Vitamin D reduces cancer risk: According to a study from Michigan State University and Hurley Medical Center, vitamin D * should lower the overall risk of cancer. The likelihood of developing cancer is even reduced by 13 percent by raising vitamin D levels. About 80,000 people participated in the study.
Unlike other vitamins, the body can produce vitamin D itself. For this he only needs UV radiation. When the sun rays fall on the upper skin layer, lipoproteins are converted to vitamin D3. So 80 to 90 percent of vitamin D needs can be met. This is 20 micrograms per day. Excess vitamin D is stored in the body to bridge the long winter months without sun.
Many people do not have enough vitamin D in the body
But many people have low levels of vitamin D in the body. Partly because only a small part of vitamin D is absorbed by food, such as oily fish. In addition, we spend less and less time outdoors because of our modern lifestyle and must avoid a few hours of sunshine in the winter. One way to provide the body with vitamin D is through nutritional supplements of vitamin D supplements. These can be taken either in tablet form or as drops.
German Cancer Research Center: "Vitamin D of Special Interest"
"Among the supplements, Vitamin D is of particular interest in cancer prevention The Cancer Information Service from the German Cancer Research Center also writes: "Especially from observational studies, there are indications that a low vitamin D level may increase the risk of cancer and it is now being investigated whether vitamin D supplementation can reduce this risk." However, the Cancer Information Service refers to a 5- annual study with approximately 25,000 participants, completed in November 2018.
- "Of 12,927 participants who received vitamin D, 793 got cancer
- 824 participants in the placebo group with 12,944 participants got cancer
- The risk ratio [HR] was 0.96 with a 95% confidence interval [CI] from 0 , 88 to 1.06
- There was no statistically significant difference between the two groups
Differences between the two groups are likely to be random, according to the Cancer Information Service. Nevertheless, the research continues: "Although the VITAL study will be completed by the end of 2017, it will be followed up over the next two years, and there are other major studies on the topic of vitamin D in cancer prevention."
