McCall McPherson explains how your body converts thyroid hormones into T3, the active form that controls energy and metabolism. Most people get T4-only medications like Synthroid, but many can't convert it to T3, leaving them symptomatic. Instead they build up reverse T3, which blocks the hormone that actually works.

Whether you're subclinical or normal hypothyroid, if you are getting worse, not feeling better, or your reverse C3 is increasing on your medication, let's talk about why. So there is a very specific reason people generally are not getting well despite being treated for their thyroid problem or that they're even getting worse. So I'm going to show you a diagram here below and I want you to look at the thyroid biochemical cascade. Okay, so we have your tsh. It goes to stimulate your thyroid and your thyroid secretes free T4. Free T4 is that middle hormone. Down here, it's crude oil. It's completely inactive hormone. It does you 0% good until it's activated. When it's activated in its activated form, it goes over to your free T3. Okay? That is your gasoline. I compare it to crude oil and gasoline. We don't put crude oil in our car to make it go. We need it to make gasoline to put in our car. Same with our thyroid hormones. If we don't have, if we can't make gasoline from crude oil, we're not going anywhere in our car. Same situation. Your gasoline hormone is your free T3. You need this to think, to have energy, to have a metabolism, a libido, digestion, hair, skin, nails, hormones, all the things you need, you have to get to free T3. What's happening is a lot of people on or off of meds even don't activate their crude oil. Well, most people who are being treated with thyroid hormones, in fact, 99% of people are being treated with T4. They're being treated with crude oil hormone. Just expecting and assuming that these people can convert that crude oil to their gasoline hormone. And you know what? They can't. Most people can't. You probably can't. So what's happening is you are stockpiling a lot of crude oil. And what that does is it creates a source for your inhibitory hormone, your reverse T3. Reverse T3 is shaped just like your T3. Your gasoline hormone in reverse, like our hands, that allows it to bind to the same landing spot as T3. But instead of activating that landing spot for your energy or your libido or your metabolism, reverse T3 just sits there, doesn't let T3 bind. So what's happening inadvertently by treating everyone with levothyroxine, synthroid, unithroid, T resent, T4 based medications, not only are they not converting that T4 to T3, most of them are simply creating a source by taking all that T4 to increase their reverse T3. So important. Share this with a friend. Engage with this content so more people can understand this. Because millions of women, y', all, millions of women are suffering for no good reason. It's a fixable problem.
