Is your feline suffering because of hyperthyroidism? Startled on its dietary management?

We have come up with a well-researched diet that provides the happiest and healthiest life for your companion.

Hyperthyroidism is not a big deal to feel worried about, we can easily manage it by providing an iodine-restricted prescription diet.

Let’s say a big no to medical treatments. Although the restriction prescription diet has no side effects, there may be some effects because of long-term restrictions on Iodine.

But it is still under research nothing is proven yet. So now, let’s understand the reason behind iodine restriction. Hyperthyroidism needs an adequate iodine intake to produce thyroid hormones.

If the food served to cat has iodine levels of 0.32 parts per million or less then we can gradually reduce the amount of thyroid hormone production too.

Cats who are under a prescription diet for hyperthyroidism should never have any treats, human food, strictly any hunting or scavenging.

Now, let’s dwell on the topmost food product which is specially designed for hyperthyroidism cats.
