Hi ,

There are a few problems with getting reliable sun exposure. One is your

schedule. Say you get busy doing your taxes for a few weeks, or get that end

of quarter crunch at work, pretty soon your serum vitamin D levels dip and

you are back to where you were before. A bigger problem is that most areas

of the U.S. have almost ZERO UV available from October until March. So you

could lie naked out in your yard all day, everyday, and your body would

receive nothing in the way of vitamin D. Even if the day is warm and sunny,

there is virtually nothing there for you.

A better way is oil based vitamin D gel caps. They are dirt cheap, and

really move your blood levels. My 25-hydrox-D (the correct test for vitamin

D) was 19ng. Now it is 57ng. Most experts say the best level you should be

at is between 50-60ng.

This link might help.

And this is the product I take, I can find nothing cheaper that does the

job.

Thanks for the replies.

I'm taking supplemental Vitamin D, so that shouldn't be a problem. I

am interested in a direct correlation between sunlight and

testosterone, though, regardless of the Vitamin D issue. Things like

what this guy is saying:

http://209.85.173.104/search?q=cache:0IgD-flQmNEJ:digg.com/general_sciences/Seas\

ons_change_your_body_shape+testosterone+sunlight & hl=en & ct=clnk & cd=5 & gl=us & client\

=firefox-a

" theres a Direct correlation to testosterone production and sunlight

exposure to the skin. Testosterone production increases significantly

when large areas of the skin are exposed to the sunlight(exposure of

the torso to sunlight for 30 mins or more can increase testosterone

levels well over 100%), For men higher levels of Testosterone cause

the body to burn larger amounts of fat. During the Summer most people

tend to spend more time outdoors under the sun and daylight hours are

longer. The increased exposure and higher levels of testosterone

contribute to the differences in fat. "

But that's just some guy. I'm looking for something more reliable like

a study or something from the medical field. So far I can't seem to

find anything, but there are statements similar to this all over.

My understanding is that for generic white skin, 20 minutes in the sun

during summer months (latitude important too) results in most of the

vitamin D production for the day, about 20,000 IU. As one tans, that

number decreases. On the the other hand, the half life in the body is

something like 2+ weeks. The presentation URL that was posted went into

more details here.

I use a powdered form in capsules and that took my D levels to 63.

Hi Steve,

That is all true, but when you think about it there are some problems.

You have to expose enough skin, like taking your shirt off, lay out for 20

minutes...who has time for this like three times a week, week in and week

out! Also there is the issue of photo aging and skin cancer. I think the

whole skin cancer is overblown, but I know my Aunt who laid out her entire

life looked like a lizard.

Also for six months there is not reliable UV unless you live in San Diego or

Miami and go out exactly at noon. From what I heard those are the only

places that get really any UV in the winter. So back to supplements.

As you get older too the human skin loses the ability to " make " vitamin D,

so even if you do things perfectly you most likely will still be deficient.

I know many have had luck with dry vitamin D3 supplements, but those did not

move my 25-hyrox-D levels at all. It was like I was taking nothing. It takes

the oil based D3 for me. Both the NOW and Healthy Origins brands work for

me. I settled on the later because they are cheaper. I still have to take

8,000iu daily to get up to 57ng/ml. I understand that medical textbooks say

8,000iu is a toxic dose, but with regular blood testing this is not a

problem. The establishment came up with 2,000iu as the max. dose for the

entire population. Since I am only dosing me I don't have to worry about

everyone else.

Hi ,

I have also read that vitamin D might help testosterone. It didn't work for

me though. I got my vitamin D level up to 57ng, but my testosterone still

was falling. It went down to 275 total T before I started injections.

The vitamin D3 did seem to help my HDL, for most of my life it was quite

low. Once as low as 29, but usually in the mid 30's. When I got my D3 levels

up, the last HDL was 71. Unheard of for me. Dr. also sees the D3-HDL

link at his website and blog.

Doubtful you will find any studies on this...there is no money in it for a

sponsor. Vitamin D3 cannot be patented, so no studies.
