Most recently, researchers found vitamin D and calcium supplementation lowered participants’ overall cancer risk by 30%.
Having a serum vitamin D level of at least 40 ng/ml reduces your risk for cancer by 67% compared to having a level of 20 ng/ml or less; most cancers occur in people with a vitamin D level between 10 and 40 ng/ml.
Thousands of studies have been done on the health effects of vitamin D, and research shows it is involved in the biology of all cells and tissues in your body, including your immune cells. Your cells actually need the active form of vitamin D to gain access to the genetic blueprints stored inside.
This is one of the reasons why vitamin D has the ability to impact such a wide variety of health problems – from foetal development to cancer. Unfortunately, despite being easy and inexpensive to address, vitamin D deficiency is an epidemic around the world.
It’s been estimated that as many as 90% of pregnant mothers and newborns in the sunny Mediterranean region are even deficient in vitamin D,1 thanks to chronic Sun avoidance. A simple mathematical error may also deter many Americans and Canadians from optimising their vitamin D.
The Institute of Medicine (“IOM”) recommends a mere 600 IUs of vitamin D per day for adults. As pointed out in a 2014 paper,2 the IOM underestimates the need by a factor of 10 due to a mathematical error, which has never been corrected.
Grassroots Health has created a petition for the IOM and Health Canada to re-evaluate its vitamin D guidelines and correct this mathematical error.3 You can help further this important cause by signing the petition on ipetitions.com.
More recent research 4 suggests it would require 9,600 IUs of vitamin D per day to get a majority (97.5%) of the population to reach 40 nanograms per millilitre (ng/ml). The American Medical Association uses of 20 ng/ml as sufficient, but research shows 40 ng/mL should be the cutoff point for sufficiency in order to prevent a wide range of diseases, including cancer....<<<Read More>>>...
