Vitamin D is on everyone’s lips these days. The big question is, do we get enough? The short answer is, most of us do from sunshine, fortified milk, certain fish (salmon, mackerel, tuna, sardines), and some dairy products. But if you do not drink vitamin-D-fortified milk, are home-bound, over fifty, use sun-block excessively, are dark skinned, obese, or suffer from malabsorption, you may not be getting enough. Vitamin D is critical for calcium absorption, bone development, and preventing osteoporosis. The older you are, the more you need. An Adequate Intake (AI) of 200 IU (5 mcg) is needed from birth to 50 years old; from 50 to 70 years the requirement is 400 IU (10 mcg), and 71 and older is 600 IU (15 mcg). If you feel you may need a supplement, talk to your doctor. Read more http://ods.od.nih.gov/factsheets/vitamind.asp
