4. Vitamin B3 (Niacin):
Niacin is essential for DNA repair, energy production, and the metabolism of carbohydrates, fats, and proteins. It also helps maintain healthy skin and nerves. Niacin is found in meat, fish, whole grains, and nuts .
5. Vitamin B5 (Pantothenic Acid):
Pantothenic acid is important for synthesizing coenzyme A, which is involved in fatty acid metabolism. It also plays a role in the synthesis of hormones and neurotransmitters. Good sources include avocados, whole grains, and eggs .
6. Vitamin B6 (Pyridoxine):
Vitamin B6 is involved in over 100 enzyme reactions, mainly related to protein metabolism. It also plays a role in cognitive development and immune function. Vitamin B6 can be found in poultry, fish, potatoes, and bananas .

9. Vitamin B12 (Cobalamin):
Vitamin B12 is necessary for red blood cell formation, DNA synthesis, and maintaining healthy nerve cells. It is found naturally in animal products such as meat, fish, poultry, eggs, and dairy. Vegetarians and vegans may need supplements to meet their B12 needs .
10. Vitamin C (Ascorbic Acid):
Vitamin C is a potent antioxidant that helps protect cells from oxidative damage. It is essential for collagen synthesis, wound healing, and immune function. Citrus fruits, strawberries, bell peppers, and broccoli are rich sources of Vitamin C .
11. Vitamin D:
Vitamin D is vital for calcium absorption and bone health. It also plays a role in immune function and reducing inflammation. The body can produce Vitamin D when exposed to sunlight, and it is also found in fortified foods, fatty fish, and eggs .
12. Vitamin E:
Vitamin E acts as an antioxidant, protecting cells from oxidative damage. It also supports immune function and skin health. Vitamin E is found in nuts, seeds, and green leafy vegetables .
13. Vitamin K:
Vitamin K is essential for blood clotting and bone metabolism. It helps synthesize proteins needed for blood coagulation and bone health. Vitamin K is found in green leafy vegetables, such as spinach and kale, and in fermented foods .
Conclusion:
These 13 vitamins—A, B1, B2, B3, B5, B6, B7, B9, B12, C, D, E, and K—are essential for maintaining health and supporting various bodily functions.
