What is Milk Thistle Extract?
Milk thistle extract, also known as silymarin, is a safe and beneficial supplement for dogs, particularly those with liver issues or who may be taking medications that could harm their liver. It’s a powerful antioxidant that protects liver cells and can support the liver’s ability to detoxify, according to Dr. Loudon.

Manufacturing Process
Milk thistle extract is produced through a series of steps to ensure the preservation of its active compounds:
1. Seed Preparation: Milk thistle seeds are cleaned, dried, and ground into a fine powder.
2. Extraction: Common methods include solvent extraction using ethanol or acetone, supercritical fluid extraction with carbon dioxide, and ultrasonic-assisted extraction. Each method aims to efficiently isolate silymarin from the seed material.
3. Purification: The crude extract undergoes purification processes such as filtration and concentration to remove impurities and concentrate the silymarin content.
4. Drying: Techniques like freeze-drying or evaporation under reduced pressure are employed to obtain a stable, dry extract while preserving the integrity of silymarin.
5. Quality Control: The final product is tested for silymarin content, antioxidant activity, and contaminants to ensure it meets quality standards.
