Change dose or not?

I'm taking 100t4+15t3

Latest results

Tsh 0.01

Ft3 5.6 (3.6-6.3)

Ft4 19 (12-22)

Do you think I can change dose to either 87 t4 and 20 t3 or 75t4 and 20t3?

I'm not feeling well still so want to try to find my sweet spot. And I can't get an even dose of t3 when I need to break them into four.

Any advice welcome please.

Your FT4 is 70% through it's range and your FT3 is 74% through range. For many people that would be perfect, for others not. It's a very individual thing and experimenting is the only way you can know where you need your levels for you to feel best.

As you find splitting the T3 into 4 difficult, and I'm presuming they are 20mcg tablets, you could try 20mcg. Assuming that is prescribed, do you have enough? See how that goes, you may need to reduce Levo but don't do both at the same time.

I found it took a very long time tweaking my meds to find the right levels for me.

Are your nutrient levels optimal?

Do you have Hashi's?

Hi,

Yes, all vitamins are good.

So your advice is to increase t3 to 20 and see how that goes and if I feel over then reduce t4 a bit. Is that right?

Not advice, I'm not qualified to give advice. My suggestion is that you could try it and see how it goes. You can always reduce if necessary.

Are you taking your T3 in split doses?

Some of us need steady levels achieved by 3 doses per day (every 8 hours)

I agree it's tricky to take exactly 15mcg daily

(You would think, it would/should be possible to make 5mcg T3 tablets far more widely available)

You could try 10mcg in morning, 5mcg afternoon and 5mcg evening

Cutting using a sharp craft scalpel makes it slightly easier to cut into four (or into 1/2 plus 2 x 1/4)

Possibly reducing Levo .....perhaps leave Levo as is initially

T3 is the active thyroid hormone which controls the metabolism and therefore the symptoms. Your Free T3 is in the top part (74%) of the normal range, which is good, so you should not have hypothyroid symptoms.

As you are still having what appear to be hypothyroid symptoms, one possible cause is a genetic condition commonly known as Thyroid Hormone Resistance. It causes hypothyroid symptoms and requires very high T3 levels (often above the top of the normal range) in the body to overcome the resistance.

As it is genetic if there are other family members with thyroid problems, fibromyalgia, CFS, ME, Coeliac Disease, MS, Heart Disease or depression this would further support this possibility. Even if you cannot identify any family history of this it is still possible that you have this condition.
