American Cancer Society Drags its Feet
A new study of 3,299 persons has shown that those with higher levels of vitamin D cut their risk of dying from cancer in half. Another recent study shows that ample intake of vitamin D, about 2,000 IU per day, can cut breast cancer incidence by half. Still more research found that inadequate Vitamin D is "associated with high incidence rates of colorectal cancer" and specifically urges that "prompt public health action is needed to increase intake of Vitamin D-3 to 1000 IU/day." Vitamin D's anticancer properties are so evident, and so important, that the Canadian Cancer Society now recommends supplementation with 1,000 IU of Vitamin D per day for all adults in winter, and year-round for persons at risk. The American Cancer Society, however, is dragging its feet, still maintaining that "More research is needed to define the best levels of intake and blood levels of vitamin D for cancer risk reduction." What is taking them so long?

Vitamin D Stops Cancer; Cuts Risk In Half

When considering vitamin d supplementation it is reasonable to consider how much vitamin d3 our bodies would make if we lived naked as we evolved. Naturally our bodies attain and maintain a 25(OH)D status between 50ng and 70ng 125nmol/l and 175nmol/l. At this level not only can we meet our bodies daily need for D3 but it is also available in breast milk and can be stored for winter use in muscles and fat tissue.
ReplyDelete1000iu/daily raises status 10ng or 25nmol/l.
Most UK adults average 50nmol/l through the year so an extra 3000iu/daily will raise status to approximately 40ng 125nmol/l and 5000iu/daily to 60ng. Dr Davis of the Heartscanblog operating in Wisconsin (lat) finds women usually require 5000iu/d and men 6000iu/d.
Risk Assessment for Vitamin d shows up to 10,000iu/daily is a safe upper limit.
Sorry typo 40ng=100nmol/l
ReplyDeleteI should also have made it clear that Dr Davis aims to achieve 60-70ng (150-175nmol/l) The higher the status you are trying to achieve the less each extra 100iu/daily of D3 raises so it becomes progressively more difficult.
To reach the status 150ng 375nmol/l at which adverse events have been recorded requires some 40,000iu/daily use for many months before trouble starts.
