Re: High T3 8.7 (range 3.5-6.5)

[Guest guest]

The brain does NOT need T4 you can quite happily exist on T3 alone.

Dr LOwe has been on T3 ONLY for over 20 years!!!

If you took your T3 2 hours BEFORE the test your T3 levels will be MUCH lower

than your results. You just measured the peak after taking your meds. On Rt3

group we recommend testing early am & at least 12 hours since last dose

of T3 (some do 24 hours before).

Also when on T3 only you actually do NEED T3 to be OVER RANGE as you don't have

the T4 " pool " .

Why are you on T3 only? Is it because of conversion problems & bad Rt3 Ratio? If

so taking T4 is the LAST thing you should do.

I am postmeno & am on 3mg Estradiol. This is a compounded Liposomal Gel.

taken it for - I am 52 and my oestrogen is declining anyway - do I really need

to add some more. I know nat prog cream stiumulates the oestrogen receptor

sites. What oesterogen do you take. Could you explain again please?!

I disagree. Just because *one* person hasn't felt the need for T4, doesn't mean

others don't need or benefit from it.

This US psych has found T4 has a role in treating mood disorders. I have read

that T4 crosses the Blood brain barrier where it's converted to t3 locally, as

well as some t3 directly crossing the brain barrier. I know I'll get lots of

replies saying only t3 is needed, but there are some cases where it seems T4 is

needed.

The other form you need to know about is T3. You can see in the picture above

that the difference is just one less iodine atom. **Cells in the brain**, liver

and some other organs take T4 from the bloodstream and convert it to T3 by

removing one of the iodine atoms. T3 is the " active " version of the hormone.

About one fifth of the hormone produced by your thyroid gland comes out as T3.

Thyroid hormone as a treatment for bipolar disorder

Thyroid hormones can act as a mood treatment, even when a person's thyroid

levels seem to be " normal " . Read that again, it's really important.

Okay, so does that mean their thyroid levels weren't really " normal " ? This is

probably true some of the time. But in some people, it looks like the hormones,

given on top of the person's usual production, change something in the brain

that changes mood. In at least some cases thyroid hormones are a treatment for

mood problems that aren't thyroid problems in the first place.

Instead, in some cases, these hormones act just like lithium and valproate and

other " mood stabilizers " . They help stop mood cycling -- particularly, it

seems, in people who have " rapid cycling " . This approach is generally used

after a person has tried several of the well-known mood stabilizers, because

there is only a little research about thyroid treatment to go on at this point

(in part because there is no manufacturer in a position to make big money from

the research, for one reason. Thyroid hormone has been around in several forms

for more than 40 years).

Usually the form that is used as a mood stabilizer is T4. By contrast, T3 is

usually used as an " add-on " to antidepressants, because some research has shown

it can boost the antidepressant's effects. One of the reasons to look closely

at thyroid's potential as a treatment is because the risks of this approach,

properly managed, can be extremely low. Therefore, even if the potential

benefit is not very clear (who responds? how often? how much hormone? which

form?), it may still be worth considering when compared to other medication

alternatives with more clearly demonstrated benefits, but higher risks as well.

advantage estridiol at 3 mg post menopausal?

So does oestrogen adversely affect thyroid hormones? Does progesterone help

them?

Keri

*but I do use Serenity as well. Never felt'stable on oestrogen only- but that

was before I learned that oestrogen binds to thyroid hormones and progestrone

transports them- opposite effects*
