You won't hear or read too many cancer clinics and family doctors advising people on maintaining a high D3 blood level to protect against cancer either. The official RDA (recommended daily allowance) for vitamin D3 is way too low to maintain the D3 blood level of 40 to 60 ng/ml (nanograms per milliliter). (http://www.naturalnews.com/031688_vitamin_D_chronic_disease.html)
That's the vitamin D3 blood level promoted by vitamin D3 experts, several holistic doctors, and naturopaths for protecting against cancer. Most doctors still consider 20 ng/ml normal. But PubMed asserts 40 to 74 ng/ml as normal. The possible toxic range is beyond 100 ng/ml, according to the Vitamin D CouncilThe LA Times science section covered a recent study done in Spain by the Spanish Cancer Research Center, and published in the Journal of the National Cancer Institute.
Positive studies on the merits of vitamin D3 for preventing breast cancer, colon cancer, and prostate cancer had already been performed and published. So Dr. Nuria Malets and her team decided to focus on bladder cancer instead. Bladder cancer is an epidemic in Spain.
They divided slightly over 2,000 test subjects in half. One half hospitalized with bladder cancer and the other half without bladder cancer. Then they used the standard serum 25-hydroxycholecalciferol or 25(OH)D test, which measures the active form of vitamin D3 produced in the kidneys.
The Spanish research team recorded that the 1,000 bladder cancer patients had less serum D3 levels than the 1,000 without bladder cancer. They determined that a low vitamin D3 level doubles the chance of bladder cancer.
Separating patients with more aggressivebladder cancers revealed that risks are six times higher with low D3 blood levels. One aspect of vitamin D3's ability to prevent cancer is a protein that D3 provides to curb cancer.
Vitamin D3 is more of a hormone than a vitamin, and it has regulatory adaptogenic properties. It boosts what's needed and lessens what's overabundant.
The LA Times article did not reveal the actual numeric 25(OH)D readings from the Spanish research team to indicate what they considered low.Increasing bare skin exposure to direct sunlight is the optimum vitamin D3 booster. Tanning beds that use UVB (ultra-violet B) rays work also. UVB rays are what helps your skin's fat cells start the vitamin D3process.
Vitamin D3 (not D2) supplements from natural sources are also beneficial. Ignore the official RDA minimum requirement. Many safely and effectively supplement 5,000 to 10,000 iu (international units) daily of natural vitamin D3.
A California study determined that up to 40,000 IU supplemented daily for a short term was not toxic. Your body automatically stops D3 production when sunshine or other UVB rays have your D3 level maxed out.
Instead of relying on frequent mammograms or prostate checks that have proven to give false reads and actually increase cancer risks, boost your vitamin D3 intake with more sunlight exposure to bare skin and/or supplements.
You may wish to check with 25(OH)D testing and decide your dosage from there, or trust your intuition. Try to get the 25(OH)D test from a holistic doctor who understands vitamin D3's implications.
So the vitamin D3 protection plan works for serious diseases as well as maintaining your immunity to help prevent colds and flues. Sunshine is free and vitamin D3 supplements are inexpensive. This is a very cost effective cancer protection plan.
