The vitamins in Norwegian cod liver oil may support immune function, vision, blood sugar regulation, bone health and hormonal regulation. Norwegian cod liver oil also usually contains the omega-3, found in many types of fish oil. This can support brain function, improve mood and prevent cardiovascular disease.

While the benefits of cod liver oil has yet to be definitively proven, research suggests that Norwegian cod liver oil can help to reduce inflammation fight heart disease and diabetes stabilized or even reversing. EPA, a fatty acid omega-3, found in cod liver and other fish liver oils, can significantly help to reduce inflammation in the body. Research into the application of cod liver oil to handle the symptoms of arthritis suggests n that can help regular use of cod liver oil supplements to reduce joint inflammation, relieve joint pain and support joint health.
Many experts believe that cod liver oil and other fish oils may help prevent cardiovascular disease. Anti-inflammatory properties of Norwegian cod liver oil can help reduce arterial inflammation to support cardiovascular health. It can also help to prevent stress-related increases in blood pressure.
Researchers believe that vitamin D, normally found in high concentrations in Norwegian cod liver oil may help improve insulin function to control diabetes. Some believe that cod liver oil supplements can prevent type 1 diabetes in children, and others believe that regular use of cod liver oil may help to write - handle 2 diabetics or even eliminate their re conditions.

While the cancer establishment majority continue looking for a miracle pill as a cure for cancer, other doctors deal again with the concept of healing by way of the diet. It turns out that certain cancers can be prevented or even reversed - not through the development of more expensive drugs but by natural means such as sunshine.
In the laboratory
In an in vitro study treated JoEllen Welsh, a researcher at the State University of New York at Albany human breast cancer cells with a highly effective form of vitamin D. After a few days of this treatment with megadoses of the "sunshine vitamin" shrinking the cells and died from.
»Vitamin D enters the cell and lets them die," said Welsh. She described the process as "similar to the treatment of cells with tamoxifen [a cancer drug side effects in many women cause]." Other researchers repeated the in vitro experiment in mice, where they initially injected breast cancer cells and vitamin D. After a few weeks, the cancer tumors in the mice had shrunk by 50 percent.
Experiments outside the laboratory to date have focused on the preventive effect of vitamin D in cancer. A study published in early 2011 French study found that higher vitamin D levels that were achieved through diet and supplements to lower
Breast cancer risk contributed. The remarkable result of the study, in which more than 60,000 women were observed after menopause for ten years, was that the effect of vitamin D was amplified from the diet, when the women were more frequently exposed to the sun's rays.
Under the direction of Dr. Pierre Engel from INSERM ( Institut National de la Santé et de la Recherche Médicale , National Institute for Health and Medical Research), the researchers discovered that women who lived in areas with higher solar radiation, only half as high breast cancer risk was as in women who lived in areas where the sun was rare.
It seems that the sun exerts a greater therapeutic effect than supplements: In women who took less vitamin D supplements, but abbekamen plenty of sunshine, there was a 32 percent lower risk of breast cancer. However, the greatest protection against breast cancer had the women taking high doses of vitamin D were given about the diet and were frequently exposed to sunlight.
Vitamin D deficiency
At a 2010 conference in Toronto researcher Dr. Cedric Garland explicitly referred to breast cancer than vitamin D deficiency disease, which are characterized by higher levels of the vitamin "virtually eradicated" could. Garland also stressed the importance of sunshine as a source of vitamin D.
However, the benefits of vitamin D is not limited to the health of the breast. As shown by recent studies, it also contributes to the prevention of skin and colon cancer. Furthermore, there is evidence that vitamin D deficiency in many other medical conditions plays a role, such as depression, obesity, diabetes, psoriasis, multiple sclerosis, and osteoporosis.
The ABCs of vitamin D
The recommended daily dose of vitamin D is 200 IU for under 50-year-old, 400 IU for people 50 to 70 years and 600 IU for people over 70 years. Most supporters of natural medicine keep this dosage is too low. Dr. Andrew Weil recently raised his recommendation of vitamin D from 1,000 to 2,000 IU daily. According to this year in the journal Anticancer Research published study by much higher doses are required for protection against cancer - 4000-8000 IU daily for adults.
Vitamin D is a hormone that allows the absorption of calcium in the body. People with dark skin can make vitamin D worse, the same is true in the presence of other hereditary factors. Obesity can affect the function of vitamin D. Certain medications such as anticonvulsant and also sunscreens block vitamin D. Although vitamin D can be absorbed from the sun shining through the skin, the angle of incidence of sunlight in northern climes is six to nine months a year too shallow to a sufficiently high UV radiation to grant. You can let the doctor determine the vitamin D levels by an investigation, to verify that (50-70 ng / ml) it is in the desired range. The best dietary source of vitamin D is unrefined cod liver oil. Also yolk supply (from free-range hens, not from the chicken farm), salmon, mackerel and mushrooms vitamin D.
