The Neglected T3 Thyroid Hormone May Be the Most Important of All
ฝัง

- For decade, endocrinologists have told us that it is useless to test for the T3 thyroid hormone, even refusing to test for the free T3 blood test. They also refused to address low levels of the free T3 hormone by supplementing it or converting levothyroxine (T4) alone to T3-containing preparations such as Armour Thyroid, Naturethroid or others.
Recent evidence, however, proves them completely wrong and, in fact, assessment of T3 levels may be the most important thyroid measure of all.

Thank you! I had my left thyroid taken out at 12 because my pediatrician saw a goiter. I had just had braces put on and cavities filled with mercury. I fainted during ballet class. Took thyroxin till 18 then stopped. I’m 69, still surf, eat Keto, sleep good, very active, take only some important supplements, no pharm pills. Purchasing Reuteri today! ❤
Absolutely fantastic post! Thank you. I’ve been preaching this to who ever will listen. Yes, we need to advocate for ourselves. I’m now 65 I have a list of labs I want my Dr to test, and if they don’t I find someone who will. Sad we have to pay out of pocket sometimes to get the health questions answered. It’s my life and I’m not going to sit around and wait anymore . Thank you again for all the great information you share. Now onto learning to make your yogurt 🙏🏻💕
I do the same thing.
Low t3 3 years. On medication and started iodine 3 months ago. And yes I like these studies, keep it up
You and Dr. Perlmutter saved my life. Thank you. In the 90s I was on my way to “arthritis” and God knows what other disability that would have me dead by now. I totally stopped eating the new low growth, high protein wheat and drove cane sugar down even further than it already was in my diet. My measure of “does it work?” was walking the stairs. In three days the pain started 3-4 steps up instead of when I raised my foot for the first step. In three weeks, no pain till 5-6 steps. And so it went. In my minds eye I still remember and feel my jubilation when after about 11 months I put my foot on the top landing and realized “Oh! I just went up the whole staircase with not even a twinge!” No pain, no “arthritis-it just happens when you’re old-can we replace a hip for you?” No surgery. In my area of the country eating gluten free is a colossal challenge because only one grocery store has a small gluten free section. And it’s expensive. But if this is the cost for being able to live to see my daughter married and to see her child born, I’ll take it. Thank you, doctor, thank you. I don’t understand all you and Dr. Perlmutter say, but _no wheat_ is a simple message I got. That proved a “miracle drug.” Thank you, thank you, thank you with all my heart.
You are awesome Dr. Davis... great respect!!💖👍😉
That is like not testing for insulin. All our metabolic issues can traced to our liver, pancreas, or thyroid and what we are eating. All of these should be addressed every time we see a doctor especially if we already have symptoms.
Thank you Dr Davis. I LOVE these posts where you get down into the biochemistry of these critical health pathways!!! This has inspired me and helped me SO much to take personal responsibility for my own health!
Drs totally dismiss this. They kept me sick a long time as I begged them to address this.
😢❤
Very informative as always thanks ❤
I am 63, been on Synthroid for 35years. On 125 for 5 years. For the last 4 years my RT3 has been high, T4 very high. My Naturopath couldn't say why[said eat more salad]. Cardio and PCP said yes you are on to much. I was displaying very hyperthyroid behavior.
Since 6/2024 I watched Dr Bergs video on 🥰gallbladder and thyroid connection.
Late June I started taking, gallbladder support, liver cleanse, TUDCA, 20 to 30000 D3. MTC. I cut all forms of sugar, all wheat and grain carbs, I eat 2 meals a day. We do not eat out- no premade food- do everything you listed in the video- eat only organic; grass fed grass finished; wild caught ; ect... Worked outside on the property a LOT , I have dropped 22lbs.
Oct. 2024 T4,Free = 1.8 [Normal range: 0.9 - 1.8 ng/dL] TSH = .190LOW [Normal range: 0.550 - 4.780 uIU/mL] Dose lowered to 112
Dec. 5 2024 T4 = 1.7 TSH with reflex to T4 IF IND=1.33LOW dose reduced to 100
Jan 2025 T4= 1.4 TSH with reflex to T4 IF IND= .127LOW Dose reduced to 88
I feel fine, sleeping fine, no palpitations, no hyper behavior. Next blood work March 5th or so.*** I Did read Super Gut*** 🥰
@@ForestFog75 you may need the Wilson temperature protocol just Google.
@Dr Davis - Would be interested to hear your opinion on the emerging discussion around T2, and the potential benefits of supplementing this for those of us who are not getting benefits symptomatically from T3 supplementation.
Thank You for your generous sharing of helpful/healthful information! 🙏
I wonder if you have to inject those compounds for them to work? Seems to be true with many.
