What is vitamin D?

Vitamin D is a group of fat-soluble prohormones, which provide the absorption and metabolism of calcium and phosphorous. It is not actually an essential dietary vitamin in the strict sense, as it can be synthesized in adequate amounts by all mammals from sunlight exposure (an organic chemical compound is scientifically called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from their diet).

Symptoms of vitamin D deficiency

People who get too little vitamin D may develop soft, thin, and brittle bones, a condition known as rickets in children and osteomalacia in adults. Yet even without symptoms of bone pain and muscle weakness, too little vitamin D can pose health risks like increased risk of death from cardiovascular disease and severe asthma in children. Higher blood levels of vitamin D are associated with a lower risk of colon and breast cancer in some age groups.
