The spread of prostate cancer is caused by the over normal activity of two specific enzymes, proteases called cathepsin and matrix metalloproteinase.

A recent study concluded that Vitamin D can reduce the activity of these enzymes, mainly by increasing the level of counterpart enzymes that inhibit matrix metalloproteinase and cathepsin. This process has two consequences on prostate cancer. On one hand, it creates a limitation in power of prostate cancer cells to invade healthy cells and, on the other hand, it has a positive effect on plasminogen activators, which also are important in uncontrolled prostate cancer spreading mechanism.

For a moment it is unclear whether there are other vitamins and medicines that could increase the anti cancerous effects of Vitamin D. The scientists are now investigating if Vitamin E could be a positive support without increasing the toxic level.

Patients must know that a high dose of Vitamin D has a strong side effect causing kidney problems due of increasing blood calcium levels. For this reason, it should not be taken without medical prescription and a special monitoring of side effects by a professional health care.

Excepting vitamin pills, the best ways to get Vitamin D into the body are to drink milk and to expose the body to the modest sun (sunshine preferable).
