- Food Sources: Whole grains, legumes, pork, nuts, and seeds.
2. Vitamin B2 (Riboflavin):
- Function: Riboflavin is involved in energy production, metabolism, and the maintenance of healthy skin and eyes.
- Food Sources: Dairy products, lean meats, eggs, legumes, and leafy green vegetables.
3. Vitamin B3 (Niacin):
- Function: Niacin is essential for energy production, DNA repair, and the function of the nervous system.
- Food Sources: Meat, poultry, fish, whole grains, legumes, and nuts.
4. Vitamin B5 (Pantothenic Acid):
- Function: Pantothenic acid is involved in energy production, hormone synthesis, and the metabolism of fats, proteins, and carbohydrates.
- Food Sources: Meat, poultry, fish, dairy products, whole grains, legumes, and vegetables.
5. Vitamin B6 (Pyridoxine):
- Function: Pyridoxine plays a role in amino acid metabolism, the production of neurotransmitters, and the synthesis of red blood cells.
- Food Sources: Meat, fish, poultry, potatoes, bananas, and fortified cereals.
6. Vitamin B7 (Biotin):

- Food Sources: Eggs, nuts, seeds, organ meats, sweet potatoes, and certain fruits and vegetables.
7. Vitamin B9 (Folate or Folic Acid):
- Function: Folate is crucial for DNA synthesis, cell division, and the production of red blood cells. It is especially important during pregnancy for fetal development.
- Food Sources: Leafy green vegetables, legumes, fortified grains, citrus fruits, and liver.
8. Vitamin B12 (Cobalamin):
- Function: Cobalamin is involved in DNA synthesis, red blood cell production, nervous system function, and energy metabolism.
- Food Sources: Animal-based foods such as meat, fish, poultry, eggs, and dairy products. Fortified foods and supplements are options for vegetarians and vegans.
9. Choline:
- Although not technically a B vitamin, choline is often included as part of the B complex. It supports brain health, cell structure, metabolism, and liver function.
- Food Sources: Eggs, liver, fish, meat, poultry, legumes, nuts, and cruciferous vegetables.
These B complex vitamins are generally available through a balanced diet that includes a variety of foods. However, certain individuals, such as pregnant women, vegetarians, older adults, and individuals with certain medical conditions, may benefit from supplements or fortified foods to meet their specific needs.
It's important to note that excessive intakes of some B vitamins may have adverse effects. If you have specific concerns about your B vitamin intake, it's best to consult with a healthcare professional or registered dietitian for personalized advice based on your unique needs.
