The B-vitamins, often referred to as the B-complex vitamins, are a group of water-soluble vitamins that play important roles in various bodily functions. Each B-vitamin has unique functions, but collectively, they are essential for overall health and well-being. Here’s what the B-vitamins do for you:

1. B1 (Thiamine): Thiamine is essential for converting carbohydrates into energy and for the proper functioning of the nervous system.
2. B2 (Riboflavin): Riboflavin is important for energy production, the metabolism of fats, drugs, and steroids, and the maintenance of healthy skin, eyes, and nerve function.
3. B3 (Niacin): Niacin is involved in energy metabolism, DNA repair, and the maintenance of healthy skin, nerves, and digestion.
4. B5 (Pantothenic Acid): Pantothenic acid is essential for the synthesis of fatty acids, the production of red blood cells, and the metabolism of various nutrients.
5. B6 (Pyridoxine): Pyridoxine is important for the metabolism of amino acids, the formation of neurotransmitters, and the regulation of mood and sleep.
6. B7 (Biotin): Biotin is crucial for fatty acid synthesis, energy metabolism, and the health of skin, hair, and nails.
7. B9 (Folate/Folic Acid): Folate is essential for DNA synthesis and repair, cell division, and the prevention of neural tube birth defects during pregnancy.
8. B12 (Cobalamin): Cobalamin is involved in the formation of red blood cells, DNA synthesis, and the maintenance of a healthy nervous system.

Collectively, the B-vitamins play key roles in energy metabolism, the conversion of food into energy, the formation of blood cells, the maintenance of skin and nerve health, and various other metabolic processes. They are essential for overall health and should be obtained through a balanced diet or supplements if necessary. Each B-vitamin has its own specific functions, and a deficiency in any of them can lead to a range of health issues.
