Vitamin D and Renal Disease Mayo Clinic

Show Description

A commentary by Mayo Clinic Nephrologist Rajiv Kumar, M.D., in the current issue of the journal Kidney International suggests that Vitamin D may improve the treatment of renal disease. Dr. Kumar says that while larger clinical trials are needed, he believes doctors should start treating patients with diabetes who have low serum levels of 25-hydroxyvitamin (the active form of vitamin D) with vitamin D3 to help slow down the progression of kidney damage. Dr. Kumar cautions that more research is needed and that patients should always consult their doctors before consuming vitamin D supplements on their own.

UPDATE: Yesterday the findings of another randomised trial were released, showing that Vitamin D supplementation did not have a significant protective effect on either cancer or heart disease risk: 25 871 participants were randomised to receive either 2000 IU of Vitamin D (Cholecalciferol) or placebo.

After follow up of 5.3 years, there was a 4% reduced chance of cancer and 3% reduced chance of heart disease in the Vitamin D group. However when statistical uncertainty is taken into account, it is very likely that there is actually no benefit from Vitamin D supplementation.

Is it true you can’t get vitamin d from the morning sun? Only midday?

Nalmelsa 2020-08-23 - 21:46

The more vitamin D you get from the sun the quicker you will die.
Sun accelerates aging. Cold temperatures slow down aging.
Harmful UV radiation from the sun is the major cause of premature ageing, sunburn, eye damage, and skin damage leading to skin cancer. Countries get the most sun on their skin live the shortest.
In general countries get the most vitamin D from the sun they have the shortest lifespan, most corrupt, most poverty, most at war, most uneducated, most diseases, most famine, poorest hygiene, most dirty streets, most dirty water, most dirty air, most colonized.

Our produces 10.000 IU to 20.000 IU if we get enough sunlight. So the 1000 IU recommendation is too low for healthy life under natural conditions.

I take Vitamin D3 supplement daily (2000 IU) even though i live in FLA now. I tend to avoid the sun after having a small basil cell cancer removed via Mohs. There are nicer ways to spend the afternoon than having Mohs, but it wasn’t terrible. Plastic surgery that followed another story…..

Working from home since March so i’m not getting much sun, a bit in the afternoon. I’m not super pale (German-English) but 60 now and skin cancer is more of a concern in a place with 250 really bright sunny days per year….. move back to NY and live in the shadow of skyscrapers? Life can never be risk-free.

If you’re darker skinned 1000IU’s isn’t sufficient. Also sunscreen can block the absorption of vitamin D from the sun. You should take vitamin D with healthy fatty foods ( ex. omega 3) as vitamin D is far soluble.

Vitamin D should always be taken with Vitamin K2 (MK-7) to prevent soft tissue calcification of the kidneys and other soft-tissue parts of the body. Also Pyridoxal-5-Phosphate offers excellent renal protection. Those with kidney problem might want to investigate further.

Doc Klioze, thank you about the video.
Can you send me the bibliography about sun exposure times, please?

So remember, you can’t walk under the sun without doctor supervision!
Otherwise you may get too much D3 vitamin!

Masterpiece video on Vit. D❤️
I don’t know why this video is so underrated! There are lots videos on YouTube that are absolute trash but got so many views and likes! And videos like this got overlooked ��.
