Which vitamins cannot be stored by the body and must be consumed regularly?

The vitamins that cannot be stored by the body and must be consumed regularly are the water-soluble vitamins. These include vitamins such as B-complex vitamins and vitamin C. Unlike fat-soluble vitamins, which are stored in the body's fatty tissues and liver, water-soluble vitamins dissolve in water and are not stored to a significant extent. Instead, any excess is typically excreted through urine. This means that a consistent intake of water-soluble vitamins is essential to maintain proper bodily functions and prevent deficiencies.

Fat-soluble vitamins, in contrast, can be stored in the body and do not require daily consumption. Minerals, while essential nutrients, are not classified as vitamins and have different storage and absorption characteristics. Calories refer to energy content rather than vitamins, making this choice unrelated to the question about vitamin storage.
