You've probably heard quite a bit lately about the importance of your gut health. Research in this area is exploding, and for good reason. The more we learn about gut bacteria, the more links we find between these microscopic creatures and every other facet of our health. So it's not surprising that one of those links is close to home for the gut. A healthy gut can lead to a healthy colon, reducing the risk of colon cancer.

Did you know that 80% of breast cancers are estrogen-positive cancers? Most people think that “estrogen positive” means that estrogen caused the cancer. But it doesn’t. However, it does mean that estrogen stimulates the growth of the cancer. That’s why oncologists prescribe anti-estrogen drugs for estrogen-positive breast cancer. What most people haven’t heard is that one of my favorite supplements can make these drugs even more effective.

Many older patients in the U.S. are taking drugs to thin their blood and prevent abnormal blood clotting. The most commonly used one is Coumadin, also known as warfarin. This drug works by interfering with vitamin K. It works because vitamin K is critical for blood clotting. So when you take vitamin K out of the picture, the blood can't clot. But like most vitamins, vitamin K has many other functions in the body besides blood clotting. One of those functions is brain physiology and function. So recently, scientists wondered if taking an anti-vitamin K blood thinner increases the chance of developing dementia.
