What it is

Milk thistle is a flowering plant native to the Mediterranean region. Its seeds contain a compound called silymarin, which is extracted for use in supplements and sometimes in food products. The extraction process typically involves grinding the seeds and using solvents to isolate the active compounds.

Why it's used

Milk thistle is most often added to teas and beverages, where it is valued for its perceived health benefits rather than a specific functional role like sweetening or preserving. It is sometimes included in energy drinks or other functional foods marketed for wellness.

Health notes

Milk thistle extract, primarily silymarin, is generally recognized as safe (GRAS) by the FDA for use as a dietary ingredient. It is not typically regulated as a food additive. Regulatory bodies like EFSA have evaluated silymarin, but no specific ADI has been set. Research into milk thistle's health effects is ongoing, with some studies suggesting potential benefits for liver health, while others show mixed results. It is not approved by the FDA to treat, cure, or prevent any disease.

Allergen info

Milk thistle is not derived from any of the nine FDA major allergens. It does not contain gluten.
