What are vitamins?
Vitamins were discovered in the 19th century, as a group of substances that could cure deficiency diseases. Accordingly, these substances were named with the prefix “vita,” meaning “life.” Scientifically speaking, vitamins are complex organic compounds that the body requires for various vital functions. For example, they control or support certain metabolic processes.
However, humans cannot synthesize (produce) vitamins themselves and therefore have to ingest them with their food – either as chemically complete vitamins or as provitamins. Provitamins are precursors that are converted into the active form in the body. By the way, the only exception to this is vitamin D, which the body can actually produce in the skin as long as there is enough sunlight.
