Humans only get the ever important Vitamin D from three sources: sunlight, food, or supplements. Since we live in sunny Southern California, many people assume that they are getting plenty of Vitamin D from our 300+ days of sunshine each year, even if we don't get enough in our diet. However, this is not the case, and as such, far too many people are risking heir bone health by not taking a Vitamin D supplement.
