Fish Oil Supplement
Verified May 26, 2026
This is a concentrated liquid fish oil supplement for dogs and cats, providing very high levels of the omega-3 fatty acids EPA and DHA. It uses oil from wild-caught sardines, anchovies, herring, mackerel, and pollock, with added vitamin E from sunflower as an antioxidant. It’s designed to be added to regular food to boost omega-3 intake for skin, coat, joint, heart, brain, and immune support.
Nutritionally, this is a high-quality, very concentrated omega-3 supplement suitable for most dogs and cats when used at appropriate doses. The use of multiple named, wild-caught fish species and clear EPA/DHA levels is excellent for owners who specifically want to increase marine omega-3s in their pet’s diet. As with any pure oil product, it’s important to account for the added calories and to introduce it gradually to avoid digestive upset.

KibbleLab Review
Strengths
- Clearly defined omega-3 content with high levels of EPA (17%, 700 mg/teaspoon) and DHA (10%, 400 mg/teaspoon), which is ideal for targeted omega-3 supplementation.
- Made from multiple named, wild-caught fish species (sardines, anchovies, herring, mackerel, pollock), which are naturally rich in marine omega-3s.
- Very simple ingredient list with no inactive ingredients besides the fish oils and sunflower-derived vitamin E, which is helpful for pets that need limited additives.
- Liquid format makes it easy to measure and mix into food, allowing precise dosing based on a pet’s size and needs.
Considerations
- This is almost entirely fat (about 99.9% crude fat), so the extra calories need to be considered, especially for overweight pets or those on strict calorie control.
- Because it’s derived from fish, it is not appropriate for pets with known fish allergies.
- Like all oils, it needs proper storage (refrigeration, use within a few months) to minimize oxidation and maintain quality, and oxidized oils can be less beneficial and may cause digestive upset if used too long.

Top 5 Ingredients Explained
01
Sardine
Sardine serves as a rich animal protein and palatability enhancer in pet food, supplying highly digestible protein, abundant omega‑3 fatty acids (EPA and DHA), B vitamins and vitamin D, and when included whole can provide calcium and phosphorus. They can benefit both dogs and cats by supporting skin and coat, joint and cardiac health, but owners should watch for high sodium in some canned products, potential fish allergies or digestive upset in sensitive animals, and choose sustainably sourced, low‑sodium options to minimize contaminant exposure.
02
Anchovy
Anchovy is a small oily fish commonly used in pet foods and treats as a high‑quality animal protein and palatant that also supplies concentrated omega‑3 fatty acids (EPA/DHA) and, when whole or rendered to meal, micronutrients such as calcium and selenium that support skin and coat, joint, heart and brain health in both dogs and cats. Considerations include variable sodium levels in canned or preserved forms, the (rare) possibility of fish allergy, and the importance of responsible sourcing and handling to minimize contaminants or histamine formation.
03
Herring
Herring is commonly used as a high-quality, palatable fish protein and oil source in dog and cat foods, supplying digestible protein along with beneficial long-chain omega-3s (EPA/DHA), vitamin D, B vitamins and trace minerals. It can support skin, coat and joint health, but may be an allergen for some pets and raw fish can contain thiaminase (typically destroyed by commercial cooking); owners should also consider fat content for pancreatitis-prone animals and look for responsibly sourced, low-contaminant products.
04
Mackerel
Mackerel is a fatty fish commonly used in pet foods as a high‑quality animal protein and a rich source of omega‑3 fatty acids (EPA and DHA), often added for flavor, palatability and healthy fats. Its omega‑3s support skin and coat condition, immune and joint health in dogs and cats, but owners should be aware of potential heavy‑metal accumulation, food sensitivities, and higher fat or sodium in some preparations, so choose properly processed, deboned sources from reputable suppliers.
05
Pollock
Pollock is a lean white fish commonly used in pet foods as an easily digestible animal protein that boosts palatability and supplies essential amino acids. It provides some omega‑3 fatty acids and is generally low in contaminants compared with larger predatory fish, but can be an allergen for sensitive animals and must be properly processed and balanced (e.g., for taurine in cat diets) and preserved to prevent rancidity.
