Vitamin D is essential for health and vitality.
It helps with calcium absorption in the gut and promotes bone health.
It can help to stave off bone ailments like osteoporosis.
In addition, vitamin D aids with cell growth, immune function and the reduction of inflammation.
The vitamin is also helpful in fighting infections, preventing autoimmune disorders and repairing DNA.
The benefits of the vitamin were discovered in 1914 when a scientist noticed that dogs that were fed cod liver oil didn’t develop rickets.
Hyperparathyroidism caused by tumors in the neck is a popular reason why people experience a vitamin D deficiency.
Diet and a lack of exposure to natural sunlight can also cause the body to lack vitamin D.
Lacking vitamin D is serious business.
Signs of a vitamin D deficiency include unexplained depression, obesity, bone aches, head sweating and gastrointestinal issues. Death can occur if the condition is not addressed. In addition, asthma, cancer and cognitive impairment have all been linked to vitamin D deficiencies.
Absorbing too much vitamin D puts a person at risk for vitamin D toxicity. Toxicity occurs when too much calcium builds up in the blood. Symptoms of hypocalcaemia include weakness, nausea, reduced appetite, frequent urination and kidney issues.
How much vitamin D you should take depends on age.
