Welcome to the Dr. Berg's Healthy Keto and Interminute Fasting Podcast, where Dr. Berg takes you on the journey for the truth about getting healthy and losing healthy weight.

So if you have hypothyroidism, how do you have hypothyroidism, I highly recommend that you take cod liver oil.

Let's talk about why.

There are three main key nutrients that the thyroid needs.

Number one, it needs iodine.

And iodine makes up the thyroid molecule itself.

In fact, when we talk about T4 or T3, we're talking about the number of iodine molecules.

Then you have selenium. Selenium is involved in an enzyme that allows the conversion from T4 to T3,

the active form of the thyroid hormone.

So you need selenium, it's a trace mineral.

So about 80% of this conversion happens in the liver

and 20% happens in the kidney.

So you need a healthy liver,

and you need a healthy kidney.

But vitamin A is involved in this other hormone called thyroid-stimulating hormone,

which is created from the pituitary, and it's sent down to the thyroid.

So it tells the thyroid what to do.

And this whole chain of events is on a negative feedback loop. In fact, the way they

diagnose hypothyroidism is with the thyroid stimulating hormone. If the thyroid stimulating hormone goes

up because there's no negative feedback coming back, that's one way they would diagnose a hypothyroid case. And when you have a vitamin A deficiency,

you have a massive increase in thyroid stimulating hormone. And that can even increase the size of the

thyroid as a goiter and actually decrease the absorption of iodine. So vitamin A is very important in thyroid function. So we have iodine,
