How Much Vitamin D Do Women Really Need? From Dr. Christiane Northrup (VIDEO)

How much vitamin D should women take daily? Dr. Christiane Northrup says that women over 30 should be getting at least 5,000 IUs of vitamin D per day. During the warmer months, sunbathing in either the early morning or late afternoon with as much of your skin exposed as possible for 30 minutes will maximize your vitamin D intake -- just be sure to wear sunscreen! According to Dr. Northrup, many people are not getting enough vitamin D. "It's a hormone and a vitamin," Dr. Northrup explains, "it's good for cardiovascular health, breast health and mood -- if you have Seasonal Affective Disorder and you take vitamin D, your mood will actually improve." People who maintain an optimal level of vitamin D have a 50% less chance of developing cancer, so it's important to make sure that you're getting enough!
