Vitamin D just won't quit. It seems as though every time I pick up a medical journal, I see scientists have proven that the "sunshine" vitamin can protect you against another disease. This time, it's Crohn's disease.
Crohn's disease is more than just an irritable bowel. It's an autoimmune disorder that creates inflammation in your intestines. Over time, Crohn's disease even puts you at risk for getting colon cancer.
But here's the good news: Scientists now believe vitamin D can protect you against this disease. In fact, in this new study, they've gone one step further. Canadian scientists now believe that a vitamin D deficiency may actually cause Crohn's disease in the first place.
They concluded that everyone should supplement with vitamin D to protect themselves against Crohn's disease. It's especially important – they said – if you have a family history of the disease.
So how much should you take?
Recently, I saw one health guru make a big deal about upping his recommended dosage of vitamin D3 (the most bioactive form of D in the body) from 1,000 IU to 2,000 IU per day. But I've always recommended taking as much as 5,000 IU per day, especially if you live in the northern half of the United States. You just don't absorb enough D from the sun in that part of the country, especially in the winter.
Lastly, remember to take D3 with a meal containing healthy fats, such as olive oil, as this will help your body absorb the nutrient.
