Calcium regulation and Thyroid inquiry

And PTH in influenced by ca absorption. 850 mg Ca is optimal (depending on the acido-basic balance).
I thought Peat recommended about 2000mg per day or I'm missing something?

or I'm missing something?I didn't find the source back, except he was talking about a multi-supplement for pregnant women (1200 mg) (in "Nutrition for Women").
Chris Masterjohn: 600 - 700 mg Ca could be right if other parameters are alright. not the target for most people (no safe margin).
And by the way, A hunter-gatherer tribe from Africa does well with 550 mg of Ca.
Chris Masterjohn has said in a post on âDecoding what your body needsâ
"Parathyroid hormone goes up, in either of those situations, not enough D in calcium or too much phosphorus. And if you feed someone meat, which is very rich in phosphorus, it doesnât do anything to their parathyroid hormone. If you feed someone cheese, which is high in both phosphorus and calcium, it decreases their parathyroid hormone, which is a good thing.And if you feed someone packaged foods that have phosphorus additives, it increases their parathyroid hormone, which is a bad thing. So, you have processed foods = bad, meat = neutral, dairy products = good, in terms of affecting the balance of vitamin D, calcium, and phosphorus. So, the reasons for that, probably has something to do with the forms of phosphorus that are added to the food. They might be much more absorbable than the phosphorus from natural food. But itâs also because meat, for example, has amino acids that help you absorb calcium better from your diet. And so, meat isnât just providing phosphorus, itâs also facilitating better calcium status when itâs consumed in the context of a mixed diet. And then, dairy products are actually providing that calcium. So, even though the phosphorus can antagonize the calcium, theyâre providing enough calcium to not only make up for the phosphorus, but to put you in an even better situation than you would be without those dairy products. So, when we look at the calcium requirements, thereâs a gray area because we donât have a lot of data taking people who eat plenty of animal protein, plenty of dairy products, get really good vitamin D status, and donât have any packaged foods in the diet, we donât have a lot of data in those people. And itâs probably the case that calcium needs are lower in those people. Itâs just, I donât know how much lower they are. So my opinion is, you know, shoot for the 1,000-milligram mark, you can probably get away with consuming maybe 600 or 700 milligrams of calcium if you optimize everything else."

@LucH thanks.
I heard also Danny Roddy before mentioning 1500mg Of Ca where required to lower PTH. however, I never thought about the context of the diet can make the difference in the Ca requirement, just like you mentioned.
I think I'm going to set my Cronometer to 1000mg max again.

my down/up limits are set at 650 - 1200 in Cronometer. I target 850 mg Ca. But it doesn't matter much when I reached 80 % of my goals (general), if Mg and K are good.
For instance, last evening I corrected the balance with a dose bicarbonate calcium (1.2 g) and 2/3 dose of Mg bisglycinate (2.5 g x 2/3).
I mind more when the balance between Phophorus to Calcium is to high. The main criterium. P / Ca should be 1/1.2 for RP when targeting the optimal ratio. Never more than twice phosphorus.
Never take a supplement (i don't drink milk) higher than 200-250 mg Ca. Except when I eat spinach (1000 mg Ca citrate) to catch phytate (600 mg per 100 gr spinach).
The ratio Ca / phytate shouldn't be higher than 1/4 (250 mg Ca for 1000 mg phytate) if you don't want to get problems (lithiasis and lack of methylation). -
@LucH thanks
I looked at my cronometer, and on normal days my phosphorous is almost 1300mg and Ca with not supplementation is 1000, so this called for 1500mg tot Ca.
When I eat Liver, I realize my phosphorus shoot to 2000mg.
Do we include the Ca from plant food as well or only from dairy? there may be a good chance the Ca from plant and fruit may not be as available

When calcium is bound to phytate like in nuts, it"s not really available unless you have the nuts soaked. Like in white almond.
Calcium is well available in meat, fruit and most vegetables (the highest in broccoli, 66%, twice more available).
Not very well in manufactured food (biscuit, bread, pizza).
Rather take several mid-portions than high-level portion 'cause the carrier is limited (proportional assimilation). Better take 3 times 250 mg than 750 mg Ca element.
Do not take zinc or iron supplement at the same time as cheese (if more than 40 mg Ca). -
Do you have any feedback on taking desiccated thyroid in proximity to the Ca supplement? I take small amounts of NDT right before breakfast lunch and dinner.
People in the Peat community have confirmed NDT and Dairy is ok, not sure NDT and Ca supplement

