There's more good news for my favorite nutrient. In a recent meta-analysis, middle aged and elderly people who had high levels of vitamin D cut their risk of developing heart disease or elevated blood sugar nearly in half¹.

Researchers from the University of Warwick evaluated 28 studies involving almost 100,000 men and women across different ethnic groups. The data revealed a significant association between high levels of vitamin D and dramatically decreased risk of both cardiac and metabolic disorders. Compared to those with low levels, men and women who had high levels of vitamin D had a reduced risk of developing cardiovascular disease by about 33%, elevated blood sugar by 55% and metabolic syndrome by over 50%.

Cardiovascular disease is currently the leading cause of death, worldwide. But according to lead author Dr. Oscar Franco, "Targeting vitamin D deficiency in adult populations could potentially slow the current epidemics of cardiometabolic disorders."

As I've said before, I believe vitamin D is the single most important nutrient we can consume. Although the recommendation for adults is only 400 to 800 IU per day, I suggest that most adults consume between 2,000 to 4,000 IU. I personally take 5,000 to 6,000 IU daily and have optimal blood levels of this vital nutrient. Now's the time to get on board with vitamin D!
