Why is vitamin B important?
Each B vitamin is an essential micronutrient.2 This means that B vitamins play key roles in enabling specific pathways in your body and generating other important substances the body needs.2 These are essential for keeping your cells working properly and maintaining homeostasis (your body’s ability to keep you alive in a range of conditions).2
So, in short, B vitamins are important for maintaining your body’s ability to keep you alive in a range of external conditions.2,3 Specifically:4
- thiamin (vitamin B1), riboflavin (vitamin B2), niacin (vitamin B3) and pantothenic acid (vitamin B5) – help your body to release energy from food and support the proper functioning of your nervous system
- pyridoxine (vitamin B6) – supports your body to store and use the energy from protein and carbohydrates and to create haemoglobin, which transports oxygen around the body
- biotin (vitamin B7) – helps to make fatty acids
- folate and folic acid (vitamin B9) – help your body to create healthy red blood cells and reduce the risk of birth defects in unborn babies
- cobalamin (vitamin B12) – helps your body to release the energy you get from food, use folate (vitamin B9), make red blood cells and maintain a healthy nervous system
Consequently, most of these ‘family members’ play a key role in helping your body metabolise food and manage its energy levels. Some studies even suggest that B vitamins are associated with slowed cognitive decline.4,5
However, the only B vitamin the body can produce itself is biotin (B7), in small amounts, which is why we need to make sure we’re taking B vitamins – either through our food or supplementation.1
