Vitamin D is a fat-soluble vitamin produced in the skin after exposure to sunlight. Advanced age, overweight, lack of fish in the diet, limited sun exposure, along with the use of cosmetics that provide sun protection, and carrying out most activities indoors are just a few of the common risk factors that can lead to vitamin D deficiency.
