Palpitations with T3.

Just after you take it? Split the tablet down and take a bit every 4 hours

Before you take it?are you nervous? Or it could be that you're not taking enough.

Palpitations can be just thyroid related so no real trigger so it's hard to advise but lots of people get them, they won't kill you.

Try splitting your T3 into 4 doses during the day, that suits aot of people.

My experience it can also be adrenal related. It’s worth looking at adrenal imsuffiiciency symptoms. My cortisol isup and down like a weston donkey and it causes me palpitations and low blood pressure, which can be frightrning. If it’s stress related it can be helped by meditation

It's advisable to check out DHEA-S levels too .

Hello it’s before I take my meds

I would still split it then you wouldn't be so low before meds and you could rule out a hypo cause

I know when my dose is due because I get palpitations, I take 20mg 3x a day and feel amazing! I never forget a dose as I feel my palpitations are nature’s way of reminding me!

So happy T3 is working well for you. It should, it's what T4 converts into! When we can't wait on conversion that seems to never occur, or we can't convert at all, then T3 is the way to go. No doubt about it. It is also great as a supplement to boost T4 in those who are a bit sluggish in conversion. But small doses apply there so as not to keep T4 from converting.

You are so right! Those palps tell you there's need for an adjustment.

When honing in on the right dosing, it's just a smooth sail from one dose to the next -- with no palps at all. Perhaps taking it thirty minutes before the time you usually feel palps would be better for maintaining an even keel.

Set your watch. It's important not to stress the body by making it wait. We all want to heal as quickly and painlessly as possible.

If you meant you only feel palps when you're very late taking it, then that should be fine. Once you always take it on time, you'll notice a huge difference. If you already do, then kudos to you!

Hope this is helpful to you and others.

Hugs!

Thank you, I do mean that it’s only if I’m very late with my meds that I get palpitations. It’s interesting to note that I also take 250mg of T4 which is a fairly high dose but when I have tried reducing to 200 I’ve become symptomatic. I’m so well now I fear the meds being taken away from me!

You might want try NDT if synthetic T3 is giving you palpitations . T3 from the NDT is a smoother delivery of T3 and you don't get those surges . You might also try to check out if your nutrients are up to par . Low Iron can cause palpitations too . Check out SeasideSusie's Excellent posts on vitamins .

bossbird ,

My sympathy for you . I would try to dose about a half hour before you usually feel the surges and take it with some small snack . Try to keep a log how much before you feel the surges ? Try to see if you can dose before they come on . See how that works for you .

With all due respect, then you should be taking T3 if you are overtly T4 resistant. Most everyone has some resistance to T4, as the body often makes it but cannot properly utilize it due to malabsorption and nutrient deficiencies. Adding more T4, in that case, certainly isn't an answer. If you haven't tried T3, there's no doubt it it is your answer. I'm hoping you already do use T3 and are in good health. Hugs to you!

I recently moved to T3 only (50mcg), which I take on waking.

When I wake up, I feel kind of hyper & clenching my teeth.

If I felt like that AFTER taking T3, I’d think my dose is too high, but it’s 24hrs after taking & it goes away once I’m up.

My guess is it’s Cortisol related, but I never experienced this until recently..

This feeling is only when I wake up & goes away quickly, so I don’t know if it’s the T3 dose or just getting up that fixes it. I’ll maybe try delaying my T3 to see if the feeling goes away itself.

Good luck finding your cause.

Teeth clenching/ grinding during sleep can indicate SIBO and parasites particularly noticeable 5 days either side of full moon.

What does the full moon have to do with it?

mourneadventurer profile image
mourneadventurer in reply to Kangagirl

It’s something to do with the moons gravitational influence on water and animal activity. I found I couldn’t sleep as well. Then after I did the GI map test by Invivo it all made sense.

OK, thanks. That's interesting.

Could be food including sugar related and possibly linked with insulin resistance?

More electrolytes needed as your body gets used to an increased metabolism? I take Researched Nutritionals Core Minerals at the recommended dosage and also Quinton Hypertonic (am) Isotonic (pm).

I get palps when iv forgotten a dose and because my cortisol is so low. However what I consider palps are very different to others. For years my heartbeat was slow (50-55 bpm) and weak. It was a real shock on T3 to actually feel my heartbeat and it is a healthier 70bpm resting. Mine never skips or flutters iv had ecg cardiogram etc and all is very healthy x

If just before, could be you aren't taking enough and the palps are telling you that you need more. Or it could be a coincidence and your Ferritin is low (under 90-110). Low ferritin can cause palpitations and many other hypo symptoms. They work hand in hand, as when ferritin is not high enough to facilitate proper thyroid function, then you have symptoms that are akin to hypothyroidism. This can occur even when taking T3.

The beauty of T3 is that it only lasts a few hours. Easy to test by lowering the amount for the next dose. In your case, since the palps occurred at the beginning of your next dose, I'd say your body was telling you it's time for more. Might need a bit more T3 or shorten the time in between those doses.

Hope this helps!
