What are vitamins?

Definition of vitamins

Vitamins are organic compounds required in small amounts for normal growth, development, and maintenance of bodily functions. They are essential for various physiological processes, such as energy production, immune function, and cell growth. Vitamins can be classified into two categories: fat-soluble vitamins (A, D, E, and K) and water-soluble vitamins (B vitamins and vitamin C).

Classification of vitamins

Vitamins are classified based on their solubility in either fat or water. This classification impacts how they are absorbed, stored, and excreted by the body.

1. Fat-soluble vitamins: Vitamins A, D, E, and K are fat-soluble vitamins. They are absorbed with dietary fats and can be stored in the body’s fatty tissues for later use. Excess amounts of fat-soluble vitamins can accumulate and potentially lead to toxicity.

2. Water-soluble vitamins: B vitamins (including B1, B2, B3, B5, B6, B7, B9, and B12) and vitamin C are water-soluble vitamins. They are not stored in large amounts in the body and are excreted through urine. Regular intake of water-soluble vitamins is necessary as they are not stored for extended periods.

Functions of different vitamins

Each vitamin plays a unique role in supporting various bodily functions. Some key functions of different vitamins include:

1. Vitamin A: Essential for vision, immune function, and cell growth and differentiation.

2. Vitamin D: Plays a crucial role in calcium absorption, bone health, and immune function.

3. Vitamin E: Known for its antioxidant properties, it protects cells from oxidative damage and supports immune function.

4. Vitamin K: Required for normal blood clotting and bone health.

5. B vitamins: The B vitamins have various functions, including energy production, nerve function, red blood cell formation, and DNA synthesis.

6. Vitamin C: Known for its antioxidant properties, vitamin C is vital for collagen synthesis, immune function, and iron absorption.

Sources of vitamins

Vitamins can be obtained through a balanced diet that includes a variety of nutrient-dense foods. Some sources of vitamins include:

1. Vitamin A: Found in foods like liver, dairy products, fish, and fruits and vegetables rich in beta-carotene, such as carrots, spinach, and sweet potatoes.

2. Vitamin D: The primary source is sunlight, but it can also be found in fatty fish, fortified dairy products, and some mushrooms.

3. Vitamin E: Found in vegetable oils, nuts, seeds, and leafy green vegetables.

4. Vitamin K: Sources include leafy green vegetables, broccoli, Brussels sprouts, and some vegetable oils.

5. B vitamins: Found in whole grains, meat, poultry, fish, dairy products, and leafy green vegetables.

6. Vitamin C: Abundant in fruits and vegetables, particularly citrus fruits, strawberries, bell peppers, and broccoli.
