"We are aware of substantial scientific evidence supporting the role of vitamin D in prevention of cancer. It has been reasonably established that adequate serum vitamin D metabolite levels are associated with substantially lower incidence rates of several types of cancer, including those of the breast, colon, and ovary, and other sites. We have concluded that the vitamin D status of most individuals in North America will need to be greatly improved for substantial reduction in incidence of cancer. Epidemiological studies have shown that higher vitamin D levels are also associated with lower risk of Type I diabetes in children and of multiple sclerosis. Several studies have found that markers of higher vitamin D levels are associated with lower incidence and severity of influenza and several other infectious diseases."

Optimal serum 25-hydroxyvitamin D levels for multiple health outcomes. Bischoff-Ferrari HA. Adv Exp Med Biol. 2008;624:55-71. Review. PMID: 18348447 DOI: 10.1007/978-0-387-77574-6_5 Recent evidence suggests that higher vitamin D intakes beyond current recommendations may be associated with better health outcomes. In this chapter, evidence is summarized from different studies that evaluate threshold levels for serum 25(OH)D levels in relation to bone mineral density (BMD), lower extremity function, dental health, risk of falls, admission to nursing home, fractures, cancer prevention and incident hypertension. For all endpoints, the most advantageous serum levels for 25(OH)D appeared to be at least 75 nmol/l (30 ng/ml) and for cancer prevention, desirable 25(OH)D levels are between 90-120 nmol/l (36-48 ng/ml). An intake of no less than 1000IU (25 meg) of vitamin D3 (cholecalciferol) per day for all adults may bring at least 50% of the population up to 75 nmol/l. Thus, higher doses of vitamin D are needed to bring most individuals into the desired range. While estimates suggest that 2000 IU vitamin D3 per day may successfully and safely achieve this goal, the implications of 2000 IU or higher doses for the total adult population need to be addressed in future studies.

Authors of the study reported that carnitine deficiency is a risk factor and should be viewed as a mechanism in hepatic carcinogenesis, and that long-term L-carnitine supplementation prevents the development of liver cancer. Therefore, carnitine supplementation alone or in combination with other natural chemopreventive compounds could be used to prevent, slow or reverse the occurrence of liver cance

Highly effective immuno-modulator used in over 700 clinics as a standard preventative regiment for all incoming patient to reduce the risk of hospital infections. The daily immune supplement of tens of thousands of healthy people in Japan and worldwide, seeking to help their bodies to fight the formation of abnormal cells, whose growth can lead to cancer, chronic disease and infections (such as the influenza / flu virus).

Vitamin D's days of obscurity seem pretty much over. Once just an afterthought to most people-relegated to the sides of milk cartons and the pages of medical texts-it's now on the cusp of becoming a full-fledged disease prevention star. Although vitamin D has long been known as an important factor in bone health, a quickly growing body of evidence now shows that it may also help lower the risk of cancer, heart disease, and even premature death.[1], [2] Not surprisingly, scientists and the public have started to take note, particularly of vitamin D's potential to protect against cancer

"Horseradish Protection Against Cancer and More By Steve Goodman Horseradish: Protection Against Cancer and More Whether it's fighting the flu and respiratory disorders or combating tonsillitis and urinary tract infections, horseradish is a condiment that can help keep you healthy.1-3 Used to treat a wide variety of ailments over centuries, nearly every part of the horseradish plant seems to have some medicinal value. Tea made from its root has been used as an expectorant,1 while tea brewed from its flowers can be used to fight the common cold.3 A poultice can also be made of its roots to externally treat joint discomfort. In addition, raw leaves of horseradish also fulfill a purpose as a natural analgesic and, pressed against the forehead, can eliminate headache pain. Furthermore, an infusion of horseradish has known antibiotic properties,4-6 which have been proven effective against pathogenic fungi.4,5 A perennial plant, horseradish is related to mustard, cabbage, and other cruciferous vegetables. Despite its long history as a versatile herbal remedy, however, perhaps the most interesting health benefit of horseradish is emerging from recent studies of its anticancer effects."

