Needing to understand more details about Vit. D supplementation I found these two sites

https://sunlightandvitamind.com/

This page made some reference to sun exposure at "ancestral latitudes" I wanted to read more about that, but can't find it now

This search was prompted by a remark my husband made - he has osteoporosis caused by the anti-androgen treatment of his prostate cancer. His first supply of Vit D, some months ago was in doses of 5000IU. When it was time to replenish stocks I could only find Vit D in strengths of 1000IU, so he has been taking two of those daily for about three weeks now. In the past three weeks, his back pain has been much worse, and he is sure it was better when he took the higher dose of Vit D.
Is it likely that a change in bone pain would occur so quickly as a result of reduced Vit D intake? I think it might have been 2 - 3 days after the change from 5000 to 2000 that his pain worsened.
Of course, he is supplementing with Calcium, magnesium, zinc, selenium and his diet is as close to ideal as we can make it.
I would appreciate any comments about quantities and rate of effects of Vit D.

Looking for adverse effects, there are no problems with sarcoidosis, kidney or liver function. He is a freckled redhead who has always avoided the sun because he burns easily!

Here is the snip referring to ancestral latutiudes. I haven't found the "more later" part yet.
What the research on vitamin D tells us is that unless you are a fisherman, farmer, or otherwise outdoors and exposed regularly to sunlight, living in your ancestral latitude (more on this later), you are unlikely to obtain adequate amounts of vitamin D from the sun.

Thanks Xania. I am very interested in Vitamin D at the moment we are talking about it in my thyroid groups. I keep forgetting to ask the doctor to add it to my tests hopefully next time I will remember

Nutralady, does your doc do tests like this, on request? Lucky you, if he does. Our NHS is restricted in the testing it will pay for, and getting a doc to think outside NHS guidelines in siddicult. I suppose there are private clinics where it could be done, but I don't know of them. Of course, there is always the internet!

I note the lack of response to my first Vit. D query, but I have to ask another question now.
D has been taking Vit D at 5,000 to 6,000 daily. Today he is twitchy, having little muscular spasms, and feels breathless. He think he might have overdosed on Vit D. I can't see the connection, but I want some facts and don't know where to find them.

Xania,

This is the latest research on vit D from Life Extension Foundation:

https://www.lef.org/magazine/mag2007/...itamind_02.htm

This is the second page, which states that toxicity should not result unless more than 10,000 IU is taken. I received a letter from LEF with the results of their latest studies and those that took 10,000 IU of vit D were on the high end of normal. There is lots more research on vit D on the LEF website.

Since vit D appears to be an antifungal, maybe your hubby is experiencing a healing of sorts!? Also, Doug Kaufmann says prostate cancer is actually fungus! I have a book of his that talks about the testing that is done for PSA. They actually test for three types of fungus! In the past, the cure for prostate cancer was antifungals!

Sally B.

Wow - thanks Sally. He hasn't taken that much. I don't think his present symptoms are to do with Vit D, but HE does, so if he stops it for a few days, then feels better, he will be certain!
How do you win with these fellas?

That is a useful link, thanks. "In the past, the cure for prostate cancer was antifungals!"
So why did they change the treatment?

Xania, does your husband take the new type of vitamin k called Vit K2 as MK-7 by Jarrow. It is claimed to facilitate calcium content in the bones and at the same time prevent calcium deposition in the blood vessels.
