One in Ten Dogs Has a Heart That Is Not Getting What It Needs.\nEleven ingredients spanning amino acids, antioxidants, cardioprotective botanicals, and bioavailable minerals. Working across every dimension of what healthy cardiac function requires, every single day.\n\n✓ 11 Active Ingredients ✓ L-Carnitine and Taurine 140mg Each ✓ Vet-Formulated ✓ Non-GMO ✓ NASC Certified\n\n\n\n\nThe organ working hardest every single day\nThe heart beats over 100,000 times a day. It never rests, never gets a recovery period, never gets a break to rebuild. And heart disease in dogs develops the same way the heart works — quietly, without announcement.\nAccording to the American Veterinary Medical Association, one in ten dogs has less than optimal cardiovascular health. That number climbs significantly in certain breeds, in senior dogs, and in dogs carrying extra weight or managing other chronic conditions. Like so many conditions that affect aging dogs, heart disease compensates. It works harder to do less. By the time a heart murmur is detected or symptoms appear, the heart has often been under significant strain for a long time.\n\nHeart Health Formula was built to give the heart what it needs to keep working well. Whether the goal is supporting a dog already managing cardiovascular disease, protecting a breed with known cardiac predisposition, or investing in the long-term health of the organ that everything else depends on, this is the formula we trust.\n\n\n\n\nWhy cardiac muscle is different from every other muscle\nThe heart's constant activity creates two vulnerabilities that this formula addresses simultaneously.\n\n\nVulnerability 1 · Energy\nSkeletal muscles rest between contractions. The heart does not. It has the highest concentration of energy-producing machinery of any tissue in the body. When that energy supply is insufficient, the heart cannot sustain its function. It becomes weaker.
