can zinc boost thyroid healthTreating hypothyroidism is not just about taking medication. You may also want to consider taking specific vitamins and minerals to support optimal thyroid function.

This article answers the important question ‘can zinc boost thyroid health’?

It’s widely known zinc is vital for your overall health. This mineral is found in virtually every cell of your body as it’s critical to support a wide range of metabolic reactions.

Let me explain more…

Here’s THREE Ways Zinc Supports Optimal Thyroid Health

ONE: Zinc teams up with selenium to support T4 to T3 conversion.

Zinc teams up with selenium to aid conversion of thyroxine (T4) to its more active form triiodothyronine (T3). If you are low in either of these two nutrients conversion is impaired.

As you may already know from first-hand experience, T3 is your most active hormone. Adequate free T3 can help overcome the effects of slow metabolism, and many other symptoms of a low thyroid.

When T3 is low it can indicate an under conversion issue. That is, T4 is not converting efficiently through to active T3. Zinc and selenium can help correct a conversion issue. For this reason, taking both zinc and selenium can be a real game changer.

TWO: Traditionally zinc has been used to support immunity as it improves resistance to infections.

This makes it an important mineral to consider for proper immune system function.

It’s common to experience lowered immune system function when your thyroid is under active. You see, the thyroid hormones play an important role in firing up the immune response to help protect you from infections.

THREE: Zinc has a protective role within the central nervous system, including defending the neurons from excess copper.

The body finds it difficult to process and excrete excess copper which can lead to a copper overload. This is a common problem, especially in women as estrogen increases copper retention.

There’s evidence high copper can have a devastating effect on brain, and cognitive health.

Zinc is a natural antagonist to copper. So when zinc goes up, copper goes down. For this reason, zinc helps protect your central nervous system from excess copper.

Protecting your neurological health is an important consideration when you have a diagnosed thyroid disorder. You can read more on this subject here: Can Copper Harm Thyroid Health? Here’s What You Need To Know.
