6 may, with other B vitamins, reduce risk factors of cardiovascular disease.1–4 Vitamin B6 deficiency, typically occurring with deficiencies in other B vitamins (e.g. folate, B12), may result in anemia.1,3 Thus, adequate intake of vitamin B6 may help reduce the risk of anemia in some people. Vitamin B6 helps make another B vitamin called niacin from the amino acid tryptophan, which can be an important source of this vitamin.1 Furthermore, vitamin B6 may play a role in cognitive function as it is involved in myelin formation (the covering of nerve cells) and in the production of neurotransmitters such as dopamine and serotonin.1,3
Foods High in Vitamin B6
Vitamin B6 can be found naturally in many foods including 100% orange juice. Significant amounts of vitamin B6 can be found in potatoes, chickpeas, meat, poultry, fish, avocados, and bananas.
An 8-ounce glass of 100% orange juice supplies 6-11% of the recommended Daily Value for vitamin B6.*
As part of a well-balanced diet low in saturated fat and cholesterol, vitamin B6 with folate and B12 may reduce the risk of cardiovascular disease.

- Breastmilk B6 concentrations are dependent upon maternal intake.1,2
- Vitamin B6 in combination with folate and B12 may help reduce the amino acid homocysteine in your body, which is linked to cardiovascular disease.1-4
