Milk Thistle Extract

Milk thistle extract comes from the seeds of the milk thistle plant (Silybum marianum), a flowering herb native to the Mediterranean region. The seeds are typically dried, ground, and then extracted using solvents or other methods to isolate beneficial compounds, primarily silymarin.

Milk thistle extract is often added to beverages and supplements for its purported health benefits, particularly related to liver health. It is not typically used for its functional properties as a sweetener, emulsifier, or preservative in the same way as many other food additives.

Milk thistle extract is generally recognized as safe (GRAS) by the FDA for use in certain food categories, particularly as a dietary ingredient in beverages. Regulatory bodies like the European Food Safety Authority (EFSA) have evaluated silymarin, the active compound in milk thistle, but have not established specific health claims for its use in foods. Research into milk thistle's effects is ongoing, with some studies suggesting potential benefits for liver health, while others show mixed results or no significant impact.
