Get Your Vitamin D and Keep Your Heart Healthy

Source: Medline Plus (Summary by NIM)

Yup, vitamin D is making headlines again! This 'sunshine' vitamin is one of the most critical, crucial nutrients in our diets, but it's also one that many of us are deficient in most of the year. As Canadians, it is simply not possible to produce vitamin D from sun exposure for a whopping 6 months of the year, highlighting the need for supplementation. The question that remains is how much should we be taking? New research may add to a growing body of evidence seeking to answer that question.

In the new study, participants to supplemented their Vitamin D intake reduced their rates of diabetes, heart attack, heart failure, high blood pressure and heart disease. They were also less likely to die during the study period. The researchers suggest that individuals should consume between 1,000 and 5,000IU of vitamin D per day, boosting their blood vitamin D concentrations to those higher than considered 'normal'.

Most modern research suggests that for adults, 1,000IU per day is required for optimal health. This, however, is not reflected in the DRI for Canadians, which was set back in 1997 and assumed adequate sunlight exposure.
