Details of Hyperthyroid Support

Is your fabulous feline strangely eating more but looking lanky? They could be suffering from Hyperthyroidism.

Middle-aged and senior felines are highly susceptible to Hyperthyroidism. It occurs when the thyroid produces too many hormones, speeding up the metabolism. It will often result in an overstimulated heart, digestive and nervous system.

Symptoms of Hyperthyroidism in cats:

  • Unusual or sudden weight loss
  • Scruffy or dull coat
  • Hyperactivity and irritability
  • Increased appetite and water intake
  • Frequent urination
  • Poor digestion, diarrhoea or vomiting
  • Vocalisation
  • Depression or lethargy

Hyperthyroid Support helps lower thyroid hormones in your cat’s body. This formula is crafted with revitalising, natural herbs that help support a calm nervous system and maintain healthy heart function.

Keeping the thyroid function balanced is essential for your cat’s general health and long-term wellness. The good news is you can use this effective formula indefinitely to improve the comfort and quality of your cat’s life.

The herbs used in Hyperthyroid Support have no known side effects, so they are safe for everyday use. This formula cannot be used in conjunction with pharmaceutical medications for Hyperthyroidism. For use in cats only. And rarely Dogs with Hyperthyroidism.

Untreated Hyperthyroidism in cats can cause major strain on the heart and kidneys. Natural or conventional treatment is crucial to managing this serious condition. If left untreated, Hyperthyroidism can be fatal. Please consult your Vet if you suspect your cat may have hyperthyroidism.

I bought it for my neighbours cat while I was feeding her for them and it was working very well

Kim Stevens
Looking better

My cat seems to be looking a lot better. Her coat is less matty and she has minor weight gain nothing to jump up and down about at this stage but it's only been a month.
I took her to the vet and had the blood test done to confirm it was Hyperthyroidism but chose not to use the Vets medication because of the side effects and risks. These drops on their own have made a difference. The dropper system works well and keeps everything clean without spillage.
Questions - 1. The dropper sometimes sticks and it is hard to get exactly the 3 drops, can say 6 or 7 drops be to much for a 3kg cat?
2. Is there a page to suggest foods my cat can eat now she is on these drops, my main interest is milk, she loves cow milk but I heard it has a lot of Iodine.
Worth trying for sure..

Monty's Miracle

My 20 year old cat has been given a second chance at life. Although he had developed an insatiable appetite he had become so skinny before starting Hyperthyroid Support. Now he starting to gain some weight and is again interested in his surroundings.
I highly recommend this product.

I am so glad Monty the handsome fellow is feeling better again!

Frequently Asked Questions

Is the Hyperthyroid Support Safe For My Dog Or Cat, Even If They Are On Pharmaceutical Medications?
Safety is of the upmost importance to us at Natural Pet Supplements. Hyperthyroid Support cannot be taken with pharmaceutuical medications to lower Thyroid function. Do not use with Blood Pressure Medications. The herbs chosen are specifically chosen because of safety and effectiveness in animals.

Caution is advised if the animal is diabetic or on blood thinning medications.

Do not exceed recommended dosage for weight, unless advised. For best practice all herbal formulas should be discontinued 2 weeks prior to surgery. If you have any queries about safety, drug/herb interactions, please contact us and we will back to you ASAP.
How long until I see results with the Hyperthyroid Support?

That depends, There are many factors that influence how quickly you will see results. Such as severity of condition, immune status, diet, stress levels, age, breed etc.

Positive results are generally seen in 2 weeks, although optimum results and changes in bloodwork will take up to 3 months to be seen. 

As herbal medicine is aimed at fixing the root cause of the illness instead of just negating symptoms, it is not instant. Patience is key, but if you aren't seeing results after 12 weeks, please contact us and we can reformulate the medicine to suit your pets individual needs, or you may have to increase the dosage. INDIVIDUAL RESULTS MAY VARY. INDIVIDUAL RESULTS MAY VARY

What If My Cat Doesn't Like The Taste?
Our herbal formulas are flavoured with a smoky bacon taste, and 98% of herbs are in a glycerine base, but the pungency of some herbs may still be present. 

Mixed into food is the easiest way for most pets, if not you can squeeze into the side of their mouth or mix into a treat like tuna, sardines or ricotta cheese.

Persistence is the key, you can always try to work up to the recommended dosage over a week or so.
