Wearing my "Vitamin D shirt" (~50% reduction in Vitamin D made from UVB )
How I get some of my vitamin D and exercise in the winter near Seattle - Nov 2016

Amazon Spin cycle, Aero bars IPad/book holder,
sometimes use laptop after removing iPad holder
$451 = $134 UVB lamp, $30 fan, $28 iPad/book holder, $27 aero bars, $232 spin cycle

In Nov 2009 a friend got me interested in Vitamin D. (Vitamin D had eliminated his back pain)
I was astounded as by how much information there was. Really, there was far too much information to make sense of.
It took months for me to sort out the good solid proofs from the associations, much less the possibilities.
It took me another month to understand that 2000 IU was not the upper limit. (10,000 IU a day is great if you take cofactors)
I started taking 2000 IU, increased to 5000 IU daily in December 2009, and 10,000 IU daily in 2011 and 2012, and 12,000 during the winter
My blood test in Feb 2010 = 44 ng/ml, and 129 ng/ml in 2012 (I take all of the vitamin D cofactors, and have done most of the things to increase vitamin D response by at least 2X)
I occasionally take 40,000 IU on days when I am extremely tired. I no longer have any colds
By the way - I live in the part of the US which has the 15 top most cloudy cities - Western Washington.
Have been feeling great. I used to think that I was healthy, but have gotten many great improvements by taking vitamin D.
Have even eliminated winter blues.
Designed this site so that the information is available to everyone around the world via Google translations.
Update July 2013
Still a non-profit, but no longer non-income
Bio-Tech Pharmacal is helping with the on-going expenses of this website and the creation of a short vitamin D video
I have been using their 50,000 IU vitamin D capsule for several years now.
It appears to be the best as well as the lowest-cost form of vitamin D.
Update April 2013
- You can Search VitaminDWiki in many foreign languages (before you could only browse and read)
- Have added a summary of what supplements I take: Vitamin D, cofactors, Omega-3 and why
My Dec 2009 concerns about vitamin D have all been satisfied:
- Which health problem are helped for sure
- Possible long term problems - none seen even for whole countries taking 4,000 IU for more than 10 years
- Not overdose if more than 2,000 IU - however, probably need cofactors if more than 4,000 IU daily
- Half life of Vitamin D in body - 2 months at low levels, 2 weeks at high levels
- Cheese reduces, rather than increases Calcium in the body
- Get no Vitamin D in the winter - wrong, just very little in the winter
- Vitamin D2 is not as good as D3 - before I was unsure if D2 was just not not quite as good as D3
- D3 can prevent heart disease - most likely
- D3 can reduce high blood pressure - yes
- Blood test is recommended - yes, but probably best to start with Vitamin D and just use the test to confirm you are getting enough
- Calcium is needed in addition to Vit D - yes, but if > about 4,000 IU of vitamin D take less then 750 mg of Calcium
- D3 reduces Psoriasis (topical/oral) - yes, had been known for a long time, along with UVB
For most of my life I have been very interested in health, and have taken many supplements daily.
For decades I have enjoyed helping people by providing them with access to information.
Now I can combine those two portions of my life and can say that
if you take only a single supplement it should be vitamin D
Vitamin D will improve your health immediately.
Vitamin D helps health in both the near-term (treatment) and the long-term (prevention).
With the vitamin D my previous medical problems of growing pains, sore tibia, sunburning, etc have gone away
I emailed the following to a friend on our shared 66th birthday, March 2012
Ah, I am 66 years old now but feel like I am in my early 50's (taking 12,000 IU vitamin D daily in the winter)
Lots of vitamin D in the past 2 years
All aches and pains are gone.
My psoriasis on my knee is treated with topical vitamin D
My feet no longer develop cracked skin
Essential tremor in my hands is gone
My neck is no longer sore
My back is no longer sore
My brain is back (able to think and remember much better)
It is a great decade
As I said to the person who got me interested in vitamin D: You have really made my decade (not just my day)
My wife feels 10 years younger too (she is taking 10,000 IU daily)
Not everything has reset to my 50's
Less hair ( but have had great success by vibrating my scalp daily),
gained some weight
Some of the reason for the better brain may be due to my use of Brain Plasticity Software (Posit Science)
Update March 2014 (My 68th birthday)
Other than vitamin D. I bike about 3 tiimes per week (often on a tandem with my wife Judy)
I try to never post information based on a single study, and try to integrate the information
I treat something as a Fact: if there are 3 studies agree and none disagree
I treat something as a Hint if there are 3 studies which agree and 1 disagrees
I treat something as Controversial if 3 studies agree and 2 disagree
My long-term goal: get the world to benefit from Vitamin D
There are so many vitamin D studies now – I just capture the ones with nice abstracts/PDF files
I currently read the titles of about 100 studies daily, read the abstracts of 20,
I make new pages with the abstracts/PDF of about 3
I add the information of another 3 to existing pages
While an additional 3 end up in my backlog - which I rarely have time to get back to.
I have tended to ignore rare/orphan disease - due to time constraints
I am able to see behind the publishers pay-walls (purchased life-long library privileges from my University) but am not allowed to post the information on the web.
Good Health is more than Vitamin D and cofactors – my view Started Jan 2015
Trees found to increase healthy (get outdoors more)
Neighborhoods with more trees are healthier (vitamin D not mentioned) – July 2015
