STATES CHRONICLE – Researchers are concerned that Americans might be taking too many vitamin D supplements. Studies showed they had started taking more than the daily recommended dosage, which could be risky. There is not much information on the effects of too much vitamin D, but research say it might be harmful.
People have exceeded the daily recommended dosage of vitamin D
A study from 2014 showed that a little bit over 3 percent of American adults took more than 4,000 international units (IUs) of vitamin D every day. This is far more than the recommended dosage, which is 600 IUs for adults younger than 70, and 800 IUs for those aged 70 or older.
Researchers advise people to be extremely careful, since taking more supplements is not always a good thing. There are not many studies looking at how the body reacts to a vitamin excess, but scientists made a few observations. People might end up with too much calcium in their blood, which can produce deposits inside the blood vessels.
Vitamin D is essential to maintain the health of the bones, and some people are afraid that they might not be getting enough. Therefore, in a desperate try to avoid any deficiencies, people take too much of it.
Excessive supplements are not always good
Apart from keeping bones healthy, vitamin D has other advantages as well. These include a lower risk of developing cancer, type 2 diabetes, depression, or even early death. Many people indeed suffer from vitamin deficiency and need supplements, but they should not overdo it.
Researchers looked at surveys and saw how people started taking more and more supplements, until they overpassed the daily recommended dosage by many IUs. This increase was observed among all age groups and ethnicities, but older people, women, and white people were more likely to exceed the limits.
Vitamin D can be acquired from sunlight. Therefore, instead of taking too many supplements and ending up with other health problems, people should spend more time in the outdoors and can their vitamin deposits naturally.
