can zinc boost thyroid healthThere’s certain nutrients that maximise your thyroid health. One such nutrient is zinc as it’s vital for healthy thyroid hormone activity. This article answers the question ‘can zinc boost thyroid health’?

It’s widely known zinc is vital for your wellbeing as this mineral is found in virtually every cell of your body, and it’s involved in a wide range of metabolic reactions.

Can Zinc Boost Thyroid Health?

Let’s look at three ways zinc supports thyroid health.

+ Aside from iodine, thyroid function can be affected by a number of minerals, particularly zinc and selenium.

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 and a sufficient amount makes a real difference to how you feel. What you may not know is that low T3 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.

+ 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. The reason? Your thyroid hormones play an important role in firing up the immune response to help protect you from pathogens.

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

There’s evidence high copper can have a devastating effect on brain and cognitive health. Protecting your neurological health is an important consideration when you have a diagnosed thyroid disorder. You can read more here: Can Copper Harm Thyroid Health? Here’s What You Need To Know.
