These vitamins are not stored in the body and are excreted through urine, requiring a continuous supply through diet. On the other hand, fat-soluble vitamins, which include vitamins A, D, E, and K, are stored in the liver and fatty tissues, allowing the body to draw upon them as needed.

The importance of vitamins cannot be overstated, as they are crucial for maintaining various bodily functions. For instance, vitamin D is essential for bone health, facilitating calcium absorption, while vitamin A contributes to vision and immune function. B-complex vitamins are integral for energy production and the synthesis of neurotransmitters, which are vital for brain health. Additionally, vitamin C acts as an antioxidant, combating free radicals and supporting the immune system.

A well-balanced diet rich in vitamins is key to preventing deficiencies that can lead to serious health issues. For example, a lack of vitamin B12 can result in anemia, while insufficient vitamin C can lead to scurvy. Therefore, understanding the different types of vitamins and their general benefits is crucial for optimal health and well-being.
