We created our Fish Oil as a do-it-all supplement for your dog or cat! It all starts by supporting a healthy skin and coat. But the benefits don’t stop there. Fish oil is also known to promote immune function, cardiovascular health and joint strength. Even better, Fera’s Fish Oil contains the highest amounts of EPA and DHA Omega-3 essential fatty acids per teaspoon compared to other leading brands, making it the go-to fish oil for your pet. No additives, no fillers and no toxins!

Made from sustainably wild-caught Icelandic sardines, anchovies, herring, and mackerel, our Fish Oil is formulated with the highest concentration of EPA & DHA Omega-3 fatty acids, which are essential to develop and function optimally in every state of a pet’s life.

Fish oil needs vitamin E to be processed by the body, so we include this natural antioxidant in our formula using a non-GMO, soy-free source derived from sunflowers.

Skin + Coat: Helps achieve a soft, shiny, and healthy coat.

Musculoskeletal: Nutritional support for joint strength and flexibility.

The best catch 🐟
We’ve been using the fish oil for over a week now, and when I tell you the girls are OBSESSED with it, I truly mean it. Not only do I feel good about giving them something that has so many health benefits, but I feel good knowing the ingredients used are wild caught, non GMO, and sustainable, not to mention their coats are already looking more shiny and healthy overall!

We were excited to try this fish oil to give our cats some added benefits to their diet. I was a little worried about them being picky but they lapped it up! Safe to say we will have no problem going through this bottle.
