Could vitamin D really cure your arthritis? | Mail Online - 0 views

    Now a new and controversial book by an American doctor suggests that taking even higher levels of the vitamin - 10 to 15 times the recommended amounts - can work wonders.

    Dr James Dowd, who works at the Arthritis Institute of Michigan, has been prescribing vitamin D to people suffering from chronic disorders such as arthritis, back pain and headaches and the result, he claims, is a huge improvement in their symptoms.

    In his book, The Vitamin D Cure, Dr Dowd describes a number of success stories using this approach. One of his patients, Barbara, for instance, was obese, and suffered from arthritis in one leg as well as high blood pressure.

    As Dowd explains: "In the past I would have given her anti-inflammatory drugs, pain medication, a pill to lose weight and drug treatment for hypertension."

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

    Add vitamin D to achieve our target serum level . . . HDL jumps to 50, 60, 70, even 90 mg/dl.

    The first few times this occurred, I thought it was an error or fluke. But now that I've witnessed this effect many dozens of time, I am convinced that it is real. Just today, I saw a 40-year old man whose starting HDL was 25 mg/dl increase to 87 mg/dl.

    Responses like this are supposed to be impossible. Before vitamin D, I had never witnessed increases of this magnitude.

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.

The Heart Scan Blog: The Marshall Protocol and other fairy tales - 0 views

    True to form, Dr. John Cannell has published yet another wonderfully insightful Vitamin D Newsletter.

    One item caught my eye, a response to a question about the Marshall Protocol. I, like Dr. Cannell, was inundated with questions about this so-called protocol, which amounts to little more than the unfounded speculations of a non-physician, actually someone not even involved in health care.

    In all honesty, I blew the whole issue off after I read Dr. Marshall's rants. They smack of pure quackery, though from somebody who clearly has a command of scientific lingo. To Dr. Cannell's credit, he took the time and effort to construct a rational response in the latest issue of the newsletter. I reproduce his response here:

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
