My T3 is too high and need to reduce cytomel

10 months ago•10 Replies

Hello everyone

I test my thyroid with Lab Corp every 3-4 months. My T3 is over the range and I need to reduce the amount of cytomel. Im in the US and get Grossman cynomel. (cynomel is same as cytomel)

I do the testing exactly as this forum recommends.

Here are the results:

Triiodothyronine (free T3), 5.5 (range is 2.0-4.4 / pg/mL)

Thyroxine (free T4) 1.34 (range is .82 to 1.77)

TSH 0.005 (range is 450-4.500 uIU/mL

For the last 3 years, my TSH has been the same. It is suppressed. BUT T3 is too high.

I take 100 mcg of Synthroid and 25 mcg of cytomel.

2 days ago I changed my cytomel to 17 mcg. (the pill is a 25 mcg).

How long should I stay at this level before I reduce the cytomel to 12.5 mcg?

I do not have any symptoms of overactive thyroid at all. But I am getting headaches now. My PC said headaches could be from thyroid issues. Thanks for your input.

I would test after 8-10 weeks on 17.5mcg

Do you normally split your dose,

when were vitamin D, folate, ferritin and B12 last tested

What vitamin supplements are you taking

thank you for your reply. I have tested vitamin D folate ferritin and B12 three months ago and they were all within normal range.

I don’t take magnesium because I’m on a blood thinner /Eliquis. I take a vitamin C, and every other day take an iron supplement.

interesting I don’t have any symptoms of hyperactivity. I don’t split my dose. I take my Synthroid at 1 AM and my cytomel at 3 AM then I get out of bed at 6 AM.

So day before thyroid test do you split your T3 into 2 or 3 smaller doses spread across the day

Last dose should be 8-12 hours before test

I have tested vitamin D folate ferritin and B12 three months ago and they were all within normal range.

Normal is not necessarily optimal

Please add actual results

Yes split into 2 small doses. Thanks

What are vitamin results?

What time did you take the T3 the day before the Bld draw? Were blds taken at 9am? I might have missed that.

I can also feel when my t3 is too high and I get the jitters badly. I take 62mcg Synthroid and usually 30mcg of porcine. I just cut my porcine in half for a few days and I feel good. Will take the 30 every 3 days and then back to half for a few days. You can usually feel when it is too high.

Where do you buy the Grossman Cynomel at?

⚠️ IMPORTANT! When you receive a message with a recommendation, please do not assume it is genuine!

Scammers are joining the forum on a very regular basis and messaging members with their assertions that they have successfully purchased xyz medication from zyx source.

Once you have what you think may be a genuine recommendation, you are strongly encouraged to message an Admin to ask whether the admin team have any feedback on the source you've been given.
