Get your vitamin D

Your body needs it to shepherd calcium to your bones -- and unless you're elderly, homebound, or religious about using sunscreen, you probably get plenty from sunlight. Ten to fifteen minutes of sunshine three times a week should enable your body to make all the vitamin D it needs. Just in case, the recommended dietary allowance is that all adults under age 50 get 5 mcg a day (those over 50 need 10-15 mcg). To make this easy for you, the government requires that milk be fortified with the nutrient. Many cereals also contain some vitamin D. If you suspect that you're not getting enough vitamin D from these sources, or if you're over 65, consider taking a multivitamin or a calcium supplement that contains it.
