Types and Functions of B Vitamins

1. Thiamine (B1)

Thiamine is essential for converting carbohydrates into energy. It also supports the nervous system by assisting in the production of neurotransmitters necessary for brain function.

2. Riboflavin (B2)

Riboflavin is involved in energy production from proteins, fats, and carbohydrates. It also plays a role in antioxidant activity, protecting cells from damage caused by free radicals.

3. Niacin (B3)

Niacin supports energy metabolism, helping convert food into usable energy. It also aids in DNA repair and plays a role in regulating cholesterol levels.

4. Pantothenic Acid (B5)

Pantothenic acid is crucial for synthesizing coenzyme A, which is involved in numerous metabolic pathways. It supports hormone production and assists in wound healing.

5. Pyridoxine (B6)

Pyridoxine is necessary for brain development and function. It helps produce neurotransmitters like serotonin and norepinephrine, which regulate mood and stress response.

6. Biotin (B7)

Biotin is essential for metabolism, particularly in the breakdown of fats, proteins, and carbohydrates. It supports healthy hair, skin, and nails.

7. Folate (B9)

Folate is vital for DNA synthesis and cell division. It is especially important during pregnancy for fetal development and helps prevent neural tube defects.

8. Cobalamin (B12)

Vitamin B12 is crucial for nerve function and the formation of red blood cells. It also plays a role in DNA synthesis and maintaining the myelin sheath that surrounds nerve fibers.

Benefits of B Vitamins
