The power of vitamin B: function, deficiency & nutrition

Vitamin B is a group of essential nutrients that play a crucial role in health and wellbeing. This post explores the different types of vitamin B, their importance to the body and how to ensure you get enough of them to realise their full potential.

What is vitamin B?

Vitamin B, also known as the B complex, is a group of water-soluble vitamins that support a variety of important functions in the body. These vitamins play a key role in energy production, supporting the nervous system, promoting healthy skin and metabolising proteins, carbohydrates and fats.

The different types of vitamin B:

• Vitamin B1 (Thiamin): Thiamine is important for energy production, nervous system function and carbohydrate metabolism.
• Vitamin B2 (Riboflavin): Riboflavin supports energy metabolism, skin health and promotes tissue growth and repair.
• Vitamin B3 (Niacin): Niacin plays a role in energy production, nervous system function and supporting healthy cholesterol levels.
• Vitamin B5 (Pantothensäure): Pantothenic acid is important for hormone synthesis, energy production and the formation of red blood cells.
• Vitamin B6 (Pyridoxin): Pyridoxine supports the formation of neurotransmitters, the metabolism of amino acids and the function of the immune system.
• Vitamin B7 (Biotin): Biotin is important for healthy skin, hair and nails, as well as for the metabolism of carbohydrates and fats.
• Vitamin B9 (Folsäure): Folic acid is crucial for cell division, the formation of red blood cells and prenatal health.
• Vitamin B12 (Cobalamin): Cobalamin supports the formation of red blood cells, the function of the nervous system and DNA synthesis.

The importance of vitamin B for health

Vitamin B plays a crucial role in health and well-being as it supports various vital functions in the body. Here are some important benefits of vitamin B:

• Energy production: Vitamin B is essential for the metabolism of carbohydrates, fats and proteins, which means that it helps your body to obtain energy from food.
• Nervous system function: Vitamin B is essential for the health of the nervous system and supports communication between nerve cells.
• Skin health: Some forms of vitamin B, such as biotin (B7) and riboflavin (B2), are important for healthy skin, hair and nails.
• Blood formation: Vitamin B12 and folic acid are crucial for the formation of red blood cells and the prevention of anaemia.
• DNA synthesis: Vitamin B12 plays an important role in the synthesis of DNA and RNA, which is essential for cell growth and division.

Causes of vitamin B deficiency

There are many reasons for vitamin B deficiency. Inadequate intake through nutrition is one of the main reasons. Vegetarians and vegans who avoid animal products may be at increased risk of vitamin B deficiency, as many B vitamins are found mainly in animal foods. In addition, certain medical conditions such as gastrointestinal disorders, alcoholism and pregnancy can lead to increased requirements or reduced absorption of vitamin B. Taking certain medications such as antacids, antibiotics and anticonvulsants can also impair the absorption of vitamin B and lead to a deficiency. It is important to take the symptoms of vitamin B deficiency seriously and seek medical advice if necessary to determine the underlying cause and take appropriate action.

• Insufficient intake through nutrition
• Vegetarian or vegan diet
• Gastrointestinal disorders
• Alcoholism
• Pregnancy and breastfeeding
• Medication (e.g. antacids, antibiotics, anticonvulsants)
