Raising/Lowering Thyroid Meds

I'm on 75mcg of T4 and 25mcg of T3. Latest results are:

TSH: 0.01 (0.3 - 5.5)

FT3: 5.2 (3.5 - 6.5)

FT4: 14.1 (9 - 2.5)

Still have some hypo symptoms. I've tried raising T4 but had increase in dry skin, constipation, etc. Can I drop some T4 and raise T3 a little more? Or is there something else going on? Thanks.

Symptoms can lag behind good biochemistry by a couple of months but you can probably increase T3 to 31.25mcg without FT3 going over range. There's no need to reduce T4 as FT4 is low in range.

Are ferritin, vitamin D, B12 and folate optimal? Low/deficient levels can cause symptoms which are very similar to hypo symptoms.

Thank you Clutter

Ferrin, folate, B12 and D are good. Will try increase in T3.
