Absolutely worth every single seconds of it to watch!!! HIGHLY RECOMMENDED !! Thank you honestly for explaining this concept in such a wholesome, yet understanble way!👌💥

[anastasiaaa]

Best video i came across. Everytime i forget something i always come to this video. This is my third time

[juanmanuel]

Excellent video!. Its remarkable how this presentation turns such an usually tedious topic (compared to other physio themes) into an interesting one.

[DrHistoryV]

first year medical student here, these videos are partly why I consistently score a few % above the class average

[sumrana]

seriously nobody explains the metabolism and biochemistry stuff in this simple way..Great teaching stuff here will recommend these videos to every other student like me who fails to understand biochemistry

This might help some of you better understand the role of calcitriol:

The observation that calcitriol stimulates the release of calcium from bone seems contradictory, given that sufficient levels of serum calcitriol generally prevent overall loss of calcium from bone. It is believed that the increased levels of serum calcium resulting from calcitriol-stimulated intestinal uptake causes bone to take up more calcium than it loses by hormonal stimulation of osteoclasts. Only when there are conditions, such as dietary calcium deficiency or defects in intestinal transport, which result in a reduction of serum calcium does an overall loss of calcium from bone occur.

Calcitriol also inhibits the release of calcitonin, a hormone which reduces blood calcium primarily by inhibiting calcium release from bone

i agree dr. eric abt the role of vitamin d u have mentioned.. thank u for sharing ur experience sir.. please keep on updating videos on you tube.. great job

[yayisrael]

These videos are so terrific and so clear!!  Thank you!

[svdaedalus]

Thanks for the great video. I watched this after reading the Endocrine Society's 'Choosing Wisely' recommendations for vit D testing.

[JustWanaComment]

Videos and channels like this make make my life

[KrisiMD]

yes!
thank you.
i think i will need to watch it a few more times. but still better than going over it again and again

Interesting. I'm a Capricorn and calcium phosphate is the cell salt that Capricorns need. All my life I've had different issues that can point back to calcium phosphate deficiency. Right now I'm dealing with lots of joint pain and slow muscle recovery. Gonna be supplementing with calcium phosphate soon.

wonderful video, , honestly i'm speechless, , finally I could understand this horrible relations :) :) thank u so much

[shinhwarwu]

Thank you Eric, your lecture is very helpful and easy to understand.  

[RederRafiqMSalih]

Great effort and excellent summary. Thank you

[ned]

My god! thanks for clearing up these Thinga majigger they call Ca Po4 homeostatsis.

[sunving]

Thank you Dr Strong, wonderful lecture, ok no need to correct measure )

I landed on this video after after curiosity on why most institutions recommend 1000mg of calcium in the U.S for adults? I read Harvard studies on why the USDA recommendations may be off because the study was done for a short time period. Also how much calcium does the GI tract absorb and typically how much calcium does the average human being absorb in a day?

[tonyboroni]

just a question i have hypothyroidism high para thyroid hormone pth is 10.9 should be under 7 phosphates level is 1.9 nnmols no kidney damage but liver bones joints and heart puputation and insomnia and fatage and diarrhea if i cant get to the bottom of this i wont live long and dockters wont help me with a diagnoses im dieing and i dont know how to fix it wen i dont know what is causing it.

[ravikumarmeshram]
