Risk factors
Research has shown that some people are at a higher risk of developing a vitamin D deficiency than others. Some risk factors to becoming deficient are:
Skin tone
People with darker skin tones are more likely to be at risk of a vitamin D deficiency because they contain more of a pigment called melanin, which reduces the skin's ability to $4 from the sun.

Age
Aging adults are at greater risk of vitamin D deficiency for $4:
