Vitamin D3 Deficiency
Main Risk Factors of Vitamin D3 deficiency
Rickets disease develops in a child who is not getting enough Vitamin D and calcium. Although this disease had almost been eradicated after the Second World War, new statistics suggest that almost 40% of young children in the UK now have below the healthy level of vitamin D. There is no calcium deficiency (most people in the UK are getting enough in their diets), it is because of a lack of vitamin D. Without this vitamin calcium cannot be absorbed and get into the bones, muscles and nerves. This data leads some doctors to vitamin suggest that D supplements should be given from 6 weeks of age.
According to Michael Holick, a professor of medicine, physiology and biophysics at Boston University,”whole-body exposure to one minimal dose of solar ultraviolet radiation is comparable with taking an oral dose of between 250 and 625 micrograms (10 000 and 25 000 IU) vitamin D.”2 Using this estimation, some experts suggest 10,000 IU as the upper safe limit in healthy adults.3 Can this amount come from food? One of the richest food sources of vitamin D is wild salmon — you would require to eat 35 ounces (1 kg) a day to get 10,000IU. 4
How common is vitamin D deficiency?
One study in Canada showed that about 22% of Europeans suffer Vitamin D deficiency. The problem is even higher in ethnic groups: 78% of East Asians and 77% of South Asians are deficient. This makes some doctors argue that a healthy daily dose should be 5000 IU.
