Don’t forget vitamin D

Vitamin D is to calcium what PayPal is to eBay: you need vitamin D to “lock in” calcium from food and get it into your bones. Vitamin D comes from two sources: the sun (UV light interacts with chemicals in your skin to produce it) and foods, including fortified dairy products, egg yolks, salmon, tuna and liver. Health experts recommend a daily intake between 200 and 800 IU of vitamin D per day. Some experts think the daily value is too low and recommend 1000 IU—which generally requires taking a supplement since only a handful of foods are natural sources of vitamin D [fatty fish like salmon, sardines and mackerel; egg yolks supply a little] and fortified milk provides only 100 IU of D per cup.