Seems 70% get good results, worth a shot.
Thank you for this video!
Wow ! 😮 You are awesome Dr. :)
Very informative. Thank you
So when will the doctors learn , as i see it the most of them don't know shit😢
When we start choosing "FUNCTIONAL or INTEGRATIVE" Medical Doctors!!!😉👍
@@cccalifornia7206 how does one find a functional medical doctor?
Doctors are trained and paid to prescribe meds. Not everyone can be at the forefront of unbiased research like those rare 0.1% doctors....
Very informative! Thank you Dr ❤
I know a few doctors that keep current and are very helpful. Unfortunately there seems to be a vast majority that has taken the. Kool-aid and are stuck in a dogma formed during their time in med school. To be fair, the body is enormously complex and it is a huge effort to become an MD. BUT that internalized knowledge is what was accepted at the time. Research moves on and updates to what was current and accepted need to be applied. Doctors need to stay updated and many don’t. Over the years I’ve tried to get my primary doctors to pay attention to my thyroid. Their “testing” is to look me up and down and say, “You’re not hypothyroid!” I don’t remember there being optical tests for thyroid levels! What I am is physically low functioning and I don’t feel up to par. Then there is health insurance‼️🥵🤬😬
get the fluoride out of your water, toothpaste, food/drinks, meds if you want to help your thyroid.
You are my favourite doctor. Wish to join inner circle. How is monthly fee?
Doc... NatureThroid hasn't been available for years. Armour and NP Thyroid are the most common ones available.
Dr. Davis do you have a protocol for FLORASTRA fermenting in juice?
Only endocrinologists and naturopaths will check your T-3 .
The endocrinologist I saw in Oct and no longer see , never did. She said it was all unnecessary blood work😡
I had the TSH and FREE T- 4 which were normal so says the Dr at 1.01 1.0 she then said i didn't need the T-3 because these were normal so that would be nornal :)
Hi, great conversation, how much iodine? If you’re using the 2% or the 5% how many drops per day for a 60-year-old female? Any help would greatly appreciate it.
Nobody knows. But the docs that are into iodine….25mg(10 drops of 2%) a day for maintenance. Which is also what the bottle suggests, they go to 50-200mg for sick. Some cultures have eaten 80mg a day with no issues
I eat SEA WEED ... as it has iodine in it!!
He cautions if you have Hashimotos to refrain 🧐 I think
I’m a 65 yr. old female and I use Lugol’s 2% at a rate of 8 drops per day.
Take selenium. And d3
from the relation of T4 to free T3 we can derive a conversion intensity... the ACM curves separating the teriles of free T3 nd T4 are nicely inverted. If that conversion drops, it is indicator of metabolic health, particularly insulin sensitivity of the liver and inflammation of the liver, LPS load and CD38. I guess, those factors and high FT4/FT3 ratio are part of the - mitigatable - downward spiral in aging.
The study showing the ACM curves, unfortunately did not include any of these contributors.
Another study "FT3/FT4 ratio is correlated with all-cause mortality, cardiovascular mortality, and cardiovascular disease risk: NHANES 2007-2012" showed that the ratio FT4/FT3 is associated to ACM, but not FT3
thank you
Is it true that high cortisol levels can hender T4 to T3 conversion. My last CBC showed T3 at 37 and the low range started at 71. Cortisol sky high, testosterone low... All after prednisolone from Epic Pharmaceuticals. I had a procedure done in March..My CBC before the procedure where prednisolone was part of the recovery pack, was basically normal.. After prednisolone the CBC panel from a couple of months later when I was wondering what was going on... I got a more in depth CBC panel and it show d what I described above... Aggghhh
Странно. У нас проверяют и Т3, и Т4 и ТТГ.
Yes
Dear Dr Davis, I would appreciate if you would say something about people whose thyroid has been removed. Do we need to measure FT3?
You say everyone needs iodine . In another podcast, you stated that iodine kills the microbes. How can I combine my Reuteri and iodine without killing the beneficial microbes?
Use two hours apart.
Thank you!!!🎉😂❤😅
Can you please share the research that shows methylene blue has an effect on deiodinases, quick AI search says it doesn’t affect
I too would like the research as I take methylene blue and T3 and it seems I should look into this seriously. Thank you.
Informative but confusing, maybe I'm just a dummy. I truly wish I could get some thorough blood work that would look at all these markers. But even then, my doc would probably just want to write a bunch of scrips.
You can order blood work online.
I order my bloodwork from Labcorp, Question or a local lab. They use their own doctors to “prescribe” the tests but it’s cash pay so not to involve your insurance company/doctor, which I appreciate. Fast and easy!
Many ceramic products contain lead in the glazes
Stupid question, does this country for male and females? Or only males?
