Silybon Syrup contains silymarin, which is an extract derived from the milk thistle plant. It is a herbal medicine used primarily to support liver health and protect liver cells. In general, silymarin itself is plant-based and does not come from animal sources. Most formulations of Silybon Syrup are considered vegetarian as the active ingredient is derived from a plant. However, the final product may also contain other inactive ingredients such as preservatives, flavouring agents, or stabilisers, which can vary depending on the manufacturer. Because of this, the vegetarian or non-vegetarian status can sometimes depend on the specific brand formulation and how it is processed. If you strictly follow a vegetarian or vegan diet for personal or religious reasons, it is best to check the product label or confirm with the manufacturer or pharmacist.
