Vitamin D linked to Alzheimer's

[Posted: Tue 13/11/2012 by Deborah Condon www.irishhealth.com]

People lacking a particular type of vitamin D may be at an increased risk of developing Alzheimer's disease, a new study suggests.

Vitamin D has a key role in the development and maintenance of strong teeth and bones and is thought to help protect the body against a number of serious conditions, including some neurological diseases and cancer. This latest study relates to vitamin D2. While most people associate vitamin D with sun exposure, vitamin D2 is actually obtained from foods, such as fish, eggs and fortified milk.

UK scientists spent six months analysing the blood samples of patients with Alzheimer's. These included people who were on medication for the condition and people who were not. All were compared with a group who did not have Alzheimer's.

The study found that those with the condition who were not on any medication had very low levels of vitamin D2.

"The vitamin was either non-existent or in such low quantities that it could barely be measured. In comparison, people in the study who were either being treated with drugs to control their Alzheimer's, or who didn't have the condition at all, showed far higher levels," the scientists explained.

They noted that while there has been speculation for some time that vitamin D could be linked to Alzheimer's, this is thought to be the first time a specific connection with vitamin D2 has been found.

Meanwhile, the team also found that drugs used in the early stages of Alzheimer's treatment, known as Acetylcholinesterase inhibitors, may help 'switch on' the body's absorption of vitamin D2.

"Further investigations are now needed to determine whether simple dietary advice or giving a specific supplement could restore beneficial levels (of vitamin D2) in Alzheimer's patients," the scientists commented.

Details of these findings are published in the journal, Current Alzheimer Research.

Alzheimer's disease affects around 35,000 people in Ireland. For more on this condition, see our Alzheimer's Disease Clinic here
I am going to try to raise my Vitamin D2 level above zero. :) The more I read, the more I believe that Vitamins D2 and D3 may turn out to be like the B vitamins in that having a zero blood level of any of the B vitamins is not a good thing.

I have been reading a lot about vitamin D2. The most interesting piece is that just like our skin makes Vitamin D when exposed to the sun, mushrooms placed gill side up also make Vitamin D2 when exposed to the sun.

I have found the following fact written about all over the internet. Here is a quote from Dr. Weil: "In the summer of 2004, mycologist Paul Stamets discovered that the level of vitamin D in freshly picked, indoor- grown shiitake mushrooms rose from 110 IU (international units) to an astonishing 46,000 IU per 100 grams when the mushrooms were placed outdoors in the sun for just six hours with the gills facing up (when the gills were facing down, the level rose to 10,900 IU)."

It's too bad we are going into winter, I'd love to try this myself. In fact, maybe I'll wait for a nice sunny day and do it anyway. A bonus is that I love mushrooms.

I am of course on the D3 band wagon, but it would be nice to see a number other than zero in my next D2 blood test. Especially after the link to Alzheimer's.

Have a great day!

I did not know that D2 could be tested in blood.
What is the name of the blood test you request please?
The blood test was called the Vitamin D [VITD CPT(R)]

The test results stated:
Panel: Vit D 250H
Test: 250H Vitamin D2 -- 0 ng/mL
Test: 250H Vitamin D3 -- 53 ng/mL
Test: 250H Vitamin D Total -- 53 ng/mL
Janet, your D3 is too low, 53 ng/mL is 132.5 nmol/L - PwMS should be aiming for the higher side of 150-225 nmol/L.

Hi Wendy!

Thank you! Perfect timing for your post. I usually take my supplements with breakfast, but in getting the kids out the door and onto the buses this morning, I completely forgot to take them. I'm off to the kitchen now!

Have a great day!
