Questions & Answers

7 Customer Questions

If it doesn't need refrigerated, what is the shelf life once opened? Is it recommended that you discard the product after so many days/months like other fish oils?
Answer by ChewyJun 19, 2022
This supplement has a shelf life of 3 years once opened. It is recommended to store the formula in a cool dark place. Refrigeration is recommended if home or cabinets are too warm.

What specific types of marine animals/fish are in the "Marine Lipid Concentrate" ingredient? My cat has food allergies, including to some species of fish. Thank you!
Answer by ChewySep 10, 2020
The marine lipid concentrate in this supplement is made up of anchovies and sardines. These small fish come from the pristine waters of Norway.

What is the marine lipid
Answer by ChewyJan 06, 2021
This supplement contains 3000 milligrams of Marine Lipid Concentrate per teaspoon.

Can this be used for my 13 week old lab puppy? If not is the an equivalent for her? At what age can you start this supplement?
Answer by ChewyDec 16, 2020
The Ultra EFA can be safely given to puppies once they have reached 6 months of age. A good starting dose is ¼ teaspoon a day divided between feedings. Start with a very small amount to avoid any sort of gastric distress.

Highly Recommend

Vet recommended for my dog's Dermatitis in combination with Apoquel. With consistent use, we've been able to see improvement in her coat not being as dry/coarse and decrease in itching to the point of rarely taking the Apoquel now! Highly recommend.

Keep this Product Chewy

My holistic vet recommended this for my older blue tick coon hound rescue dog, since giving this to her combined with her home feeding and also combined with Call of the Wild(vitamin powder supplements for dogs/cats)she looks fantastic, there is not a day that goes by where a few people don't comment, in NYC, how gorgeous this dog is and it's mostly the skin/coat, she also lost 14 pounds and does not have epilepsy as they thought, she is on the right diet. I hope she lives past 15, this is the goal. thanks chewy!

The BEST Omega Oil (and then some!)

We've tried many omega supplements (liquids and chews) for our Yorkies over the years, to improve their overall health and coat quality, and to reduce their dry, itchy skin. This formula has given us by far the BEST and QUICKEST results, especially in enhancing the luster and softness of their coats. Our vet is always so impressed with their overall health! It's expensive for fish oil, but we chose this brand because of its potency, and because it also includes Vitamin E (supposedly necessary with Omegas), Biotin, Zinc, and other ingredients beneficial to skin. PLUS, it settles just fine with my one's highly sensitive tummy. It does smell more of Rosemary than fish oil -- some dogs might not be fans of the taste, but mine sure are! In fact, instead of adding it to their food, I just measure it out at mealtime and they lick it enthusiastically off the spoon. Please continue to carry this product, Chewy! It's made a world of difference for my pups' skin and coats.

My dogs and cat love the taste!!

I put these vitamins in with the dry food for my dogs, and wet food for my cat. My dogs eat their food immediately, loving the taste. My cat, too. Very easy to use.

Perfect for my Ragdoll

I bought this supplement after reading about it on a ragdoll cat website. My ragdoll sheds like crazy and within a day of using this supplement, there is substantially less hair around the house! I am actually shocked at how well this works. My cat also didn't mind the taste or smell. Great product!

Hit or miss

It has a distinct rosemary scent that some of my cats won’t touch.

Ultra EFA Supplement

According to my vet, for arthritis the best results (& most researched) seem to come from the use of Omega 3 essential fatty acids. She recommended this particular supplement & my cats seem ok with it added to their wet food.