A proprietary extract prepared from co-cultured mycelia of several species of Basidiomycete mushrooms, including shiitake (Lentinus edodes), active hexose correlated compound (AHCC) is extracted from mushrooms using hot water following an enzyme pretreatment, but specific mushroom source and preparation details have not been fully disclosed. Patients use this to prevent and treat cancer. Animal studies suggest that AHCC has antioxidant effects and may protect against disorders induced by oxidative stress (1) and may also enhance resistance against bacterial (2) (7)and viral infections (3). In healthy humans, AHCC increased dendritic cell number and function (4) In vitro and animal studies show that AHCC exhibits some anticancer activities, but the results of these studies are vague

"Berberine is a quaternary ammonium salt from the group of isoquinoline alkaloids. It is found in such plants as Berberis, goldenseal (Hydrastis canadensis), and Coptis chinensis, usually in the roots, rhizomes, stems, and bark. Berberine is strongly yellow colored, which is why in earlier times berberis species were used to dye wool, leather and wood. Wool is still today dyed with berberine in Northern India Berberine (BBR) is a natural compound with up-regulating activity on both low-density-lipoprotein receptor (LDLR) and insulin receptor (InsR). This one-drug-multiple-target characteristic might be suitable for the treatment of metabolic syndrome.[12] Berberine has been tested and used successfully in experimental[13] and human diabetes mellitus.[14][15][16] Berberine has been shown to lower elevated blood glucose as effectively as metformin.[17] The mechanisms include inhibition of aldose reductase,[18] inducing glycolysis,[19] preventing insulin resistance[20] through increasing insulin receptor expression[14] and acting like incretins. Berberine has drawn extensive attention towards its antineoplastic effects.[43][44] It seems to suppress the growth of a wide variety of tumor cells including breast cancer,[45] leukemia, melanoma,[46] epidermoid carcinoma, hepatoma, oral carcinoma, tongue carcinoma,[47] glioblastoma, prostate carcinoma, gastric carcinoma.[48][49] Animal studies have shown that berberine can suppress chemical-induced carcinogenesis, tumor promotion, tumor invasion,[50][51][52][53][54] prostate cancer,[55][56][57][58] neuroblastoma,[59][60] and leukemia.[34][61] It is a radiosensitzer of tumor cells but not of normal cells

"A study conducted by Cedric Garland and other prominent vitamin D researchers determined that women with vitamin D levels above 52 ng/ml have half the risk of developing breast cancer as those with 13 ng/ml! Garland (et al) estimates that 58,000 new cases of breast cancer in the U.S. could be prevented per year by raising vitamin D levels to 52 ng/ml. Imagine what the global impact could be! "

"ANN ARBOR, Mich. - A new study finds that compounds derived from the spices turmeric and pepper could help prevent breast cancer by limiting the growth of stem cells, the small number of cells that fuel a tumor's growth. Researchers at the University of Michigan Comprehensive Cancer Center have found that when the dietary compounds curcumin, which is derived from the Indian spice turmeric, and piperine, derived from black peppers, were applied to breast cells in culture, they decreased the number of stem cells while having no effect on normal differentiated cells. "If we can limit the number of stem cells, we can limit the number of cells with potential to form tumors," says lead author Madhuri Kakarala, M.D., Ph.D., R.D., clinical lecturer in internal medicine at the U-M Medical School and a research investigator at the VA Ann Arbor Healthcare System."

Fish, vitamin D, and flavonoids in relation to renal cell cancer among smokers. Wilson RT, Wang J, Chinchilli V, Richie JP, Virtamo J, Moore LE, Albanes D. Am J Epidemiol. 2009 Sep 15;170(6):717-29. Epub 2009 Aug 3. PMID: 19651663 doi:10.1093/aje/kwp178 These results suggest that the flavonoid quercetin may prevent renal cell cancer among male smokers. The possible risk associated with fish intake warrants further investigation before conclusions may be drawn.
