What is the Optimal TSH Level for Your Thyroid Health?

It turns out that the TSH test is an important test to check for thyroid health.

Most labs will state that a normal TSH result will be between 0.5 to 4.5 mIU/L and some will say 0.5 to 5.0 mIU/L.

However, this is a wide range of values going all the way from 0.5 to 4.5-5.0 mIU/L.

Where do you really want to be when it comes to this range regarding your thyroid health?

It turns out that being somewhere in the middle, around 2.0 mIU/L, is really the ideal range that you want to be in.

What is TSH?

TSH stands for thyroid-stimulating hormone.

TSH is a hormone secreted by the pituitary gland that tells the thyroid to make more thyroid hormones, T4 and T3.

When a person's thyroid hormones are low, such as is the case in hypothyroidism, then the TSH will be high, because the body is looking to compensate for the low levels by signaling to the thyroid to make more hormones.

This is why a level that is skewered toward the high side, which is 4.5 mIU/L or above shows that a person is in a pre-stage for hypothyroidism. It may not be quite at the level to indicate hypothyroidism but it's close. Therefore, a value above 4.0 mIU/L really isn't optimal for thyroid health.

At the same time, you don't want levels that are too low, close to 0.5 mIU/L beacause this signals there is too much thyroid hormones, which signals hyperthyroidism. This is problematic also, because hyperthyroidism comes with its own health problems, including tachycardia, heat intolerance, shakiness, etc.

Ideally, you want to be somewhere around 2.0mIU/L, give or take.

This truly would signal optimal thyroid health.
