Decreased exposure of the skin to sunlight is a common cause of vitamin D deficiency. [1] People with a darker skin pigment with increased amounts of melanin may have decreased production of vitamin D. [3] Melanin absorbs ultraviolet B radiation from the sun and reduces vitamin D production. [3] Sunscreen can also reduce vitamin D production. [3]
People with low levels of vitamin D have a higher risk of developing rickets (in infants and young children) and osteomalacia, two diseases that can affect bone health and integrity.
Vitamin D deficiency remains the main cause of rickets among young infants in most countries because breast milk is low in vitamin D, and darker skin, social customs, and climatic conditions can contribute to inadequate sun exposure.
Hypovitaminosis D has been associated with many neurological conditions. However, an actual mechanism of action for each of the conditions has yet to be solidified. Many researchers have questioned whether the depletion of vitamin D actually causes these disorders or if vitamin D deficiency is a symptom of these disorders. [medical citation needed]
Try adding foods rich in vitamin D or a vitamin D supplement. Although more evidence is needed, some early research indicates low levels of this nutrient in those with alopecia areata.
The Office of Dietary Supplements recommends getting 15 micrograms of vitamin D a day. Research suggests that low vitamin D levels may also play a role in other common forms of hair shedding, like ...
Likewise, low vitamin D means lower calcium absorption. This double whammy can lead to a vicious cycle of dropping levels, putting us at risk for thin, weakened bones —and, ultimately ...
Vitamin D deficiency: Usually asymptomatic, causes reduce bone density (osteomalacia), rickets, myopathy, and is associated with the development of schizophrenia. It is typically diagnosed by measuring the concentration of the 25-hydroxyvitamin D (25(OH)D) in plasma, which is the most accurate measure of stores of vitamin D in the body ...
