Did you know vitamin D is technically a secosteroid hormone precursor, not an acid? This article addresses the common question, "Which acid is known as vitamin D?" by clarifying the compound's true nature and explaining the metabolic pathways involved.

Contrary to a common misconception, vitamin D is not an acid but a secosteroid hormone, derived from cholesterol. The confusion likely stems from a metabolic breakdown product called calcitroic acid, which is produced to facilitate the vitamin's excretion from the body.

Unlike many vitamins, the body does not easily excrete vitamin D through urine, a critical fact for understanding its metabolism. So, **does vitamin D get excreted in urine**? The process is far more complex than simple urination due to its fat-soluble nature.
