What is a vitamin? A vitamin is an organic compound that the human body requires in small amounts to carry out essential biochemical functions, such as metabolism, immune support, and cellular repair. Unlike other nutrients, vitamins cannot be synthesized by the body and must be obtained through diet or supplementation. This reliance on external sources highlights their crucial role in maintaining health and well-being.

Many vitamins have been found, with vitamin D being a historical misinterpretation. Deficiencies in vitamins do not necessarily equate to imminent death, but there will be some health repercussions. Below is a list of vitamins that you can follow once I add some information, which will take some time. Let’s first have a look at a very crude classification of vitamins into fat- and water-soluble ones.

Vitamin D, in fact a hormone, is said to be soluble in fat. Therefore, it has been cautioned, that too large an intake or production of D3 or more precisely Cholecalciferol can be dangerous since it could be stored in fat. Solubility is not that easy, especially when considering biological systems. First of, anything is soluble in anything to a varying degree. When saying D3 is fat soluble, we also need to consider that there are three different molecules that we mean when we say D3 (see vitamin D for a disambiguation).
