Milk thistle, also known by its botanical name Silybum marianum, is a powerful herb used for centuries to support the liver. It is also gaining popularity in animal supplements, particularly in formulas focused on detox, recovery, or long-term medication. The active ingredient silymarin, a complex of antioxidant flavonolignans, is known for its protective and stabilizing effect on liver cells. However, not every form is suitable for every supplement, and its use varies by animal species. In this article, we delve deeper into the properties of milk thistle, the various extract forms, and how pet food brands or supplement developers can make a conscious choice when using this versatile ingredient.
Dogs and cats
Silybum marianum is often added to liver and detox formulas. This applies in situations where the animal is on medication, recovering, or with chronic conditions such as atopy or allergies.
Common combinations include with:
Artichoke (Cynara)
Curcumin
Taurine or methionine (for liver metabolism)
Horses
Milk thistle can provide support for performance horses or horses with elevated liver function. It is also often used during the transition to a new diet or for metabolic problems.
Milk thistle is available as:
Dry extract (standardized for silymarin content)
Tincture (alcoholic extract for liquid applications)
Powder (ground seed, less concentrated)
At Nutriliq, we primarily use standardized extracts (e.g., 80% silymarin) because they provide predictable and reproducible effects in supplements.
Dosage is important: for visible effects, the silymarin content must be sufficient
Combination with other liver-active substances can work synergistically
Application form: Milk thistle is suitable for powders, chews, liquids and pastes, provided the correct extract is chosen.
Stability: Standardized extracts are relatively stable, but sensitive to high temperatures
At Nutriliq, we incorporate Silybum marianum into customized liver and detox supplements. Consider combining it with:
Antioxidants(vitamin C, E, selenium)
Herbs such as dandelion, turmeric or milk thistle
Prebiotics for the gut-liver axis
We develop supplements in the form of soft chews, powders, pastes, liquids or gummies, depending on your target audience, dosage and marketing objective.
