Causes for thyroid deficencies

I have 2 standardbreds with similar numbers from blood work after racing this month theT-4 were low <0.5
My vet can't provide a causative factor for this condition along with high SGOT numbers 10400 SGPT 68
CPK41000 Any help would be appreciated.

In case you are still looking here...

Thomas, I would first like to say that I am not a vet or doc, but due to my own health struggles I have looked more closely at my horses. I was not surprised to see your liver numbers out of range along with low t4. Ultimately what I have found is that if your support all methylation pathways nutritionally through the liver (where many hormones are made and disbursed) then everything gets a whole lot better. If you look at human fatty liver disease and support with nutrients choline (lecithin), betaine (TMG), probiotics/enzymes, possibly milk thistle and similar support for phase II detox, hormone levels tend toward better balance. I have had some luck with spirulina also (20 gms/day, divided dose). I use extra unfortified brewers yeast for SE and other minerals, and 1/2 serving of Source micronutrients for iodine along with ration balancer Frederick CoOp Fortify. Also, folic acid will compete with and can block natural dietary folate (not a good thing), as it will also slow the main methylation pathway (methionine cycle) and homocysteine levels can sometimes rise. I have not seen documentation of this in horses with the exception of one paper by Amy Burk at Univ. of MD. Nonetheless fresh grass is always best source for folate if tolerable and I try to minimize synthetic folic acid. Few vets are aware of this. Bloodwork is not always revealing as often liver enzymes are fine. IR and similar hormone imbalances rarely exist (in people) without first having a slow down in the liver unless diet is completely ridiculous. Key is that all nutrients/cofactors must be available in the diet, and the horse must also be absorbing them which is often not the case for any multitude of reasons. I have found same in my horses. 4 laminitis horses all with varying degrees of IR, ages 11-17 are now on pasture 24/7. Not everything fixed but pretty sound in bare feet and all are ridable, as slowly subtle signs like coat changes, fat deposits, overweight, diarrhea etc are improving. Your milage may vary, but worth looking at I think, since you are looking. Hope this helps you and your horses! For my boys the addition of brewers yeast and probiotics/enzymes was huge but only in combination, not in isolation which was interesting to me. I use the Command FT probiotic from Valley Vet at maximum dosage. These things have changed the game here, but still a work in progress. Still, I will take any improvement. :)

iodine and thyroid

can excess iodine damage the thyroid and can the damage be reversed?
