GMA Vit D shrinks breast cancer cells

Thanks for posting this-- this news, along with the recently news about aspirin possibly preventing recurrence, is very exciting!

I have been reading and posting on some of the other threads about Vitamin D and I am still a bit confused as to what daily dosage is ideal.  Also would like to know if the liquid (drops) are better than the tablets or caps. I have been taking 1000 iu's in a tablet form, but wonder now if I should increase it.  Now I'm off to the pharmacy to buy some aspirin to take with my D!

And here's another way in which Vit D works to convert Breast cancer cells to innocent cells.

"Carnosic Acid and Vitamin D

Cancer researchers have been paying a lot of attention to vitamin D. Scientists know that vitamin D functions as a hormone, affecting immune response and acting in various ways to protect against cancer.71-74 Vitamin D is available in foods and supplements, as well as through its naturally occurring activation in the skin following exposure to ultraviolet light (sunlight). Vitamin D thus appears to be very important to the body's innate ability to fight cancer.75,76

To complement vitamin's D anti-cancer role, a compound derived from the culinary herb rosemary (Rosmarinus officinalis) acts to enhance vitamin D's biochemical activity. Carnosic acid and carnosol, found in rosemary, are antioxidant polyphenols that have been shown to aid vitamin D's efforts to thwart cancer. Rather than killing cancer cells outright as many chemotherapeutic agents do, vitamin D halts cancer by forcing precancerous cells to differentiate or become, in essence, more mature cells.77,78 Because cancer is characterized by less mature cells, a process that compels these cells to become more mature is beneficial to fighting cancer. Scientists therefore are keenly interested in using supplemental vitamin D for differentiation therapy to prevent and possibly treat cancer.

Beyond this promising partnership with natural vitamin D, researchers have identified other mechanisms by which carnosic acid and carnosol work to protect and enhance the immune system.79 These powerful natural antioxidants exhibit antibacterial activity, even against problematic bacteria that have developed resistance to standard antibiotics.80 Carnosol has demonstrated activity against the HIV virus, at concentrations that were not harmful to healthy cells.81 Much like I3C and DIM, rosemary compounds have also been shown to reduce the carcinogenic potential of natural estrogens by enhancing their metabolism in the liver. When treated with a diet containing 2% rosemary for three weeks, female mice increased their beneficial 2-hydroxylation of estrogens by approximately 150% while inhibiting the detrimental 16-alpha-hydroxylation of estradiol by approximately 50%.82

Glucosinolates and their derivatives from cruciferous vegetables, along with the powerful cancer-fighting compound carnosic acid from rosemary, have thus been shown to be powerful weapons in the battle against cancer."

 I'll be taking rosemary now with my Vit D.
