In reply to thyroid replacement and calcium carbonate, posted by Larry Hoover on August 29, 2003, at 7:45:13
Lar, this is well known..all calcium(not just the carbonate form) affects absorption of thyroid meds(T4)...supplements more so than calcium in food..but even say milk, will reduce the amount of T4 reduced. The affect on T3 meds is not so great ..but still there...so T3 meds are OK to take wth food.(as benefits of slower absorption/release outweigh the loss....but not with calcium supplements.
Also iron stops calcium absorption and vice versa..and all need to be spaced about 4 hrs from thyroid meds(at least I would space iron at least 1 hour from thyroid meds, and preferably 2)...or you adjust your thyroid meds. Basically consistency is the answer for most.
On the other hand ..if you feel hyper a nice big dose of calcium and magnesium is just the thing.
It gets real tricky when you are taking thyroid meds, calcium, iron etc a no of times per day..just don't make days with enough hours <g>...so I just time release my thyroid meds and make dosage adjustments..and purposely take with calcium and magnesium at bedtimeBTW you asked once before abut my meds(not real sure if you want to know?)..
I take 3/8Grain Thyroid extract (similar to Armour) + 25mcgT4 ..in a capsule time released for 8 hrs in MethocelE4M 30% of capsule (have a PDF on methocellulose and breakdown times with combos of startches, sugars, cellulose etc if interested) ..with rice filler ground white rice 70%..(own formula)..call this SRT
take 1 SRT in morning , same around 8 hrs later and at bedtime..this one with calc/mag.
Have been trialling SRT3 in afternoon instead of SRT but the hunger pangs hit badly exactly 15 mins after a taking..so now adding in 500mg tryosine with morning dose.
If I wake at around 4.30AM to 5.30am..often,..then morning dose is taken then..so away from brekkie..usually avoid milk with brekkie..except for bit in cup of tea<g>
Meds designed to time release as best as I can get it to normal body slow release..but I KNOW it's impossible. I do take extra if exercise..but I haven't perfected this as yet..so would be nice if adding in the T4 and tryosine could begin to work! I know about the use of T4 as a "storing house" for T3 on demand...My meds are not great but they sure are one heck of a lot better than just taking them not time released.
I have heard (but still no found the research on) that TSH kinda follows the cortisol circadian rhythm by maximizing at night..probably in early hours of morning. I KNOW TSH is higher in morning than in afternoon. I know that TSH stimulates production of T4(and T3)..so I guess this is maximized in the morning, and you would not need as much at night?..really no idea though.So if anyone knows anything about the daily cycle if thyroid hormone in our bodies could they please let me know,or point me to the source, thanks
I know. I'm making it far too complicated for most.Believe me I was "forced" by my body into it.
I had a really bad reaction to T4 meds low dosage, seemed to shut down my metabolism...rare , but I have heard form 2 others it has happened to as well. Some docs think it is because the small T4 amount is enough to stop your own TSH and thyroid hormone production via pit. feedback (D2 instaead of D1), but does not adequately replace your thyroid hormones.
IMO , this is over simplified ..and I did not get TSH and thyroid hormone tests to "prove" what was happening at the time..as I was too hypo to think or move. I do know tht adding in t4 meds (without reducing my 'Armour" actually caused me to go more hypo this year(by symptoms)..but I am perservering as the T4 does smooth things out.The last blood test showed adding in tyrosine oo actually reduced my T4 and raised TSh. I had thought it would raise TSH, as the extra dopamine should do this..but I surprised my T4 dropped as well. I will keep trying
Sorry long winded. I had a bad reactuion last weekend when I tried up "up" the tyrosine , I also took zinc and selenium. I thought I might have gone over to hyper,. I developed what I thought was a too hish T3 headache(a mild centre forehead headache)..bu then it got worse and turned into a mild migraine..typical for me LHS, behind left eye, left sinus involved and upper teeth on that side (6 and 7). Both eyes very glazed and reddish..and fatigue..spent most weekend in bed..always takes 3 days to get over..and until today was still a bit wiped..that was why I had the blood test. I was NOT hyper. My T4 had gone down and my TSH had gone up. Ft3 was actually a little lower too..but acceptable.
So I had not made myself hyper.
Does anyone knopw what ele can give those symptoms..too much noradrenaline? or too much dopamine? ..Anyone else ever had those symptoms?
