Vitamin D is a substance essential to life, found in certain foods and produced by the body when cholesterol in the skin reacts to ultraviolet rays from the sun. Although it is classified as a vitamin, it functions more like a hormone in the body.Toxicity risk due to its chemical properties
The non-water-soluble nature of vitamin D means it can build up in the body over time. When consumed in excessive amounts, it can become toxic, leading to serious health issues such as those experienced by the victims in the Balearic Islands.
