| Researchers at the UCLA School of Medicine discovered that vitamin K is a very effective cancer-cell fighter. Tests have shown that vitamin K can stop and sometimes shrink tumor growth. It also acts as a tumor analgesic. 27 Vitamin K 3 has been widely researched in cancer studies. A significant inhibition by vitamin K 3 was observed in several human cancer-cell lines, including breast, ovary, colon, stomach, and kidney cancers, as well as primary and squamous cell carcinomas of the lungs. The inhibition of cancer cells is a dose-dependent phenomenon. Clinical trials using vitamin K 3 and 5-FU for patients with metastatic adenocarcinoma of the breast and colon showed some objective responses that have lasted more than twelve monks in four responding patients It has also been suggested that vitamin K 3 is a radiosensitizing agent. The addition of vitamin K 3 to radiation therapy in patients with cancer of the mouth area increased the survival rate at five years m 39 percent as compared to 20 percent in patients treated with radiation alone.28,29 Vitamin K 1 is derived from vegetable sources and is therefore nontoxic. I recommend a. form of vitamin K 1 created by Scientific Botanicals (see Resources). |
| Vitamin B 6< |
| Many human enzyme systems that involve protein metabolism, catabolism, anabolism, or enzyme production require vitamin B 6 in order to function properly. Vitamin B 6 also improves immune function.30 Pyridoxal-5-phosphate (P5P), the biologically active coenzyme form of vitamin B 6, has been shown to reduce cell growth and kill a number of cell types in culture. The most substantial inhibiting effect was found with metastatic melanoma cells.31 |
| Folic Acid and Vitamin B 12 |
| Folic acid and vitamin B 12 appear to aid in a process that turns cancer genes off by helping transfer methyl groups and their metabolism. When the process, called methylation, doesn't work, as is the case in alcohol abuse, or if the person is on the chemo drug methotrexate, cancer genes produce proteins that may cause cells to proliferate. A methyl-group-deficient diet leading to hypomethylation of DNA and RNA can promote cancer in the liver. A significant body of information suggests that a deficiency of vitamin B 12 can |