I don't take T3 / T4 supplement.
*) In addition, absorption of thyroid desiccated may be decreased and/or delayed by foods such as soybean flour, cotton seed meal, walnuts, dietary fiber, calcium, calcium fortified juices and grapefruit or grapefruit juice. These foods should be avoided within several hours of dosing if possible.
Source:
Thyroid Desiccated Food (search google with âDesiccated thyroid and calcium supplement and possible interactionâ
*) Calcium supplements can interfere with how the body absorbs medications used to treat hypothyroidism.
Take any products containing calcium at least four hours before or after taking thyroid hormone replacement.
Other supplements â especially those containing iron â also can interfere with thyroid hormone replacement. Some foods and other medications can too.

Levothyroxine Interactions with Food Transport
https://mirzoune-ciboulette.forumactif.org/t119p50-the-thyroid-madness#30075
Calcium and iron supplements can interfere with how the body absorbs medications used to treat hypothyroidism. Even with milk. See figure.
One hour before and 4 hours after a Ca take or milk are often advised before taking T4. (1)
But here, on the picture beneath, we see that the uptake T4 is badly influenced until 2 hours after uptake. Leave at least 30 minutes after taking levothyroxine before you drink coffee, tea or fizzy ones.
To avoid interference with interacting agents, a 4 hour-period should be taken into account when managing the dose of a thyroid supplement.
Note: Mind Br, Cl Fl when iodine is required for deiodinase enzymes for conversion T4 into T3. (4)
Minimum delay
Source: Concurrent Milk Ingestion Decreases Absorption of Levothyroxine
450âmg of elemental calcium per 12âoz (355âmL) serving of milk 2% fat.
doi: 10.1089/thy.2017.0428 2018
Conclusions: This is the first study to demonstrate that concurrent cow's milk ingestion reduces oral levothyroxine absorption. The findings support previous literature showing the interference of elemental calcium and food with thyroid hormone absorption. Patients managed with thyroid hormone should be advised to avoid taking their levothyroxine simultaneously with cow's milk. -
thanks. it seems to be in line with another post I found on this forum. Some mention they take NDT with food and dairy to drop the ration of T4 to T3 from 4:1 to 3 to perhaps 2:1.
Danny Roddy in a video I recall was showing a study just delaying absorption, but according to the study you posted, it seems to be doing a little bit of both, delaying absorption and decreasing absorption of T4, probably not that clinically significant when t4t3 combo is used.

They should also mind iodine deficiency in tissues. Especially women (breast).
According to my reading, 150 mcg RDA is not obtained and even not sufficient to deal with the body needs.
I've just read the books of Lynne Farrow. foreword of Dr. David Brownstein
Iodine crisis.
And in French: Les pouvoirs de lâiode. (the powers of iodine). Dr. Vincent Reliquet â PrĂ©vention des Cancers, Lutte contre lâHypothyroĂŻdie, la dĂ©pression, lâEczĂ©ma, la Fatigue âŠ
Réhabilitons cet oligo-élément essentiel à la bonne santé. Préface du Dr. David Brownstein.Excerpt of one post on my forum:
"Administering thyroid hormones to iodine-deprived individuals masks the iodine deficiency and results in a population of zombies, capable of performing physical labor, but incapable of thinking and reasoning properly...â
Dr. Guy E. Abraham, The Original Internist, 2005Rephrased and decoded: Be careful when taking thyroid supplements. If you take an NDT (dried hormone) supplement, even if you have the adequate balance of T3 and T4 in this supplement - assuming of course that you observe a progressive and dosed intake - you will not be able to correct - in the long term - a "slow mood", leading to fatigue, sluggishness, apathy; nor depression and/or insomnia. Not to forget sensitivity to temperature (cold extremities of the hands and feet), muscle pain (fibro), lack of alertness or concentration, being overweight, etc.
The deficiency factor is the bioavailability of iodine and its absorption by tissues, particularly in women (breasts). The explanation will be provided later (on my forum).
Shortly said:Thyroid hormone supplementation masks iodine deficiency.

I read Dr Browstean book years ago and started the Iodine. However, lately I have changed completely my mind about it.
I made a post in the forum, if you have time, watch the video attached to it and let me know what you think about, this is completely the opposite view on Iodine.
