Best Thyroid Health Supplements: What are they?

A good question! There are many different types of thyroid health supplements. Some of them have been around for years while others were just recently introduced into the market. Most of these products contain various herbs or minerals. These include but not limited to; L-Tyrosine, T4, T3, Zinc, Copper and Manganese.

You may wonder what exactly is L-Tyrosine?

It’s a naturally occurring amino acid found in meats such as beef liver, chicken livers, turkey livers, pork liver and fish liver. It has a very high bioavailability and it’s effect on the body is similar to that of leucine. In fact it has even higher bioactivity than the famous muscle building protein known as “Leucine”.

L-Tyrosine is considered one of the most powerful thyroid boosters available today. It increases the production of T4 (thyroxin) and T3 (T4 precursor). Studies show that L-Tyrosine supplementation can increase your natural production of both hormones by up to 10 times. This means that you will produce more T4 and less T3 than someone with no dietary intake of L-Tyrosine.

The supplement has been proven to increase the levels of dopamine and norepinephrine in the brain, both of these are natural antidepressants.

T4 is an inactive hormone and it requires transformation into T3 in order to provide your body with adequate levels of thyroid hormones. While T3 is the most bioactive form of thyroid, it is also the least abundant. Your body can’t produce it on it’s own so you need to get this from your diet. This is why it’s so important to eat foods such as eggs, fish and meat especially beef liver and kidney.

If you don’t get enough T3 in your diet, it’s a good idea to supplement with a T3 containing thyroid health supplement.

Best Thyroid Health Supplements: A Closer Look

There are many different types of thyroid supplements on the market today. It is important to choose a product that is high quality yet still affordable. There are many cheap thyroid health supplements out there but many of them are ineffective and some may even be harmful to your health. It is always important to choose a product that has been well reviewed and recommended by professionals.

Look for thyroid supplements that contain ingredients such as Tyrosine, Zinc, Iodine, SELENIUM and T3. Make sure that the supplement contains no more than the recommended daily dose of iodine.

You’ve probably heard of most of these ingredients before but you may not know exactly what they do or how they work. Well let’s go over each ingredient and explain a little bit about what they do.

Tyrosine: is an amino acid that functions as a precursor for the thyroid hormones thyroxine and triiodothyronine. This means that it acts on the thyroid to produce hormones that increase the metabolic rate.

Zinc: is an essential mineral that is very important to proper thyroid function. It is required for the production of the TSH (Thyroid Stimulating Hormone). A deficeincy of Zinc can cause a decrease in the activity of the thyroid gland.

Iodine: is an element necessary for the production of the thyroid hormones thyroxine and triiodothyronine. A deficiency of iodine can cause inhibition of the production of these hormones.

Selenium: is an important trace element that works synergistically with iodine in the production of triiodothyronine and thyroxine. It also functions as an antioxidant in the body and protects cells from free radical damage.

Tyramine: is found in many foods such as aged cheeses, cured meats, beer, yeast extracts and others. An excess of tyramine can increase the production of noradrenaline and cause an overproduction of adrenaline. This may lead to an overactive thyroid.

Pantothenic Acid: is a type of vitamin B that is important for many metabolic functions in your body. It is required for the synthesis of hormones such as thyroxine and cortisol.

Having a healthy and properly functioning thyroid gland is very important if you want to live a long and healthy life.
