Vitamin D and Calcium Absorption - Biochemistry Lesson

Lesson on the role and importance of Vitamin D (calcitriol) in calcium absorption and why we actually need vitamin D for proper absorption and utilization of calcium.

Hey everybody! Here is a lesson on the metabolism of vitamin D, the role of vitamin D calcitriol in calcium absorption and why we actually need vitamin D to absorb calcium in our diet!

Topics discussed in this video:

How is calcium absorbed in the body?

What is Vitamin D Calcitriol?

What is the role of Vitamin D Calcitriol in calcium absorption?

Why do we need to eat Vitamin D?

A video that clears up my confusion after learning biochemistry. Furthermore, would you please offer reference papers or textbooks on how calcitriol promotes calcium absorption? Thanks❤️~

[heinzzoller]

Thanks for this very basic tutorial - Ca transport across the intestine is slightly more complex and it involves trans- and paracellular routes of absorption, which are both Vitamin D responsive.

[judyreyjumamoy]

this is the kind of "how" video that i need
thank you for sharing your gifts, subbed

[eczsvl]

perfect and simple explanation. thanks a lot

[marialaura]

I JUST LOVE IT!! but I would lve it more with the regulation of VIT D and how the PTH and P04 work with vit D

[BlueHoney]

That was great! I'm so excitedly nerdy right now <3

[zakariyaferouz]

Amazing video, I am a pharmacy student and I was having a hard time visualizing this process thank you for the help.

[chiquelemon]

Super helpful, exactly the level of detail I needed. Thanks!

[pinkysplawn]

Why would my stomach not be absorbing vitamin D, been taking it over the counter for years, eat healthy, get sun light, eat healthy, excercise, now on prescription for Vitamin D..prayers for everyone💛

[k.k]

Well this gonna be helpful for my graduation research

[Елена-щпд]

Thank you, I actually thought vit D acts in the lumen, great to remember that lipid soluble vitamins act inside the cell.

[jacobdebernardi]

Great tutorial, however it should be known 600 IU a day will not provide adequate blood levels of vitamin D. It's more to the tune of 10, 000 IU/day, which is what I've taken for 3 years now. My blood tests come out in the mid 50s ng/ml, which is ideal. The only way to know is to get tested.

What happens to the vit. d product after nuclear transcription. Does it get broke down. How is it regenerated or is it removed? This would be important in determining. If a person needed to continuously consume?

[johnmupansa]

What's the need of calcitriol binding to its receptor when it just goes to affact genetic programing directly

[abebarnes]

I love your videos; will you ever get a chance to make a Vitamin A/Retinoids video?

[sadyribeiro]

I have a question : patient with Chronic Renal Failure.. what kind of Vitamin should be given...?

[alexisaac]

No you need more vit d3 than 800iu it's more like in the 4000iu even as high as 10000iu a day. If you live in sun deprived areas. You also need magnesium and vit k to stimulate the absorption of vit d3. Especially now people take more vit d3 than what the health professionals recommend there very guid line driven its frustrating man.

[luckssj]

This is why you need Magnesium Glycinate and Liposomal Vitamin C to make sure that D3 works and the liver and kidneys work
