When growing up parents are always told us to take your vitamins to grow big and strong. Vitamin deficiency is obviously bad for someones health but scientists have found that having high levels of a certain vitamin can be just as harmful. According to a study conducted by a group of University of Copenhagen scientists, they show that there is a connection between high levels of vitamin D in the blood and cardiovascular death. The scientists conducted a study of 247,574 people over a period of seven years, taking a blood sample from each patient to measure levels of vitamin D. After the seven years the scientists looked at the mortality rate of the patients and found that 16,645 of them have died. They then observed the initial blood sample taken and confirmed that there is a correlation between mortality rate and high levels of vitamin D in the blood.
This was the first time that scientists have been able to reveal that too much vitamin D can be bad for your health. The optimal levels of vitamin D in the blood is about 70 nanomols per litre, and anything under 50 or over 100 may increase the risk of a stroke or a coronary. Most people get enough vitamin D through foods they eat, such as fish and diary products, as well as, vitamin D being naturally made in the body when exposed to sunlight. It is important for people to know that high levels of a certain vitamin can be bad for them because so many people are taking health supplements.
