One particular deficiency has been studied over and over again, solidly confirmed as one of the most important nutrients in preventing the development of cancer. This nutrient is the easiest to obtain in states like California and Florida and more difficult to obtain in Northern states and countries. In fact, Dr. Joseph Mercola, speaker & author from the well-known blog Mercola.com, moved from Chicago to Florida in order to access more of Vitamin D. Why would a holistic doctor move from Chicago to Florida for access to the sun?
Let's explore some of the vital studies to understand the power of Vitamin D3. At George's Hospital Medical School in London, Vitamin D production in breast tissue was found to be correlated to a reduction of risk in the future development of breast cancer (1). In fact, women testing with low amounts of Vitamin D were found to increase their risk of breast cancer by 354% (Anticancer Research 26: 2573-80, 2006). This is one reason why I recommend my clients with breast cancer to sunbath with their breast tissue open to the sun rays for 15-30 minutes per day. One of my clients found a dramatic response to sun therapy. During one sunbathing session, after 18 minutes, she literally felt her tumor revolt from the sun and shrink down into the breast tissue. Just 400 IU of Vitamin D per day reduces the risk of pancreatic cancer by 43% (1).
Why is there such a dramatic response such as the one of my client sunbathing? In 1968, J.W. Blunt found the composition of Vitamin D that circulates the blood to be 25-OH-D3 (2). Blunt and his colleagues discovered that 25-OH-D3 was created in the liver and kidneys and acts as a hormone in the body. The hormonal action of Vitamin D3 modulates the immune system and is received on receptor sites of some cancer cells specifically relegated to D3 (2).
When an individual is exposed to Vitamin D from the sun (bare skin with no sun block and no sunglasses so that the body can register that it is in the sun), Vitamin D travels through blood into the liver where is transformed into a prohormone (5). Next, the prohormone form travels to the kidneys where it becomes the active form, calcitriol (5). The kidneys release calcitriol back into the blood where it regulates how the body uses calcium and phosphorus (5).
Receptors for calcitriol are found in the nucleus of cells, the brain, heart, skin, breast tissue, prostate gland and white blood cells of the immune system (6). This is one reason why Vitamin D3 has been more critically linked to breast and prostate cancer although it does impact every type of cancer diagnosis because of its key role in balancing the immune system.
In another clinical trial of D3, patients received a Vitamin D cream to apply on breast tumors. Professor Charles Coomes, the clinical oncologist in Charing Cross Hospital in London found 1/3 of tumors to respond effectively to this treatment (3). A comparison study examining the lives of 133 breast cancer patients found that regular sunbathing (without burning) lowered the risk of breast cancer by 30-40% (4).
Some may find it necessary to make the move to sun-rich states such as California and Florida in order to better access the healing therapy of the sun. However, others may find an effective and therapeutic Vitamin D3 supplement. Cod liver oil is a great supplemental source for Vitamin D3 and the easiest to assimilate because it is a food source. However, not all cod livers oils and D3 supplements are created equal, so choose wisely and carefully. For example, don't buy a Walmart, GNC, or Target brand of Vitamin D3 and expect it to have a therapeutic effect.
Learning from these landmark cancer studies, we can better prevent cancer in the lives of our families and clients. Let us continue to press on and explore landmark cancer studies and eradicate cancer as the lifestyle onset disease that it is by reversing deficiencies, lessening our exposure to toxins and helping our body to heal and find proper balance.
