Health Benefits of Vitamin D

Optimizing your vitamin D blood levels, whether by synthesis from sunshine or through daily supplementation, benefits just about every life function of your body.

With enough vitamin D in your blood, you can dramatically lower your risk of getting virtually all lifestyle diseases[10] and many chronic diseases. It takes even lower levels of this hormone to prevent the common cold, influenza, and other communicable diseases.

Vitamin D dramatically lowers your risk of getting virtually all lifestyle diseases.

Just about any type of a health problem will be benefited by supplementing with vitamin D. The benefits of vitamin D seemingly can go on forever.

"Like all steroid hormones, 1,25(OH)2D [i.e., D-3 that has been activated both in the liver and Kidney] acts as a molecular switch, activating more than 200 target genes, thereby regulating gene expression. Thus, locally produced 1,25(OH)2D exists in most tissues of the body, is under autonomous autocrine control, and has as many mechanisms of action as genes it targets. This explains why the same substance may have a role in preventing cancer, influenza, autism, asthma, multiple sclerosis, and cardiovascular disease, not just curing rickets and osteomalacia."[10]

To support these health claims you could go disease by disease and list out all the original research studies that have found a health benefit from vitamin D. But, I am NOT trying to publish a research paper, nor is this an academic Web site. The amount of evidence available is simply overwhelming. For the average reader, reading an overview of the health benefits of vitamin D documented in a few published reviews, which are easy reading, should provide more than enough evidence of effectiveness.

DNA researchers have found 2,776 binding sites for the vitamin D re-ceptor along the length of the human genome. Further, they found that vitamin D had a significant effect on the activity of 229 genes, including those associated with Crohn's Disease, Type 1 Diabetes, Systematic Lupus Erythematosus, Colorectal Cancer, Chronic Lymphocytic Leukaemia, Rheumatoid Arthritis, and Multiple Sclerosis.[1] In other words, vitamin D affects just about everything because it has the ability to turn on and off human genes that are associated with a large number of body functions and diseases.

The Simply Amazing Health Benefits of Vitamin D

At this stage, the bulk of evidence for the efficacy of vitamin D on health conditions that go beyond bone health consists mostly of observational epidemiological studies. However, an association does not prove causation, and confounding variables could possibly account for the apparent association. Any confounding factors have to be accounted for mathematically with multivariate analysis. In some case, randomized controlled trial (RCT) studies are still needed. These vitamin D RCT studies do exist for some diseases. They are the types of studies required of pharmaceutical companies before they are allowed to sell new prescription medication. These types of studies take many years to complete and are very expensive. Since vitamin D cannot be patented, there is very little financial incentive for the private sector to finance RCT drug studies.

In natural health circles, prevention is ALWAYS better than cure.

There is more to natural health than just taking a vitamin D supplement. Vitamin D does NOT protect against everything, such as smoking, excessive consumption of alcohol, nor can it negate the overwhelming health negatives of morbid obesity.

Furthermore, your liver and kidneys are vital steps in the synthesis of active vitamin D by your body. The liver changes cholecalciferol, or D-3, into 25(OH)D, the circulating form of vitamin D. Your kidneys changes the substrate 25(OH)D into 1,25(OH)2D, or the activated form of vitamin D. However, we now know that a wide variety of normal tissues, also, have the ability to make 1,25(OH)2D. Ergo, anyone suffering from either chronic liver or kidney disease is going to experience problems trying to benefit from vitamin D therapy.

    • Increased bone mineral density (BMD)
    • Risk of Falls - There was a significant relationship between supplementation of 700 IU/d and decreased risk of falls.[22]

Health benefits of vitamin D - Preventing Cancer

  • DINOMIT Model Of Cancer Development - Offers very compelling reasons as to why vitamin D can both prevent and potentially cure cancer.
  • Risk of Cancer (The risk of dying is dramatically lowered in over a dozen different cancers.)
    "Presently, the role of UVB and vitamin D in reducing the risk of cancer is considered a scientific finding that satisfies most, if not all, the criteria for causality in a biological system given by Hill. The most important criteria appear to be: (1) strength of association; (2) consistency in results for different populations; (3) generally linear dose-response gradients; (4) exclusion of possible confounding factors from explaining the observations; and (5) identification of mechanisms to explain the observations. These criteria are generally satisfied for several cancers in particular and many cancers in general."[2]
    • All-Cancer Risk -
      • "We found that improving vitamin D nutritional status substantially reduced all-cancer risk in postmenopausal women. Furthermore, baseline and treatment-induced serum 25(OH)D concentrations were themselves strong predictors of cancer risk. These findings highlight the importance of promoting optimum vitamin D status and underscore the value of achieving and maintaining a high serum 25(OH)D concentration."[12]
      • Not counting cancers in first year, we saw a 77% drop in cancer rate in the test group.[12]
    • Both vitamin D and calcium have a chemopreventive effect against many cancers. You obtain adequate calcium levels from a good healthy whole Food diet, as well as from supplementation to protect against osteoporosis.
    • Sunshine is inversely correlated with death rates for breast, colon, esophageal, gastric, and rectal cancers.
      • Breast cancer: 50% risk reduction for breast cancer between groups with high (median = 120 nmol/L) vs. low 25(OH)D levels.[17]
      • Colon cancer: 75-80% reduction in risk for colon cancer for levels between 67.5-102.5 nmol/L[14]
      • Prostate cancer - Those who are below the median (62.5 nmol/L in winter and 80nmol/L in summer) have a significantly increased risk of aggressive prostate cancer.[15]
    • Blood: Hodgkin's Lymphoma, Non-Hodgkin's Lymphoma[34]
    • Female: Breast,[6] Endometrial, Ovarian
    • Gastrointestinal: Colorectal cancer,[5] Colon, Bladder, Esophageal,
