why has my brain fog got worse on T3.

been on t3 for 8 months and brain fog has come back quite bad not to mention the really bad fatigue after work or exersise . im on 60mcg taken 4 times a day.latest bloods tsh- 0.02 t4-0.9 t3-5.1, it went when i was on armour but due to cost on nhs they put me on t3. one days work and im useless the next day! any ideas

Nataliesue, I'm surprised your FT3 isn't a little higher on 60mcg. Was FT3 higher when you were on Armour?

hi ive just looked at old results (doh) and yes it was higher 6.4 so perhaps i will up my dose a bit. but im thinking of also taking a small amount of ndt when i decide which one.

You may need a rise in your dose of T3. The results above - did you leave an appropriate gap between your dose of T3 and the blood test?

I know some do split their daily dose of T3 but I don't. Just for info this is a link which may be helpful. Extracts:

"You mentioned our "T3 protocol." It’s important to understand that this term is not an accurate designation of our protocol. Many people mistakenly believe that our protocol solely involves the use of T3. They do so, I suspect, for a particular reason: About a third of our fibromyalgia patients have thyroid hormone resistance, and these patients improve or recover only with the use of T3—although they must use T3 within the context of a comprehensive program of metabolic rehab. How this information translates in some people’s minds into our protocol solely involving T3 is beyond me.

Most of our fibromyalgia patients have either primary or central hypothyroidism. These patients improve or recover with the use of desiccated thyroid (such as Armour)—but, again, only when they use desiccated thyroid within the context of a comprehensive program of metabolic rehab"

And finally, why do I specify that the typical patient use one full dose of non-timed-release Cytomel for life? Because extensive testing has shown that this is safe, effective, and most economical—when used within the context of our entire protocol

"Their study results make one thing clear: Circulating free T3 and T4 levels don't allow us to accurately predict the T3 concentration in the cells of most tissues. The evidence suggests that there is simply too much variability between different tissues in the same patient. Moreover, there's too much variability between the tissues of different patients. Even more difficult is accurately predicting the physiological and clinical effects of different circulating free T3 and T4 levels. Again, there's simply too much variability to allow accurate predictions.

Barnes was right when, long ago, he wrote that circulating levels of hormones don't measure what's most important—how the patient's tissues are responding to a dosage of thyroid hormone. Our regimen involves multiple measures of how tissues are responding to a particular dosage, repeated at short intervals in a highly systematic way. Our model of assessment is taken from behavior modification, in which I was trained in the early 1970s. We know from hundreds of trial runs that we can precisely control the metabolic status of most patients only by using these multiple measures of tissue response. We adjust each patient's dosage until these measures tell use we've achieved normal tissue metabolic status—regardless of what the patient's circulating hormone levels are. I concede that you can do some fairly good tweaking by using free T3 and T4 levels. But still, if the patient's tissue responses aren't carefully assessed, the clinician isn't focusing on what's most important—the patient's physiological and clinical responses to treatment."

yes i think i need to raise, and i took last dose at 4pm and had test next day at 11am

[shaws Administrator in reply to Hidden]

As doctors are apt to adjust dose according to the TSH I think it's best to leave 24 hours between last dose and blood test particularly when taking T3 only.

ok thanks will do that next time

Also NatalieSue, this may be of no use to you, I realise what works for me might not for you, but I found my brain fog went when I went gluten free. So if you haven't done that already it might be worth trying. Hope you sort this. Best.

[Hidden in reply to Hidden]

hi thanks yes been gluten free for 2 years also dairy,yeast,eggs etc the list goes on.

Any exercise uses up T3 and perhaps that is why.
