Extra t3 after run/exercise?

[Clara9]

I feel very tired and irritated after I have run for say 6km. Can I take a little extra T3 (5mcg)? Anybody who needs to do that?

Am taking 100t4+20t3

Ft3 5.3(3.6-6.3)

Ft4 19 (12-22)

I know some who add before they workout up to 5mcg T3 before they experience muscle issues .

This is something I have often wondered myself. Not that I am running or going to the gym but I run my own fashion business on a part time basis. I go for months doing nothing but then everything starts up again and I am manic for six or so weeks. I quickly become exhausted. I am in a completely different routine and if I had a thyroid, presumably it would send out more thyroid hormone. Should I be taking either more T4 or more T3 or nothing extra at all?

I hope someone knowledgeable can answer this thorny question for all of us.

Many thanks

You would need to know your FT4 FT3 TSH values before you start increasing your thyroid meds . T4 if you have enough wiggle room would be fine because you would have enough T4 to convert to the more active T3 that our muscles use/need . T4 is a longer acting thyroid hormone . T3 is a faster acting thyroid hormone and stays shorter time in our system .

Thanks, yes, I know what they each do but working out which is better is easier said than done. My instinct is for a little more T3, as I will get a quick fix! Also I am not sure I convert T4 very well. It is all a minefield but I know I have room to manoeuvre as neither is top of its range.

I don't actually think that anyone feels completely normal without a thyroid. They might like to think they do, but I believed that many have been so ill for so long that although they might feel better when corrected medicated they are not the same as a normal person with a fully functional thyroid is. If I do lots of exercise the next day I am feeling dreadful.. I have heard a few people on here just take a very small amount of T3 before running or the gym.

I absolutely agree and yet you will find people on this site who say they are absolutely fine, running marathons, climbing mountains etc. I am very puzzled. Maybe a bit of their own has grown back, as it has been known. I wish mine would oblige...

Well I agree, I am 72 years old and just before my thyroid was removed in 2015 I was on no medication and my thyroid was still working well. I was swimming twice a week doing Yoga everyday and walking about 12 miles a week too.

I used to be a runner until my gallbladder was removed in my sixties how I would love to run again.

I do find it hard to believe that some people manage to feel the same and perform too after their TT.

Why not try just a little T3 before your run and see how it goes, it could be your answer I hope so.

[Hennerton in reply to Hidden]

I am not the runner here. That is Clara9. I run a business that starts up and then after six weeks dies down until the next time. It can become manic after months of normal life, which was why I wondered about intermittent extra T3 as and when needed.

I am definitely not the person I was before thyroidectomy. I am more anxious, have much less stamina and am always suffering from musculoskeletal problems. I blame the loss of hormones that we do not know exist. They will probably discover the missing links in a 100 years and feel pity for us, those long ago thyroid sufferers...

Exactly I made a mistake.

I can't run, but do take a bit more the morning before increased activity as taking it later in the day makes it harder to get to sleep.
