What is Sterol?

Sterols are a subgroup of steroids that occur naturally in plants and animals. They are essential components of cell membranes and play a role in various biological functions. Plant sterols, also known as phytosterols, are often added to foods to help reduce cholesterol levels. Animal-derived sterols, or zoosterols, include cholesterol. Due to their differing sources, sterols can be suitable for vegans if derived from plants.
