VitaminD3 - Ted Hutchinson's blog - 0 views

  •  
    "Thursday, 17 December 2009 This blog is in response to Dr Briffa's post here. as I keep having problems commenting on his blogs. While 44ng/ml is sufficient to not only maximize uptake of calcium (>32ng/ml) and ensure maximum bone mineral density (>42ng/ml), pregnant and nursing mothers should be aware that in order to maximize the amount of vitamin D3 in human breast milk 6400iu/daily was found to be necessary to raise (>58ng/ml) at latitude 32. This is detailed in the Taylor, Wagner and Hollis paper. Vitamin D supplementation during lactation to support infant and mother. Although 4000iu/daily met the mothers daily needs in full it left babies being born with lower 25(OH)D status than required for optimum calcium absorption They also found DAILY use of supplements was required by pregnant and nursing mothers to ensure an even daily Vitamin D3 supply to the foetus & baby. It makes virtually no measurable difference for everyone else if you supplement daily or weekly. While Dr Briffa will not be lactating he may be interested seeing in the Grassrootshealth chart showing disease incidence by 25(OH)D status. this may encourage him to go just another 10ng/ml higher and a bit nearer to the natural level at which human breast milk flows replete with D3."

Vitamin D Testing Errors Continue - The Vitamin D Cure Blog » Blog Archive - 0 views

    "A recent article in the New York Times highlighted an ongoing problem with the accuracy of vitamin D testing at the largest commercial clinical laboratory, Quest Diagnostics. It has become clear from shared experience among vitamin D experts, including myself, that Quest Diagnostics has a problem with seemingly random over-estimation of vitamin D levels."

Maybe Vitamin D Isn't The Answer After All - Dr. Len's Cancer Blog - 0 views

  •  
    "We have been bombarded over the past couple of years with scientific articles suggesting that vitamin D is the key to improving many aspects of our health, including reducing the risks of dying from cancer. An article in this week's Journal of the National Cancer Institute reminds us that perhaps we should be a bit cautious in embracing vitamin D as "the answer" before we do more research. The report, from the National Cancer Institute and the Centers for Disease Control and Prevention, concluded that vitamin D levels in the blood were not related to overall cancer mortality. However, the study did find that higher levels of vitamin D were associated with a substantial decrease in the risk of dying from colorectal cancer, and possibly with a reduction in the risk of dying from breast cancer."

    "I recently received an email from the Vitamin D Council regarding recent evidence that having adequate serum Vitamin D levels could be very important to avoiding illness from the H1N1 (swine) flu that is making the rounds. That will seem intuitive to those of you who read my earlier post about D, but it's good to see some real evidence. Some of you may have seen this information already on other blogs, including Richard's, but I have some new information and some comments to add."

Vitamin D deficiency linked to more colds and flu: Scientific American Blog - 0 views

  •  
    Is sunshine more than just a home remedy for a cold? New research suggests it may be: In a study that will be published tomorrow, people with low levels of vitamin D - also known as the "sunshine vitamin" - were more likely to catch cold and flu than folks with adequate amounts. The effect of the vitamin was strongest in people with asthma and other lung diseases who are predisposed to respiratory infections.

    "Maybe vitamin D isn't the answer after all. Not only does the above statement ring true, it's also the title of a recent post on "Dr. Len's Cancer Blog" - a website written by Dr. Len Lichtenfeld, Deputy Chief Medical Officer for the national office of the American Cancer Society, in order to facilitate communication with the public on important issues related to cancer.

Higher Levels of Vitamin D May Be Associated with a Lower Risk of Lung Cancer in Women ... - 0 views

  •  
    "In a prospective study involving 6,937 men and women, higher levels of vitamin D were associated with a significantly lower risk of lung cancer in women and younger participants. During a maximum follow-up of 24 years, 122 cases of lung cancer were identified. After adjusting for potential confounders, higher serum 25-hydroxyvitamin D levels were associated with reduced risk of lung cancer risk in women (84% reduced risk) and younger participants (66% reduced risk). No association was observed between vitamin D status and lung cancer risk in men and older participants. "

Vitamin D Shows Heart Benefits in Study - Well Blog - NYTimes.com - 0 views

  •  
    "A new study suggests many Americans aren't getting anywhere nearly enough of the vitamin, and it may be affecting their heart health. In the study, researchers looked at tens of thousands of healthy adults 50 and older whose vitamin D levels had been measured during routine checkups. A majority, they found, were deficient in the vitamin. About two-thirds had less vitamin D in their bloodstreams than the authors considered healthy, and many were extremely deficient. Less than two years later, the researchers found, those who had extremely low levels of the vitamin were almost twice as likely to have died or suffered a stroke than those with adequate amounts. They also had more coronary artery disease and were twice as likely to have developed heart failure. The findings, which are being presented today at an American Heart Association conference in Orlando, don't prove that lack of vitamin D causes heart disease; they only suggest a link between the two.

