Recent studies have found that high intakes of vitamin D, reduces risk of breast cancer and other diseases. Researchers at the University of California, San Diego School of Medicine and Creighton University School of Medicine concluded that "high intake in adults should be around 4000-8000 IU (unit)".
With this daily measure, all people "would reduce the risk of developing serious diseases like breast cancer, colon cancer, multiple sclerosis and one type of diabetes" said Dr. Cedric Garland, professor of preventive medicine.
This study was published last year in the journal Anti-Cancer Research and even though that recommendation is a lot higher compared to what was traditionally recommended (400 IU per day), it qualifies within a safe range. This report was validated by the National Academy of Sciences and Medicine.
The investigations were conducted on the basis of hundreds of volunteers who took supplements of Vitamin D in doses of 1000-10000 IU / day. Levels were determined from 25-hydroxyvitamin D, which is the way almost all the vitamin D circulates in the blood.
From these results, institutions like the National Academy of Sciences and Medicine exalted that the daily dose of vitamin D should be between the range of 4000 IU / day, valid for adults and children over eight years. Unfortunately, they indicate that very few people fit this pattern of recommendations.
Vitamin D helps the body absorb calcium the bones need to grow, and a deficiency can lead to bone diseases like osteoporosis or rickets. Also plays an important role in the nervous, muscular and immune systems.
You can get vitamin D in three ways: through the skin, diet and supplements. The body forms vitamin D naturally after sun exposure.
We recommend our readers to always consult their doctor about the dose you should consume of any supplement or vitamin, because each body reacts differently.
Vitamin D and the speech of children
Other research by Australian doctors says that Vitamin D deficiency in pregnant women could affect having children with speech difficulties, however this theory needs more studies.
Nevertheless, we recommend that all pregnant women take supplements of vitamin D; doses depend on your doctor recommendation.
For the study, they looked at levels of vitamin D in more than 700 pregnant women. They also evaluated the behavior of children born from these women at ages of 2, 5, 8, 10, 14 and 17.
