Silybin Phytosome (Siliphos® from Milk Thistle)

PRIMARY FUNCTION

Advanced liver support supplement providing potent antioxidant, anti-inflammatory, and hepatoprotective effects in dogs and cats.

HOW IT SUPPORTS PET HEALTH

Silybin is the most active compound in milk thistle extract (silymarin), known for protecting liver cells, supporting liver regeneration, and neutralizing free radicals. Silybin phytosome (Siliphos®) is a patented complex of silybin and phosphatidylcholine, greatly enhancing the absorption and bioavailability of silybin compared to standard milk thistle extracts. This improved delivery means Siliphos® can deliver more consistent and effective support for liver health in pets with liver disease, toxin exposure, or those undergoing drug therapies that stress the liver.

FUNCTIONAL OVERVIEW

– **Antioxidant Defense:** Silybin scavenges free radicals and supports the liver’s own antioxidant systems, helping to reduce oxidative stress and cellular injury.
– **Anti-inflammatory and Antifibrotic:** Silybin reduces inflammation and helps limit fibrosis (scarring) in the liver, supporting long-term liver function.
– **Enhanced Bioavailability:** Siliphos® phytosome technology increases silybin absorption several-fold compared to standard silymarin, resulting in higher blood levels and greater efficacy.
– **Liver Cell Regeneration:** Silybin promotes repair and regeneration of liver cells, aiding recovery from liver disease or toxin exposure.
– **Protection During Chemotherapy:** Silybin may help protect liver cells and reduce side effects in pets receiving chemotherapy.

COMMON VETERINARY USES

Primary Benefits for Pets
  • Liver Protection: Shields liver cells from toxins, drugs, and oxidative stress.
  • Supports Recovery: Aids in liver regeneration after injury, disease, or toxin exposure.
  • Adjunct in Chronic Liver Disease: May help slow progression and improve quality of life in chronic liver conditions.
  • Potential Chemotherapy Support: May reduce liver-related side effects of cancer treatments.
Veterinary Use Cases
  • Management of liver disease (hepatitis, cirrhosis, toxin-induced injury.
  • Support for pets on long-term medications that affect liver function.
  • Adjunctive therapy for pets recovering from toxin exposure (e.g., mushrooms, aflatoxins).
CONTRAINDICATIONS & SENSITIVITIES

Silybin phytosome (Siliphos®) is generally well tolerated at recommended doses. Mild side effects, such as gastrointestinal upset or mild allergic reactions, are rare and typically associated with very high doses. Always consult your veterinarian for appropriate dosing and monitoring, especially in pets with severe liver compromise or those on multiple medications.
