an acceleration of the cancer. I do recommend vitamin C ascorbate in conjunction with other more important supplements, particularly flavonoids, such as quercetin and/or PCOs (see page 210). I do not usually recommend more than 3,000 mg per day, which is best taken in small, frequent doses: 500 to 1,000 mg three to four times daily along with a complex of flavonoids that include quercetin.
Vitamin D
Vitamin D helps to prevent colon and breast cancers. It is theorized that vitamin D binds with calcium and reduces the turnover rate of the cells that line the colon. Cells that don't turn over are very resistant to carcinogens.
Vitamin D has an inhibitory effect on episomes, submicroscopic circular DNA molecules that carry amplified oncogenes as well as amplified drug-resistant genes. Vitamin D3 is reported to inhibit the incorporation of messages at chromosomal sites, thereby providing a strategy that might make some episomes more susceptible to elimination. 26
Vitamin D may have the ability to inhibit the proliferative activity of hormones, such as estrogen in breast cancer, and has been shown to suppress breast and prostate cancer growth. Sunlight exposure, which leads to an increased level of vitamin D, correlates with a reduced risk of breast cancer. I usually recommend small amounts of vitamin D (400 to 1,000 IU) for those people without sunlight exposure, especially during the winter. I also occasionally recommend cod liver oil during the winter months as a source of vitamin D and omega-3 fatty acids. Vitamin D deficiency is very common in the elderly and in people who live in parts of the world with little sunlight; it is also one of the major contributing factors to osteoporosis.
Vitamin K
Vitamin K is a fat-soluble antihemorrhagic agent comprising three similar compounds:
Vitamin K1 (phylloquinone), found naturally in all green plants
Vitamin K2 (menaquinone), products of bacteria
Vitamin K3 (menadione), a synthetic derivative
