This hormone can also be produced in the body naturally as it is found in some foods like fish liver oil, fortified cereals and egg yolks. But the supplements of vitamin D help in boosting the production of the hormone. According to another study, around 60 percent people in the UK are deficient of Vitamin D.
Vitamin D deficiency has a well established association with bone deformation and can lead to rickets. Its role in other health issues is not yet known, but researches are going on this issue. Lead author, Dr Akash Sinha, who also works within the Newcastle upon Tyne Hospitals NHS Foundation Trust, said: “On examining this small group of patients with vitamin D deficiency, which experienced symptoms of muscle fatigue, we found that those with very low vitamin D levels improved their muscle efficiency significantly when their vitamin D levels were improved.”
The fatigue associated with Vitamin D deficiency can be because of the poor mitochondrial functions, after receiving the vitamin D supplement, the system of fatigue improved. Dr Sinha said, “We have proved for the first time a link between vitamin D and mitochondria function.”
