Reviews highlight strong mood and cardiovascular benefits of omega-3 EPA, but quality concerns including contaminants and inconsistency temper enthusiasm.
Thorne Vet Liver Support Formula (formerly Hepagen) is a veterinary-grade nutritional supplement formulated to support healthy liver function in dogs and cats. It combines liver-supportive compounds including milk thistle extract (silymarin), N-acetyl cysteine, and additional antioxidant cofactors to support hepatic detoxification pathways and cellular integrity in companion animals.
Why It's Worth Considering: Formulated by Thorne Vet, a practitioner-trusted brand known for rigorous quality standards, this product uses researched ingredient forms and dosing relevant to veterinary clinical practice.
| Feature | Fish Oil (this) | Krill Oil | Algal Oil | Cod Liver Oil |
|---|---|---|---|---|
| EPA+DHA Content | High (concentrated) | Moderate | Moderate-High | Moderate + Vit A/D |
| Absorption | Good (triglyceride form) | Excellent (phospholipid) | Good | Good + fat-soluble vitamins |
| Best For | Therapeutic dose, heart/brain | General wellness | Vegan option | Vitamin A+D + omega-3 |
| Sustainability | Varies by brand | Sustainable harvest | Most sustainable | Traditional, sustainable |
| Burp Factor | Low (if enteric coated) | Very low | None | Moderate |
For general health, 1-2g of combined EPA+DHA daily. For therapeutic use (triglycerides, inflammation, mood), 2-4g combined EPA+DHA. Check the label for EPA+DHA content per serving — many fish oils have only 300mg per 1000mg capsule, requiring 6-8 capsules for a therapeutic dose. Concentrated formulas provide 600-900mg per capsule.
EPA (eicosapentaenoic acid) is primarily anti-inflammatory — best for joint pain, cardiovascular health, and mood disorders. DHA (docosahexaenoic acid) is structural — it comprises 40% of brain polyunsaturated fats and is critical for cognitive function, eye health, and fetal development. Most people benefit from both; higher EPA for inflammation, higher DHA for brain health.
Low-quality fish oil can cause fishy aftertaste and burping. Solutions: take with food, choose enteric-coated capsules, refrigerate the bottle (slows breakdown), or use a concentrated triglyceride-form fish oil (higher quality = less burping). If you still experience burps, the oil may be oxidized — check the expiration date and smell the capsule.
Krill oil has better absorption per gram (phospholipid form) and contains astaxanthin (antioxidant), but it's significantly more expensive per mg of EPA+DHA. For therapeutic doses (2-4g EPA+DHA), fish oil is more practical and cost-effective. Krill oil is a good choice for general wellness at maintenance doses.
Fish oil has mild blood-thinning properties. If you're taking warfarin, aspirin, or other anticoagulants, consult your physician before starting high-dose omega-3. At standard doses (1-2g), the risk is low, but your INR may need monitoring. Stop fish oil 1-2 weeks before scheduled surgery.
Look for: third-party tested for heavy metals and oxidation (IFOS 5-star rated), triglyceride form (not ethyl ester), high EPA+DHA per capsule (600mg+ combined), and molecular distillation for purity. The Gabriel Score evaluates all of these quality signals automatically.
