Omega-3 reviews are broadly positive on health outcomes—mood, heart, brain—but safety concerns about contaminants and certification credibility temper enthusiasm.
Guaranteed analysis per 1 soft gel (1,000 mg fish oil): crude fat (min.) 67%; moisture (max.) 4%; eicosapentaenoic acid (EPA) (min.) 11%; docosahexaenoic acid (DHA) (min.) 7%; total omega-3 fatty acids (min.) 22%. Includes 155 mg EPA, 100 mg DHA, and 320 mg total omega-3s in triglyceride form. Calorie content (calculated): ME 7,180 kcal/kg, 10 kcal/soft gel.
Ingredients: fish oil (from anchovies, sardines, mackerel, and herring), gelatin, water, glycerin, d-alpha tocopherol (a preservative).
Add to your dog's food, or serve by itself, daily. 10–19 lb: 1 soft gel; 20–39 lb: 2; 40–59 lb: 3; 60–79 lb: 4; 80–110 lb: 5; 111–130 lb: 6. For dogs 2–10 lb, use the manufacturer's smaller-dog product. For dogs over 130 lb, consult your veterinarian. Do not exceed the suggested daily use without consulting your veterinarian.
For animal use only. Keep out of reach of children and pets. Store in a cool, dry place away from sunlight. Do not use if the tamper-evident seal is broken or missing. Consult your veterinarian before use if your dog has a known medical condition or takes medication. In case of overconsumption, consult your veterinarian immediately.

Nordic Naturals Omega-3 Pet Soft Gels deliver concentrated EPA and DHA from purified fish oil in a soft gel format designed specifically for pets. These omega-3 fatty acids support healthy skin and coat, joint mobility, and cognitive function in dogs and cats. Formulated for pet owners seeking a straightforward, triglyceride-form fish oil for their animals.
Why It's Worth Considering: Nordic Naturals uses a triglyceride molecular form, which research suggests absorbs more readily than ethyl ester alternatives, and third-party tests for purity and oxidation levels.

| 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.
