If your cat or dog has been diagnosed with hyperthyroidism, you are likely searching for ways to support their health beyond medication. You might have heard about bone broth as a nourishing addition to their bowl. It is true that a good bone broth can offer gentle support, but it is important to understand how it works, what it can and cannot do, and how to use it safely. This article walks you through the real effects of adding bone broth for hyperthyroidism, so you can make an informed choice for your pet.
What Is Hyperthyroidism and How Can Diet Help?
Hyperthyroidism is a condition where the thyroid gland produces too much thyroid hormone, speeding up your pet’s metabolism. In cats, it is common and often causes weight loss, increased appetite, restlessness, and a rapid heart rate. In dogs, it is rarer but can occur with thyroid tumors. Diet alone cannot cure hyperthyroidism, but it can help manage symptoms and support overall health. Bone broth fits into this as a nutrient-dense, easily digestible liquid that can encourage eating, provide hydration, and supply amino acids like glycine and proline, which support the liver and kidneys. Since hyperthyroidism puts stress on these organs, a gentle broth can be a helpful part of a broader care plan. Always pair dietary changes with veterinary treatment, such as medication or radioactive iodine therapy.
The Key Nutrients in Bone Broth That Support Thyroid Health
Bone broth is rich in collagen, gelatin, and amino acids. Collagen breaks down into gelatin, which helps soothe the digestive tract. This is important because hyperthyroid pets often have sensitive stomachs or diarrhea. The amino acid glycine supports detoxification in the liver, helping to process excess thyroid hormones. Proline and glutamine also aid in gut repair and immune function. However, bone broth is not a source of iodine, which is critical for thyroid function. In fact, too much iodine can worsen hyperthyroidism in some cases. So while bone broth provides supportive nutrients, it does not directly lower thyroid hormone levels. Think of it as a gentle foundation, not a treatment. For a deeper look at thyroid-friendly foods, see our guide on thyroid diet for cats.
Bone broth has been used for centuries in traditional diets for sick animals. The slow simmering process extracts minerals like calcium, magnesium, and phosphorus, which can help balance electrolytes in pets who are losing weight or not eating well.
How Bone Broth Can Help With Common Hyperthyroidism Symptoms
One of the biggest challenges with hyperthyroidism is weight loss despite a ravenous appetite. Bone broth can be a calorie-dense, nutrient-packed addition to meals. You can pour it over dry food to increase moisture intake, which supports kidney function. Many hyperthyroid cats also develop kidney disease, so hydration is critical. The broth’s aroma can entice picky eaters, helping them maintain weight. Additionally, the gelatin in bone broth may help reduce inflammation in the joints, which is beneficial if your pet is restless or has trouble sleeping due to the condition. Just remember, bone broth is not a substitute for veterinary-prescribed medications like methimazole or thyroidectomy.

Choosing the Right Bone Broth: What to Look For and What to Avoid
Not all bone broths are created equal. Many store-bought broths contain onions, garlic, or high sodium levels, which are toxic to cats and dogs. Always read labels carefully. Look for a broth that is made from organic chicken or beef bones, with no added salt, no onions, no garlic, and no preservatives. You can also make your own at home by simmering bones in water for 12 to 24 hours. If you buy commercial pet bone broth, choose a brand that is specifically formulated for pets. Avoid broths with added vegetables like carrots or celery if your pet has a sensitive stomach. The goal is a simple, clean liquid.

How to Introduce Bone Broth Into Your Pet’s Diet Safely
Start slowly. Add just one teaspoon of bone broth to your pet’s food for the first few days, then gradually increase to one tablespoon per 10 pounds of body weight per day. Watch for any digestive upset, such as loose stool or vomiting. If your pet has a history of pancreatitis, be cautious because bone broth can be high in fat. You can skim the fat off the top after cooling to reduce this risk. Always serve bone broth at room temperature or slightly warmed, never hot. It can be used as a topper, mixed into wet food, or offered as a separate treat. Do not replace a meal with bone broth unless your vet advises it. And if your pet is on a prescription diet for hyperthyroidism, check with your vet before adding anything new.
When Bone Broth Might Not Be the Best Choice
While bone broth is generally safe, it is not for every pet. If your pet has a known allergy to beef or chicken, choose a broth made from a protein they tolerate, such as fish or turkey. Also, if your pet has advanced kidney disease, the phosphorus content in bone broth could be a concern. Hyperthyroidism often coexists with kidney issues, so ask your vet to check your pet’s kidney values before adding bone broth. Finally, if your pet is on a strict low-iodine diet for hyperthyroidism (common in cats being prepared for radioactive iodine therapy), bone broth may contain trace amounts of iodine from the bones. In that case, it is safer to avoid it. Always prioritize your vet’s guidance over any online advice.
Bone broth is a supportive tool, not a treatment. Hyperthyroidism is a serious medical condition. Always follow your veterinarian’s treatment plan and never stop prescribed medications without consulting them.
