Vit K
I just read an article in the diet and nutrition section about the different vitamins. With regard to Vit K it doesn''t state that it aids the absorption of calcium, yet there are products on the market saying their calcium products are superior as it contains extra Vit K to promote absorption and avoid calcium buildup in the blood stream. Do you have any views on this and the function of vit K?

Dear Jess
The calcium products such as MenaCal.7 which contain vitamin D and vitamin K, were developed after the publication of a large study conducted in New Zealand with more than 1400 adult women. The researchers found that taking calcium supplements without also taking vits D and K, caused an increased in cardiovascular events (i.e. increased risk of heart attacks and strokes). It would, therefore, seem prudent to take calcium supplements that contain vits D and K to ensure that the calcium is deposited in the skeleton and not in the arteries. Vit K is, therefore, regarded as important in the deposition of calcium in the bones, not the absorption of calcium from the digestive tract.
Hope this helps
