Thyroxine at 5/6am??? Is there a reason why it works better at this time?

Hi Guys,

The last few days (it started accidentally) I started taking my thyroxine super early at 5 or 6 am and then going back to sleep and it seems to be working so much better than taking it at night or at a normal hour in the morning (like 8am). Is there a scientific reason why that happens (or is my body just messing with me and making me do stuff at sunrise)?

In the morning I used to take it alone and wait for an hour before coffee, eating and vitamins; in the evening I used to take it with 5htp, tyrosine and melatonin (So i guess there might have been some hormonal infighting there?)

Just out of interest- I just thought it was a bit odd.

Thanks so much! That is indeed interesting. May be it correspond with the body's natural ft4 high so it's more agreeable?

vixvixvix I am the same. The only trouble is that if I do sleep later it messes it all up again and the following couple of days I don't feel so good. But definitely noticed the early hours thing yes!

Oh I hope not! I just go back to sleep. I work late so 5:30 am is like 4 hours in!

This is just a guess.

There is a circadian rhythm to cortisol as well as some thyroid-related hormones. Perhaps your cortisol levels are better at 5am - 6am rather than a couple of hours later. If the cortisol levels are just right for you at the earlier time then you may be getting better conversion from T4 to T3.

Didn't mean my link to be an answer so much as a bit of information to the mill of understanding. :-)

I have always taken mine at bed-time so am a very bad person to actually ask - no experience of taking it at other times.

You shouldn't be drinking coffee, caf or decaf, or normal/green tea at the same or similar time if you need to take vitamins/minerals.

You also shouldn't be drinking tea or coffee while eating regardless.

Simply as tannins and caffeine interfere with vitamin and mineral absorption.

You should leave a couple of hours either side.

Ha I know, but between that, Fat coffee before the gym, no anything for about 1 1/2 hours before the gym (even then it's a minor miracle if I don't feel sick, my digestion is SLOW), work, vitamin only in the morning (any time after 10 I'm still too buzzed at night), it's really not doing the job 100% or not taking it at all. Otherwise I'll be starting my morning routine at 4 am!

But thanks for letting me know :).
