NOW Pet Health, Cardiovascular Support Supplement, Formulated for Cats & Dogs, NASC Certified, Powder, 4.5-Ounce

Bought this as a supplement because my dog has very rigid dietary needs. I make my own dog food and know that my pup may not be getting all of the nutrients he needs, so I Did a lot of research and found this brand the best quality and suited our needs. I found it easier to premeasure the amounts (along with another powder he needs) into individual daily cups, then mix it into a “gravy” before adding the solid chicken and this works perfectly. My finicky eater absolutely loves it!

I was looking for something with L-carnitine and CoQ10 because I read that they help cats that are hyperthyroid. I tried another brand's “dog & cats” capsules that were too big for cats and the cat wouldn't go near the food even with a speckle of that in the food. The other ingredients in this supplement by NOW are a plus for my 15-year-old senior cat. This one mixed with water, makes a very nice broth which add to my cat's wet food. She ate her food as usual which is a big deal! It is too soon to tell about results, but I trust NOW for my own supplements for years, so I am sure the ingredients are good quality and will have the best chance to be helpful. [Update] It has been at least two weeks, she loves the taste! If I don't give it to her, I will definitely hear about it! It makes it easy to mix in other things like Cosequin, fiber, and Miralax. I wish NOW would make a standalone broth without the supplement ingredients, so I can give it to her more liberally. I cannot attribute to this supplement 100% due to other changes, but she is doing great, and I am confident this supplement is a key contributor! She looks more lucid, more independent, has better appetite (added a bit of weight that she needed), and she even gets the zoomies every once in a while.

My dog benefited from taking. Would buy again

I purchased this Taurine supplement for my English Setter after reading that setters sometimes can suffer from a condition called Dialated Cardiomyopathy, a heart condition resulting from low Taurine aggravated by extreme exercise/conditions that hunting dogs sometimes experience. The powder is easily mixed with the dog's food and they seem to find it very palatable. I did read that my dog food has some Taurine as an ingredient already so I did go for a lowered dose of the supplement, which I was adding Just in Case anyway.

I didn't know what this was supposed to look like when I got it. I bought this in April and it's yellowish brown and in small clumps, and only lately did I try to smell it and it stunk. I never used any wet spoon to scoop it out from the bottle. It has that moisture absorbing packet still. It's the stinch that made me wonder if this is supposed to be like this. My poor dogs... I bought this to help prolong my dogs' lives. This could've made them sick/sicker and killed them instead. UPDATE (July 2026): The specific batch number on this rotten, clumpy bottle is Lot #3435964, Code #0416, Best By 11/01/2027. Please check your bottles immediately to protect your pets

Yummy! my cat loves the flavor of NOW Cardiovascular Support in her wet food! I suspect the reason it got lumpy over time must have been airborne bacteria attacking the broth. When I got a fresh bottle I put some in an airtight spice jar and kept it in the fridge. The rest is kept airtight in the freezer. Maybe I don't need to freeze. Been using it from the fridge daily for 5 months and the spice jar still pours the powder smoothly, no lumps! P.S. Under the airtight lid of a spice jar is a removable cap for sprinkling. Some caps have an opening for pouring into a measuring spoon. The kind that pours is handy.

I've been using this supplement for around 4 months. It's become very hard like a rock. It also has a very distinct rotten fish smell? I have no idea why? Is this supplement supposed to be refrigerating and why is it hardening like a fossil??????

I bought one bottle. It became unusable. It clumped up and became a rock. For my second bottle I parsed it into 2 oz Nalgene screw top containers and packed the 5 or 5 bottles in a silicon bag with silica gel. It works.

Shocking. Goes rock hard and goes “off”. Have stuck with it and tried everything over several buys, and finally managed to make the latest purchase last a bit longer by decanting into an airtight tub, but it still goes hard in the end and goes thicker with the most disgusting smell. I think the “chicken broth” contaminates it after a while. Yuk.
