They play a crucial role in various bodily functions, including metabolism, [immunity](https://www.mindstick.com/blog/300473/improve-your-immunity-with-herbs-and-supplements), cellular processes, and the [maintenance](https://www.mindstick.com/articles/333912/maintenance-made-simple-how-online-tools-enhance-property-management) of healthy tissues and organs. While our bodies can synthesize some vitamins, many must be obtained from our diet or through supplementation. ![What are vitamins](https://answers.mindstick.com/QuestionAnswer/6b0966d8-2095-4258-a05e-de5268570f94/images/a530b92a-8b16-48d4-aa01-8befa9a07d35.jpeg) There are two main categories of vitamins: **water-soluble vitamins** and **fat-soluble vitamins.** Vitamin C and the eight B vitamins, namely thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folate (B9), and [cobalamin (B12)](https://www.mindstick.com/blog/300660/why-is-vitamin-b12-so-important), belong to the group of **water-soluble vitamins**. Water-soluble vitamins are not stored in large amounts in the body, and any excess is typically excreted through urine. As a result, regular consumption of these vitamins is necessary. Vitamins A, D, E, and K are classified as **fat-soluble vitamins**. These vitamins are absorbed along with dietary fats and can be stored in the body's fat tissues and liver. Unlike water-soluble vitamins, fat-soluble vitamins can be stored for longer periods, and excessive intake may lead to toxicity. Hence, it is crucial to consume them in proper quantities. ## Every vitamin has a distinct function within the body: - Vitamin A: Essential for vision, immune function, and the health of skin and mucous membranes. - Vitamin D: Crucial for calcium absorption and bone health. It also contributes to immune function. - Vitamin E: Functions as an antioxidant, safeguarding cells [against](https://www.mindstick.com/news/2526/resolution-against-anti-satellite-tests-adopted-by-un-to-reduce-space-debris) damage. It also supports immune function and helps with blood clotting. - Vitamin K: Required for blood clotting and bone health. - [Vitamin C](https://yourviews.mindstick.com/view/83274/is-it-safe-to-take-vitamin-c-when-pregnant): Important for [collagen](https://www.mindstick.com/articles/310654/can-collagen-really-help-with-joint-pain) synthesis, wound healing, immune function, and as an antioxidant. - B vitamins: Involved in various metabolic processes, energy [production](https://www.mindstick.com/news/2276/by-the-end-of-2023-tesla-cybertruck-mass-production-will-begin), and the maintenance of healthy skin, hair, and nervous system. **A well-balanced diet** comprising diverse fruits, vegetables, whole grains, lean proteins, and healthy fats can provide the necessary vitamins. However, certain individuals, such as pregnant women, older adults, strict vegetarians, or those with specific medical conditions, may require vitamin supplements or fortified foods to meet their nutritional needs. **While vitamins are vital for our health**, it is important to note that excessive intake of certain vitamins can have adverse effects. Therefore, it is generally recommended to obtain vitamins from natural food [sources](https://www.mindstick.com/articles/44491/how-to-evaluate-credibility-of-internet-sources) rather than relying solely on supplements unless medically advised. --- Original Source: https://answers.mindstick.com/qa/99660/what-are-vitamins Copyright © MindStick Software Pvt.
