Vitamin B6 is a water-soluble vitamin that is naturally present in many foods and also added to many others (or fortified). Vitamin B6 is also available in many dietary supplements, including protein powders and multivitamins.
It is the generic name for six chemical compounds with vitamin B6 activity: pyridoxine, an alcohol; pyridoxal, an aldehyde; and pyridoxamine, which contains an amino group; and their respective 5’-phosphate esters. Pyridoxal 5’ phosphate (PLP) and pyridoxamine 5’ phosphate (PMP) are the active coenzyme forms of vitamin B6.
The richest sources of vitamin B6 include meats, potatoes, and other starchy vegetables. It can also be found in many citrus fruits.
B vitamins are essential for the body to convert the food we eat into the energy we need to function. B vitamins are important for metabolism, brain and liver function, growth, and building blood cells, as well as for maintaining healthy hair, skin, and vision.
The Bottom Line – An essential B vitamin found naturally occurring in many foods.
Vitamin B6 Health Benefits
Vitamin B6 is essential for protein and amino acid metabolism which play keys roles in repairing the body, supporting the immune system, and contributing towards daily bodily functions including the brain and central nervous system.
Below is a list of the possible benefits we’ve found:
Vitamin B6 may reduce the risk of Cardiovascular Disease
Vitamin B6 is thought to help reduce the risk of cardiovascular disease. One trial which included more than 5,500 adults with known cardiovascular disease, found that supplementation for 5 years with vitamin B6 (50 mg/day), vitamin B12 (1 mg/day), and folic acid (2.5 mg/day) reduced homocysteine levels and decreased stroke risk by about 25% .
Vitamin B6 Can reduce your risk of certain cancers
Some research has associated low plasma vitamin B6 concentrations with an increased risk of certain kinds of cancer.
For example, a meta-analysis of prospective studies found that people with a vitamin B6 intake in the highest quintile had a 20% lower risk of colorectal cancer than those with an intake in the lowest quintile. 
Whilst more research in this area is needed to confirm if there is a direct correlation between the risk of cancer and B6 levels, preliminary evidence does seem to suggest that Vitamin B6 is beneficial when it comes to reducing your risk of certain cancers, such as colorectal.
