No issues with flavor.

My cat has no problems with it being added to her food. I’ve tried a couple of supplements before that she would NOT eat at all, even if it was mixed in with wet food. With this powder, she has no issues.

Keeping my cat healthy!

I bought this for my 12 yr old cat who is showing his age. He seems to like the taste if I sprinkle it on the first small bite of wet food. Assuming it it helping his heart health.

Now Cardiovascular Support

I am not sure if this really has helped my cat but I wanted to safeguard her heart due to the beginning signs of cardiomyopathy. The one thing about the product was it had to be ground into more of a fine powder to mix better in her wet food. Other than that, she didn't seem to mind taking it.

Heart support

My dog was diagnosed with a heart murmur. I sprinkle this on her food to give her additional support and she has no problem eating it.

I trust the brand NOW

Although, it’s too soon to tell if this supplement is working, I am hopeful. My dog has a slightly enlarged heart. My vet didn’t seem overly concerned with it. However, due to the recent hype regarding DCM (dilated cardiomyopathy) surrounding canine dietary deficiencies in kibbles, I decided to supplement. My dog gets limited grains in his diet due to eliminating unnecessary carbohydrates. The issue surrounding DCM, based on recent studies, seems to be the lack of taurine in dog’s being fed a grain-free diet, more particularly dry kibble diets. He doesn’t eat kibble but studies of this are still new and evolving so I want to cover my bases when it comes to his health. This supplement has taurine along with other heart-healthy nutrients to hopefully replenish anything that his system is lacking. I prefer to use food to alleviate issues as I follow the “food is medicine” philosophy. However, he’s so finicky with his taurine packed organ meats that it’s hard to measure the taurine that his system is absorbing via food. In several months, we will do another radiograph and see if his heart is shrinking like the Grinch... if so, I’ll be able to say it is because of this supplement. Taste-wise, he’s not too incredibly picky overall about powders and he eats this right up. I do wish this came in a better container as far as ease of dispensing. I emptied it into a wider tub and use a scoop I had in the junk drawer to measure out his tablespoon daily.

So glad they made this product

My dog was diagnosed with an enlarged heart and the beginning of congestive heart failure. My Vet suggested that she start taking this and I already notice her breathing improved. She is also starting to take longer walks. I measure the correct amount and she loves it. I don’t even need to mix with her food.
