Heart and vascular supplement. Promotes canine cardiovascular and circulatory function

maxxicardio is specifically designed to naturally promote cardiovascular function in dogs and to help maintain healthy heart muscle strength.

The carefully selected mix of amino acids, minerals and vitamins support and help maintain good canine heart health. Each ingredient has its own important role and together they work synergistically to support and maintain cardiovascular and circulatory health in dogs.

maxxicardio supports normal blood flow circulation, facilitates oxygen utilization and can help to strengthen weak heart rate and regulate erratic or irregular heartbeat (heart murmur).

Made in the USA in GMP and NASC (National Animal Supplement Council) certified manufacturing facility using NON-GMO pharmaceutical Human Grade ingredients, tested for purity and potency.

Suitable for all dog breeds.

Halting progression of my dogs heart disease

My little dog was diagnosed with early stage degenerative mitral valve disease in February 2025. No treatment was warranted but I immediately ordered maxxiCardio (we already use maxxiSAME for his liver due to epilepsy with great results). Fast forward 6 months his taurine levels are up from 60 to 134umol/L and several of his measurements in one of his heart chambers has decreased slightly on his most recent scan. All I was hoping was for no progression but to see no progression plus some improvement is amazing. He was asymptomatic at presentation (heart murmur picked up at routine check is checked every 3 months for medication) and he remains asymptomatic now and continues to lead an active lifestyle including agility. We cannot thank MaxxiPet enough for their amazing products. I recommend them to everyone I can.

Very good experience of maxxipaws

I just found out couple of weeks ago that my wee dog has heart murmur. The vet says it is mild and he does not require medication for now. He will just need regular heart check-ups in the future. When I saw that maxxipaws has heart support I decided to give it a go as I have very good experience of maxxipaws products. It’s early days as I just received the bottle but I’m happy to report that he happily accepts it mixed with his food. I will update after his next check-up later this year.

He has more energy now

One of my cats was born with heart murmur so he has annual check up and no problem. He is now 12 and still doing well but the vet said that now might be a good time to start him on some L-Carnitine as it is frequently recommended for cats with heart problems. I found maxxicardio online and liked that it had more ingredients that support the heart. The vet approved the list of ingredients so I have been giving this to him now for few months and it is going very well. He likes the taste and even though he was doing fine beforehand, I feel he has more energy now. Good stuff.

Very happy customer

My little girl, 10 years old / 10 kg, was diagnosed with mild heart problem few months ago. The vet didn’t want to put her on medication, he just wanted to monitor her. However she was struggling with the stairs and breathing heavily so I asked him about supplements and he recommended maxxicardio or something similar. I picked maxxicardio as I liked how transparent everything was, it is easy to find all the ingredients and they also provide detailed information about each ingredient on their website. I liked that very much. I’m very happy that I did as I saw almost immediate results. Her breathing is back to normal and the stairs are no problem for her now. Her energy level has improved so much, I just now realize how much her heart problem was really affecting her. She is now playing and running and jumping around like much younger dog. I expect to keep her on maxxicardio for the rest of her life. It also lasts her for ages, I gave her 1 scoop for the first few weeks but she now gets around ¾ of a scoop so needs less the 2 tubs a year if my calculations are correct! That’s a bargain in my books. Very happy customer.

Helps to keep him in top form

My dog does flyball and maxxicardio helps to keep him in top form and keep his spot in a winning team. Necessary part of his routine now.

Best combination of ingredients

My elderly rescue cat was recently diagnosed with heart murmur. Fortunately her condition is relatively mild and because of her age the vet just wants to monitor her closely for now. He recommended using natural heart supplement for her and then check her condition again in 6 months’ time. I did a lot of online research about the ingredients. It has to be said that here are not many heart supplements available just for cats. Of those I found maxxicardio had by far the best combination of ingredients. She can be fussy but she does not mind this powder added to her food. I don´t expect any miracles but I hope it will keep her condition from worsening. Actually I have the feeling that this may already be helping she seems more energetic but we will know for sure when she has her next vet check in few months’ time.

Energy level is back to what it was

My girl is Cavalier King Charles Spaniel and she has Grade 3 MVD murmur and prolapsed valve. I have researched carefully which natural ingredients offer best heart support. Most products on the market contain only one of those ingredients so I was very happy when I came across maxxicardio with this great range of heart supporting ingredients. My fussy girl happily accepts this added to her food which is always a bonus! She has been on maxxicardio for couple of months now and her energy level is back to what it was few years ago. For once looking forward to her next vet appointment!

My cat is more energetic

My cat is more energetic and playful since I started giving her maxxicardio. She does seem to like it, or at least not affected her appetite! She is a Maine Coon and they are at risk of getting HCM so my vet recommended giving her some taurine as a preventative. I found maxxicardio by chance on Facebook and I really liked that it had more ingredients than taurine so I decided to give it a try and I am very happy I did! I will continue to use maxxicardio for my precious girl.
