What is Vitamin B6?
Vitamin B6, also known as pyridoxine, is one of the eight B vitamins. It is a water-soluble vitamin that plays a crucial role in maintaining overall health and wellbeing. As the body cannot produce vitamin B6, it must be obtained through diet or supplements.
Vitamin B6 is essential for a wide range of bodily functions. It helps to convert food into energy, supports the nervous system, and aids in the production of red blood cells. Additionally, vitamin B6 is involved in the synthesis of neurotransmitters such as serotonin and dopamine, which regulate mood and behaviour. It also helps to reduce inflammation and support the immune system.
Vitamin B6 is involved in over 100 enzyme reactions in the body, which help to metabolise amino acids, carbohydrates, and lipids. It is also important for cognitive development and function, immune system health, and red blood cell formation.
There are three forms of vitamin B6: pyridoxine, pyridoxal, and pyridoxamine. All three forms are converted to pyridoxal 5-phosphate (PLP), which is the active form of vitamin B6 in the body.
Vitamin B6 is found in a variety of foods, including meat, fish, poultry, beans, nuts, and whole grains. The recommended daily amount of vitamin B6 for adults under 50 years old is 1.3 milligrams. After age 50, the recommended daily amount is 1.5 milligrams for women and 1.7 milligrams for men.
A deficiency in vitamin B6 can lead to several health problems, including anaemia, skin rashes, and neurological symptoms such as depression and confusion. However, it is rare to have a deficiency in vitamin B6, as it is found in many common foods.
In this article, I will explore it’s many benefits, including its role in brain function, immune health, and metabolism. I will also discuss the best dietary sources of vitamin B6, as well as the potential risks and side effects of consuming too much or too little of this essential nutrient.

Benefits of Vitamin B6
Vitamin B6 is a water-soluble vitamin that plays a vital role in the body. It is involved in over 100 enzymatic reactions and is essential for many bodily functions.
What does Vitamin B6 do in the body?
Vitamin B6 is involved in many processes in the body, including:
- Protein metabolism: It is involved in the metabolism of amino acids, which are the building blocks of proteins. It helps to convert one amino acid, called homocysteine, into another amino acid, called cysteine. This process helps to reduce the levels of homocysteine in the blood, which is important for heart health.
- Red blood cell formation: It is essential for the formation of red blood cells. It helps to produce haemoglobin, which is the protein in red blood cells that carries oxygen around the body.
- Immune function: It is important for a healthy immune system. It helps to produce antibodies, which are proteins that help to fight off infections.
- Nervous system function: It is involved in the production of neurotransmitters, which are chemicals that transmit signals in the brain. It is also important for the synthesis of myelin, which is the protective coating around nerve fibres.
What is the recommended daily intake of Vitamin B6?
The recommended daily intake of Vitamin B6 varies depending on age and gender. According to the UK Department of Health, the recommended daily intake is:
- 1.4mg/day for adult men
- 1.2mg/day for adult women
