Thyroid Hormone Levels: What is Normal?
Are your thyroid hormone levels getting you down?
Hypothyroidism is a condition in which the thyroid gland doesn’t produce sufficient amounts of hormones. People often feel fatigued, gain weight, get depressed, have trouble concentrating, and develop skin problems or fertility problems, among many others. Blood tests determine one’s thyroid hormone levels, which can indicate if the thyroid isn’t functioning as it should. Hypothyroidism is often treated with medication, but there are also natural treatments available.

Thyroid Function
The thyroid gland sits at the front of the neck, below the larynx. It takes in iodine and converts it into the two thyroid hormones: triiodothyronine (T3) and thyroxine (T4). These hormones are extremely important because they control metabolism, which is why people with thyroid problems commonly have weight problems. When thyroid hormone levels drop, the pituitary gland produces Thyroid Stimulating Hormone (TSH), which then causes the thyroid to produce more T3 and T4. That’s why presence of TSH may indicate problems with the thyroid.
Testing Thyroid Hormone Levels
There are a myriad of different blood tests that measure thyroid hormone levels. When testing for hypothyroidism, doctors almost always order a TSH test. Normal TSH levels are between 0.5 and 5.5 mIU/L. Among conventional doctors, the TSH test is considered the best way to determine if there are problems with the thyroid.
Free T3 and Free T4 tests measure the amount of free, unbound T3 and T4 in the blood. The normal range of free T3 is from 230 to 420 pg/dL. The normal range of free T4 is from 0.8 to 1.8 ng/dL. Laboratories may have different normal ranges based on their instruments, which they note on the lab test results. And people’s levels may be at the low end of normal, but they still need treatment.
There are also two tests that measure the presence of thyroid antibodies in the blood. When functioning correctly, thyroid antibodies should be nearly undetectable. If they’re significant then there’s likely an issue with thyroid function. Problematically, the presence of thyroid antibodies affects all the other thyroid tests.
Treatments for Hypothyroidism
Most often, doctors prescribe synthetic thyroid to replace the hormones that the thyroid isn’t producing. Synthroid, also known as Levothyroxine, is the most common medication. Unfortunately, like most medications, it can have significant side effects. Either because of those side effects or due to concerns about taking synthetic hormones, some people are more comfortable with natural treatments for hypothyroidism. Since everyone’s case is individual, people should investigate all their treatment options before deciding.

#1 – Thyromine

The results we got with Thyromine were a real surprise to us. We knew that the right blend of natural ingredients were effective in relieving the painful symptoms associated with an under active thyroid. But we never expected a product with all natural ingredients to be so effective.
Whilst no thyroid remedy will work instantly, some users report feeling and seeing results after just a week and a half. After 3 months of using Thyromine many people report increased energy levels, weight loss, thicker hair and better skin.
We’ve chosen Thyromine as our number 1 thyroid treatment because of it’s enormous success rate amongst users. The powerful blend of top quality ingredients works to soothe your symptoms naturally, allowing you to enjoy the benefits whilst avoiding the painful side effects of many other modern thyroid treatments.

#2 – Thyax

Thyax is packed with high quality all natural ingredients which combine to create a very effective thyroid treatment and that’s why it has received great reviews and praise from many trusted sources. Why did this product come 2nd? This product only made 2nd place in our rankings as users found it took slightly longer to feel and see results than they did with Thyromine (and Thyromine also gave better results).
If you’re looking for an under active thyroid treatment that brings increased energy and allows you to lose weight after a few months use then Thyax is a worthy choice.
#3 – Thyroid Complex
Thyroid Complex has been around for a while, and whilst many people swear by it, we found the results produced by the product did not match the standard of Thyromine (or even Thyax).
However, Thyroid Complex is an adequate product packed with top quality ingredients, which provides relief for many sufferers of hypothyroidism. Whilst we know this to be an effective product, it's only good enough to give Thyroid Complex the 3rd position in our top 3 picks.
