WHY IT’S BETTER TO COMBINE VITAMIN D WITH K,
New studies have called vitamin D’s health benefits into question, but are they accurate?
After years of being heralded as a beneficial supplement, with many doctors testing blood levels and prescribing supplements to raise them, vitamin D is starting to become a bit controversial. Some doctors are questioning the wisdom of both testing and supplementation.
No one disagrees with the fact that vitamin D is essential. Until it began to be added to milk in the 1930s, weak bones ( rickets in children and osteomalacia in adults) were major problems. Without enough vitamin D, the body can’t absorb calcium properly, and bones become thin, brittle, and sometimes deformed. In recent decades, studies have found that adequate levels of vitamin D also contribute to many other aspects of health, including:
* Heart health
* Muscle function
* Reduced cancer risk
* Healthier babies
* Less diabetes
* Less osteoporosis
* Stable mood
* Less inflammation
Conflicting Study Results
Despite a clear correlation between adequate vitamin D levels and less risk for many major chronic diseases, results of supplement studies haven’t been completely consistent. Some studies have found that elderly people who take vitamin D suffer from fewer fractures, but others have found no such benefit. Some, but not all, studies show that vitamin D supplements improve levels of blood sugar and reduce winter blues and respiratory infections.
Several factors could help explain these inconsistent results. Studies of
