Does selenium really lower heart disease risk?

A review of observational studies has concluded that higher selenium concentrations in blood are associated with a lower risk of heart disease and vice versa.

But the most important statement in the report is the next one.

“Because observational studies have provided misleading evidence for other antioxidants, the validity of this association is uncertain.”

That’s right, these studies might make good copy for your average newspaper or website looking for something to trumpet. But I think the readers of this blog know better.

Again, the authors rightly conclude, “Evidence from large ongoing trials is needed to establish low selenium concentrations as a cardiovascular disease risk factor. Currently, selenium supplements should not be recommended for cardiovascular disease prevention.”
