Being cognitively challenged at times, that was quite a bit of information to absorb so bear with me if this was in Jack's post. In order to get an adequate amount of D3 one must get an adequate amount of sunlight with ultraviolet B. This is challenging for some in many parts of the country. Not so for the southwestern states. When the weather is cooler, I sit out in the sun for 15 minutes a day give or take. When it is hot, as in now, I will sit by a window. Would sitting by the window be enough?

BTW - I lived most my life on Long Island and CT. Additionally, I know of 4 people that were born and raised in AZ that have MS. So I am not 100% convinced on the vitamin D theory.

There is also a good thread on Vitamin D in the vitamin forum.

also I remember an article where they did a test on people in Hawaii (sunny all the time right) and there was a good proportion that had low vitamin D.

So there are people that either do not absorbe well through the sun or dont convert well was what I think it said.

My Vit D was low and I have been supplementing with 1000 iu a day and it has definitely helped with muscle pain and fatigue.

In Rod we trust Go Blue !!! love it Shelley.Well, I sure hope my Vit D levels will be normal in 8 weeks when my neuro will do another blood test to check my levels again,I wonder if she'll want me to stay on Vit D I don't know because I want to stay on it as it sounds like it really can help me.

Go Blue !!!!!

FYi: I had posted this on another forum in May.

There is a great article on Vitamin D starting on page 44 of May 2008 Cooking Light magazine. It predicts that when the new levels get reset in 2010, they will be increased. ( They don't reset nutrition levels but every 10 years.)

"In the absence of it, you're asking the body to defend itself with one hand tied behind its back."

I was surprised b/c it said that a fair skinned person manufactures as much as 15,000 IU in 30 minutes with optimal sunlight conditions, so that is why they think giving people 10,000 IU as a supplement is okay!

The normal values for daily intake are 200 to 400 IU according to your age, but this information is a decade old.

It gives guidelines on the time of day for the sun to be at a 45 degree angle above the horizon and speaks about those of us who live above the 35 degree of latittude ( North Carolina to Southern California).

An spf of just 8 will block 98 percent of your skin's vitamin D production. So we should not have it on all the time.

They suggest having Vitamin D levels checked with bloodwork for something that insurance usually covers like a cholesterol panel or any other annual test. However they think you should always check with your insurance company first.

Most public libraries have Cooking Light magazine in the periodical area.

FYI: I had posted this in another forum last month.

Tkrik, you would be surprised how people modifiy life in Arizona and Texas.

I have lived in both places. By May it is 105 in Az. You go out very early in the am or late evening, when less direct sun to do anything outside. Cars have tint so the temperature does not get so hot your windows blow out.

I'll never forget TX. I remember sticking my head out the door and it felt like I was putting it in an oven. Only when we could go to the pool club did we go out during the day.

Yep Kristi,

Counting down to the start of the season.

If I were you after the 8 weeks I would go on a maintainence dose of like 1000iu a day of D3. Otherwise over time it will just deplete again.

Starfish - Thank you so much. That is the information I was kind of looking for.

I think it is very unwise for amost anyone to exceed 10,000 IU of Vitamin d3.

I take a total of 4,200 IUs of Vit D3 in supplement form daily.

p.s UL = Upper Level intake safe amount

Too much of a "good" thing can actually be really bad if not toxic. I have seen it over and over. Very sad.