The Heart Scan Blog: Vitamin D and inflammation - 0 views

  •  
    A German group has now shown that the important inflammatory marker, tumor necrosis factor (TNF), is also reduced by vitamin D supplementation. Many studies have implicated increased TNF levels in promoting cancer. In this study, a modest vitamin D dose of 3320 units (83 micrograms) was given vs. placebo. The 25-hydroxy D level reached in the treated group was 34.2 ng/ml (85.5 nmol/L), which resulted in a 26.5% reduction in TNF compared with 18.7% reduction (?) in the placebo group.

    Tufts University Confirms That Vitamin A Protects Against Vitamin D Toxicity by Curbing Excess Production of Vitamin K-Dependent Proteins Tufts University confirmed my hypothesis that vitamin A protects against vitamin D's induction of renal calcification (kidney stones) by normalizing the production of vitamin K-dependent proteins in December, 2008, without citing my hypothesis or telling me they had confirmed it. I am, of course, very grateful that they thought it significant enough to investigate.

The Heart Scan Blog: The case against vitamin D2 - 0 views

  •  
    Why would vitamin D be prescribed when vitamin D3 is available over-the-counter? Let's review the known differences between vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol): --D3 is the human form; D2 is the non-human form found in plants. --Dose for dose, D3 is more effective at raising blood levels of 25-hydroxy vitamin D than D2. It requires roughly twice to 250% of the dose of D2 to match that of D3 (Trang H et al 1998). --D2 blood levels don't yield long-term sustained levels of 25-hydroxy vitamin D as does D3. When examined as a 28-day area under the curve (AUC--a superior measure of biologic exposure), D3 yields better than a 300% increased potency compared to D2. This means that it requires around 50,000 units D2 to match the effects of 15,000 units D3 (Armas LA et al 2004). --D2 has lower binding affinity for vitamin D-binding protein, compared to D3 --Mitochondrial vitamin D 25-hydroxylase converts D3 to the 25-hydroxylated form five times more rapidly than D2. --As we age, the ability to metabolize D2 is dramatically reduced, while D3 is not subject to this phenomenon

Miksi vanhuksemme päätyvät laitoksiin? D-vitamiinin puuteko selittää kansantautimme? Johtuuko suomalainen kansanluonne vain D-vitamiinin puutteesta?

A(H1N1)-influenssa ja D-vitamiini - Terveesti - 0 views

  •  
    Influenssan leviämisen vuodenaikatekijää on haettu 80-luvulta lähtien (Hope-Simpson 1987). Auringon valon saantia ja elimistön D-vitamiinitasojen vaihtelua on jo pitkään epäilty täksi vuodenaikatekijäksi. Viime vuosina tämä yhteys on jo hyvin pitkälle varmistunut kun seerumin D-vitamiinitasoja on opittu mittaaman ja sen myötä on voitu todeta että väestön D-vitamiinitasot elimistössä laskevat voimakkaasti syksyllä ja talvella samanaikaisesti kun influenssa leviää. Lisäksi kun viime vuosina on selvinnyt D-vitamiinin merkittävä asema elimistön immuunipuolustuksen säätelijänä, niin yhteyttä voidaan pitää ainakin suurelta osin selvitettynä eli laskevien D-vitamiinitasojen huonontama immuniteetti altistaa ihmiset influenssalle kuten ilmeisesti monille muillekin infektioille (Cannell 2008).

The Heart Scan Blog: What your doctor doesn't know about heart disease - 0 views

    What causes coronary heart disease or coronary atherosclerotic plaque, this thing that we track with heart scans? Well, here are a few little-publicized facts about heart disease that you are unlikely to hear from your When's-the-next-stent? cardiologist or the What is there besides statins? primary care doctor. (Since everybody knows that smoking is a modifiable risk for heart disease that can be readily identified, let's focus on the blood tests that reveal heart disease causes.)
